Transmission Poll

[Ron Fox]

This poll is just for fun. I know what transmission I want to run but just curious.

Thanks.

[gearheads78]

I would see if you could find an old Doug Nash / Richmond 5-speed :D

JK Already said in the other thread I love my TKO600

$10 says Ron goes with the Richmond!! :rofl: :rofl:

[holschen]

or why not 6l90e soft drivin only put it in D or use the padles....
and press down your accelerator

[Mkelcy]

Powerglide?

[GregWeld]

Powerglide?


Spoken like a true drag racer!

LOL

This is LATERAL G..... it has to have more than two forward gears.

[Flash68]

Lenco! :D

In all seriousness, one of my goals is to have at least one street car someday that has a Lenco behind it.

[BeCool68]

My vote is for the new Richmond 5 speed with over-drive and Long Shifter.

Don't get me wrong i think the TKO is a great tranny too.

I went with the Richmond to handle the torque i am putting to the ground from the 540 BB camaro.

Also was a very easy install and shifts good for me.

Just my humble thoughts. gb

[66LS7]

I have had several standard transmissions & have found that the T-56 does eveything I need it to. The most recent version of the T-56 trans I'm using is the Magnum & am very pleased with the results.:thumbsup:

Cool tranny but it weighs as much as a truck and will suck up a butt load of snort.

Did you have to modify tunnel?

Thanks

[BeCool68]

Did you have to modify tunnel?

Thanks

Ron, we did not have to modify the tunnel, slipped right in.

Very easy install. I believe the new Richmond over drive tranny uses the Richmond 6 speed case, i believe thats what Richmond told me is, so requires a shorter drive shaft. This transmission and shifter are a little pricey compared to some, but i needed something this strong after breaking 2 transmissions before.

I run 755 lbs of torque with my camaro, i have pushed this transmission hard, it truly is bullet proof and runs great on the road coarse. I believe the warranty rating is for 600lbs of torque according to Richmond, granted i do not run slicks so traction is limited but with the DSE Quadralink it does still bite hard.

I run a 308 rear Richmond gear and a 289 first gear in the tranny and .77 in 5th. At 70 mph i am around 2300 rpms's with a 315x17x35 rear tire and allows me 15 miles to the gallon when i keep my foot out it.

Transmission does whine a little but not bad, i have been very happy, with great support from Richmond.:thumbsup:

Are you running a Hurst shifter? Do you have a console?

Can you hear the whine of your transmission over the roar of your motor?

Thanks.

Ron, the Long Shifter is the way to go on this tranny. They have truly designed/engineered a great shifter and is the shifter of choice from Richmond.

I run with a 3 chamber flowmaster so that my bride will ride with me. This has really helped with taming down the engine noise. But when you step into the throttle you will need to prepare for takeoff and hold on, an almost violent roar occurs from this beast. :unibrow:

The whine is not bad at all from the tranny, just tells me a well built tranny is behind this bigblock.

Hi Ron, the Magnum T-56 was installed in our 70 Camaro project "Re-Peeled". The only thing I had to do was cut a hole for the shifter.:thumbsup:

When you say a Long Shifter is this a Hurst Long Shifter or one specifically for the new Richmond?

Does you new bride like riding in the car even if you get on it a time or two? I think my girlfriend is somewhat afraid to ride with me and the car is not even built yet. My daughter is ready to get up and go.

Thanks.

Long shifters are there own brand allowing far better adjustability to make sure you don't miss shifts. gb

[bob442]

what was the intended use again? if its anything other than cruising i would stick with the t-10 if thats what you have. IMO, if not, go with a 6speed, i've read the internals from the camaro fit in a tr400 for a SBC application. i dont know if someone else has mentioned it or ask, but i thought i would add my .02
http://www.tciauto.com/Products/TC-'Street%20Transmissions'-0.aspx

I'm not a fan of the t-56, but thats my opinion, they havent erned a rep for me unless there a rebuilt version like Tremec T-56

The intended use is to have fun with the car by cruising, long distance rides, and maybe the local and close by autocross, etc.

I am not even close to buying a trans but at the moment I am leaning towards the TKO 600. Hopefully Greg is proud of me :thumbsup: (just joking with you Greg)

[GregWeld]

EEEEEEEEEEEEEHHHHHHHHHHHHHHAAAAAAAAAAAAAAAAAAAA!!! !!

Funny -- It's someone elses car - I never really care what they end up with - as long as they're making an INFORMED decision.... and are happy with the result. I just hate to see people make a big costly mistake because I've made them all before myself.

That's why this is a great site with a lot of helpful people like yourself Greg. :thumbsup: It's nice to have a place where I can bounce question's off everyone and get opinions from everyone who has "been there do that."

Thanks.

[79transam455]

Looks like with over half of the votes the T56 is the tranny of choice.

Personally I am putting in a TKO600.

[machota154]

I have the TKO 600 in my Macho TA. It works great with my 3.42 gears. At 72mph it is only turning 2000 rpm. Not that there is anything wrong with my TKO, but I am taking it out and putting in a 4l80e. Shifting is great but I drive a truck for a living and sometimes it is great just to put in drive and go !!!!!!!:D

[Ron Fox]

I haven't purchased a tranny just yet but still leaning towards the TKO 600.

[Roadrage David]

This might sirpize a couple , but i have been road racing ad manual shifting my BTO level3 tr2004r with a stout 461ci 530 hp 577 lbs torque for some time, its flawless and perfect not to use a clutch and breaking on the trans a bit as wel!!.

COOLING is the secred here and not transbraking to agresif.
Im so impressed that im considering (for my new 730 hp 650 lbs torque 7000rpm engine combo) to buy a stronger one from exstreem automatics that can handle 1000 hp!!.
looking at the monsteres clutchles 6 speed from keisler with a price tag of 8000 usd to it the 3950usd for the tr2004r isend al that bad.
also most automatics seem to be able to take more torque then manuals..

[67ragtp]

Ron,
If you do decide to go with a tko600 give a look at Liberty Gear. They have an exclusive (patent) cluster bearing mod that prevents the cluster shaft from getting pushed out the bottom of the case and seals it up properly. especially if your running some ungodly amount of torque. They have figured out all the shifting design flaws in the rails as well. Great group of guys to chat with.

The t56 Magnum is also a great choice.

Rich

[Sieg]

Ron,

Thanks for the thread, I've been researching and debating trannys for my '69 Camaro for a few years.

After reading all the good info in your thread..............I'm still leaning towards the T56 after having a .50 6th T56 in a '94 "Service Package" Camaro. Stielow's cars are my primary inspiration and he appears to have good success with T56's.

I have put my trans decision aside for now since it will be awhile before I need to make that decision.

I know it definitely wont be a Richmond :_paranoid...anyone seen Greg? :D

[KEISLER]

If you are looking for the shift quality of the T56 Magnum, you should check out our KEISLER Rallye Sport RS 5-speed. It utilizes the advanced synchro technology developed by Borg Warner and 3M for the T56 and T45. Parts are directly interchangeable with Viper T56, for example.

The RS shift quality is, in my opinion, better than the T56 because the linkage system in the T56 is massive for the 5/6/R shift rail system. The T56 was originally developed as a truck transmission for GM 1/2 called T55. It never went into production as a truck tranny, but kept the design.

The RS fits our muscle cars with no cutting in most applications - all GM F, A, X, and B-body. This is due to our new transmission case, along with the use of new PerfectFit designed shift components.

All RS transmissions come with a premium shifter mechanism: adjustable but preset solid shifter stops, tunable shifter bias spring (we select the right set for your application), bearing materials under all moving joints, sealed, and no plastic junk anywhere.

Pricing for RS 5-speed kits (incl new dynamic balanced driveshaft, crossmember, isolator, speedo cable/gear, pilot bearing, hardware, console nameplate or shift knob, fully illustrated instructions) starts at $2295 for the RS400 kit, $2595 for the RS500 kit, and tops out at $2995 for the RS600 close ratio 600 torque kit.

The RS uses your stock bell, clutch pressure plate (and fine spline GM disc for 500/600 models), put the shifter exactly in the correct shifter position, and includes a 3 year blanket warranty.

We have been selling the RS for 3 years now as the T45RS in the lower torque format, non PerfectFit design. The RS 5-Speed is a redesign of the T45RS with many new parts, including higher torque capacity 1pc shoot peened 9310 CNC ground gears among others.

RATIOS:
RS400/500 3.37, 1.99, 1.33, 1.0, .67
RS600 *best ratios* 2.80, 1.99, 1.33, 1.0, .67

Hope this helps to give you and everyone else here more insight to the RS, and more choices.

Mini thread-jack

Shafi,

Are you going to have an all inclusive kit for us 67-69 Camaro/Firebird people that can't stand the embarassment of their automatic muscle car? :D

My goal is to get my '69 somewhat track day competent. Current 3:73 posi with Moser axles, 355 ci, 202 heads, GM "Duntov" cam, 650 Speed Demon, that comes to life around 3-3,500 rpm. Will the RS-5 600 close ratio gearing be a decent choice?

I had the car 21 years now and it's about time to increase her fun factor.

Indeed! Check out the complete solution HERE (http://keislerauto.com/gm/camaro-firebird/1967-1969/keisler-perfectfit-kits/*new-item-1967-69-camaro/firebird-5-speed-rs-perfectfit-kit-auto/flypage_tabs.html). I've attached a pic also.

Sounds like the Duntov cam is similar to the one used in the 327ci/365HP Corvette '63-67. I had a '65 Vette with this engine, and it liked to run above 3000rpm also. This motor will work exceptionally well with the RS500 deeper first gear. Those engines like to rev and can use the extra torque multiplication the lower first gear provides. That being said, the 2.80 first gear will motivate the car with less torque multiplication, but less drop in the 1-2. If you shift at 6500rpm, you'll be going 40mph with the RS400/500 and 48mph with the RS600.

Check out a really nice gear speed calculator here (http://www.f-body.org/gears/). Use the ratios to compare the two for your application.

Thanks! I also have the 327/365 Vette heads. Appreciate the gearing input, most vehicles I've had, including bikes have typically had too low a 1st gear, lighting the tires or running out of rpm too soon, making short-shifting to 2nd the norm. Feathering the clutch a little adds to the experience.:D I don't place much emphasis on city driving with the car as I'm in a small town, country roads is where I enjoy it. With 3:55's it could see the taller 1st being a problem, with 3:73's I'm on the edge in your opinion?

Sorry for the jack Ron, hopefully you get some info from the input. :thumbsup:

[Ron Fox]

Thanks Keisler and Sieg. Keep the information coming. The more I hear the more I learn.

The RS 5-speed sounds like a good, all around choice. How many have been sold to this point?

Are there any guys here running the RS 5-speed?

Im in a similar situation 3:73s . Right now I have a 700r4 a 3:06 first gear .
I do trackdays , HSAX stuff . I can usually get to the first turn in first with 330 HP . I will probably never have more than 400 HP at the rear wheels
Do I go with a rs400/500 ? or the rs 600, for the better first gear ?
Once under way I do not expect to need first gear with either trans
I did send Keisler a couple e-mails , no answer yet

[KEISLER]

Hey Folks,

We've been selling the RS400 and 500 in the previous packaging T45RSxxx since 2007, and have hundreds of them in the market. With the new case, and close ratio high torque gearing, along with more than 15 PerfectFit versions came the RS last month. Our run rate on the RS now far exceeds that of the TKO, so we'll start seeing a lot more of these units in the field soon. There are T45RS owners here on Lat-g.

Regarding the gearing, there are a couple of considerations. First, the Overall Ratio in first we like to see in the range of 10.x-11.x so that you will have good acceleration from a launch. When the Overall Ratio gets up to 13.x, you may likely feel the car is overgeared - especially if you have a big block.

To understand the difference in gearing a little better, put it in terms of torque multiplication. Let's say you have an engine putting out 400HP and 400LBFT over the power band. Multiply the torque by the gear ratio, and that is the output torque generated out of the transmission (example: 400 LBFT x 3.37 = 1348 LBFT torque in first gear with the RS400/500; or 400 LBFT x 2.80 = 1120 LBFT with the RS600). That's torque gain is great from the point that you can bring your car into motion quick. The downside is that your wheel rotational speed for any given engine rpm will be slower with the numerically higher gear (ex, 3.37) than with the numerically lower (ex 2.80) first gear. Also, because of the law of physics that energy is neither lost nor gained, the HP at the output of the transmission is inverse multiplication of the HP at the input ... meaning that HP in first gear is 400 HP / 3.37 = 119 HP for the RS400/500, and 400 HP / 2.80 = 143 HP for the RS600. Now, understand that the RS400/500 does not use more power than the RS600 in first gear. But simply it makes more torque, but equally less horsepower.

Gear multiplication occurs once again at the differential, with the main difference being that the diff affects ALL gears. The 3.73 is perhaps the most popular GM performance gear because it offers considerably more torque multiplication across all gears than say 3.36. So the 3.73 happens to be what I have found is on the end of the scale for pairing with the RS400/500 and a big block or hot small block. So, 3.9 and numerically higher we generally pair with the RS600 to prevent over-gearing in first.

Now, you have to put this into context as to your engine's output at a given rpm. For the case of the Duntov cam'd small block, that engine doesn't make a lot of bottom end torque, but likes to rev and make HP on the top end. So, that engine can benefit from the additional torque multiplication to get the car motivating without having to slip the clutch excessively. Combine that with the higher rpm redline to make a really fun blast from first gear. For the case of a low end (rpm) torque monster big block, the numerically high first gear of the RS400/500 coupled with lots of engine torque means there will be a whole lot of torque at low rpms, and the consequence may be excessive wheel spin right from the start.

Looking at real world examples is another good point of reference. All Mustang GT w/5-speed cars since the 90s through 2010 run 3.3 first gear ratios. And there are a lot of fast (10.xx sec 1/4 mile) Mustangs running the 3.3 first gear ratio.

Rolling all of the above into consideration, my general guideline for muscle cars running 25-27inch tires is this:

Engines up to 500 torque and 500 HP:
diff ratio of 3.08-3.73 => use RS400/500
diff ratio of 3.9 & up => use RS600

Engines up to 600 torque and 600 HP:
diff ratio of 3.36-4.1 => use RS600

We always discuss these points with the owner/builder during the quote, and any questions or special considerations (large tires, special purpose apps, etc) can be reviewed.

Hope this helps you all to understand the impact of gear multiplication and selection.

[Sieg]

Thanks Shafi, great delivery of information. Your time is much appreciated.

[Sieg]

How many people have experience converting their car from a mechanical clutch linkage to hydraulic?

How's the pedal feel/feedback?

I can see a few potential benefits:
- Less clutter in the engine compartment
- Ease of installation
- Header clearance
- Use of heavier pressure plates

Any downsides other than price?

[KEISLER]

Hi Sieg,

This is a good question, but I recommend you start it as a fresh thread. And check our customer testimonials section for lots of first hand feedback on this.

I voted "other", and someone wanted to know what "other" meant. Jerico DR-4 4 speed, except I swapped in the road racing sliders, with a GV overdrive here....and a Long Shifters V-gate. Yes, it's a street car.

[TheJDMan]

I also voted "other" and will be using the Jerico WC4.

I flipped the coin for a T-56 Magnum, so you can guess what my thoughts are.

[Ron Fox]

I have not heard much about or read about the Jerico Trans. What are their pros and cons?

[Flash68]

I have not heard much about or read about the Jerico Trans. What are their pros and cons?

Pros: Virtually indestructible, clutchless/precise shifting, many gear ratios available.

Cons: Loud & clunky (if that's a problem for you), generally require more attention/servicing than a true street trans.

[gnx7]

I had a GForce GSR dog box in a race car and it has no business being on the street. The sheer whine is for a race environment only. It shifts instantly and is one bad mofo with a zillion gear ratio options. Another plus is that they are around 60lbs..... saving an easy 70lbs from swapping away from a T56.... and then another 20-30lbs with running a lightweight 7.25" triple disc clutch/PP/flywheel setup (mine was 13lbs total).

Once again... this transmission is not a street transmission by any definition. Straight cut gears and dogs for gear engagement are brutal on the senses over time.
The 4 speed dog boxes are affordable. The 5 speeds which are yet again a step up with little compromise in gearing... are super $$$'s.

Another plus is that they are around 60lbs..... saving an easy 70lbs from swapping away from a T56.... and then another 20-30lbs with running a lightweight 7.25" triple disc clutch/PP/flywheel setup (mine was 13lbs total).

Once again... this transmission is not a street transmission by any definition. Straight cut gears and dogs for gear engagement are brutal on the senses over time.
The 4 speed dog boxes are affordable. The 5 speeds which are yet again a step up with little compromise in gearing... are super $$$'s.

No business on the street? I certainly would not condone daily driving with one, but plenty of people drive dog boxes on the street occasionally just fine. It's not that big of a deal. If you don't like the noise, that's a different issue.

I love the sounds of my T101A (now owned by GForce). Once I get my car back together it will be driven on the street plenty.

I have not heard much about or read about the Jerico Trans. What are their pros and cons?

Greg, thanks for the concern. For the past year or so I have put the car aside. It's been tuff with the death of my brother. I am trying to get back into the build but seems like everytime I think of the car I think of my brother and it tends to drag me down. So at the moment I am trying to get back into it and getting back on Lateral-g seems to help.

At the moment the Bird has its floor, trunk, and both quarters removed. Have a new floor, trunk, and NOS quarters ready to be installed. I have the DSE rear end setup with the mini tubs, subframe connectors, etc. still in their boxes.

With the warmer weather here I know it's time to get going.

What are you into now?

Legend700 5 speed? It would fit your tunnel without cutting

[Ron Fox]

Are a lot of people using the Legend 700?

There are about 700+ Legend700 5 Speeds out there.

I know this post is 5 years old but how many of you (if any) would change their vote to the new TKX 5 speed?

If my HP met the trans specs I'd go with a TKX just for the fitment benefits.

It would save some $$ if you didn't have to raise the trans tunnel.

Money and a lot of work lol.

IMO and strictly my opinion.. I think the step from the 1:1 4th to the .68 5th is a bit much and could bog the rpm down too low. I think the smaller step from 1:1 4th to the .80 5th then the .63 6th is a better transition. Granted, most of us wouldn't see the use of 6th very often but would definitely use that 5th .80, .. Again, just my thoughts
