T56 Magnum sequential shifter, pros/cons.

[TheJDMan]

I have been running the stock Tremec T56 Magnum shifter for a few years now and have found it to be just marginally acceptable on the street and nearly useless at track speeds. I know I could replace it with any number of aftermarket H pattern shifters all of which are undoubtedly better than what I have. But I have seen youtube videos of sequential shifted T56s and I really like the idea of a sequential shifter. I have found two companies that currently sell a sequential shifter that will bolt on a stock T56 Magnum, S1 and Bremer. Both companies happen to be based in Australia and both shifters sell for about the same money with all the options at about $2400US. I'm looking for feedback from anyone who may have installed a sequential shifter and your experience with them. Might be helpful to discuss the pros and cons of a sequential shifted T56 maybe something I might not have considered.

$2400 for a shifter :headspin: You are crazy to pay that. Sell your Magnum and go buy a G-Force GSR or GF5R dogbox if you want a bad ass affordable transmission.

There is no data for how much this "sequential" shifter actually wears the synchros. Have you tried any of the other shifters available for the T56 Magnum?

Will let you know in a couple months. I have a customer that has one on order and I am ordering the Magnum this week. He didn't want a standard H pattern shifter period.

We would never spend crazy money on something just because we want it... pro touring is nothing if not practical....:lol:

It looks like the S1 has dropped in price recently. I like the appearance and simplicity of the Bremer design for potential shift boot fitment.

I like the idea of a sequential for the track.

I guess I would worry about the tires breaking loose at speed. For example if your car has a tendency to break loose in upper gears (1-2 2-3 shift) at full throttle, and the sequential gearshift change is the hard/fast abrupt change, I am wondering if that would have the tendency to put the car over the edge traction-wise.
As opposed to the H pattern shifter, where you could potentially back-off slightly in the danger area then feather it up to full pedal again.

Any thoughts or experience on this?

[TheJDMan]

Based on the videos I have seen, you can shift as fast or slow as you choose. I really can't see that one of these shifters would wear synchronizers or shock tires any faster than a standard H pattern would. It appears to me that banging gears with either shifter would induce the same amount of wear and drive line shock.


Curious if Mike's customer ever got his shifter in yet.

I really wanted to get a PPG sequential T56 setup, but was quoted 16k for the setup. It's cool but not worth the cash to me. Maybe down the road.

$2400 is peanuts compared to what I have spent on other items in this build. Before this project I would never have considered spending over $1300 per wheel but I did. I have become somewhat numb to parts prices. I like my T56 and don't want a 4 or 5 speed dog box so shifter it will be.

Did anyone ever pull the trigger on one of these? looks like bremer's website is down now.

I talked to Tremec about these bolt on sequential shifters for the T56 Magnum and he said that to make the transmission truly sequential, about $4k worth of work needed to be done inside the transmission in addition to the shifter.

Then you need a PPG gear set at about $17K. A true T56 sequential such as PPG T56 Magnum sequential is about $20k. Then you also have the EG46 from Emco which is not a T56 case but has the exact mounting bolt pattern/dimensions for $26,500. Both are full race capable transmissions used in many racing series.

When you guys say "true", is that clutchless shifting with some kind of electronic cut-out for shifts?

No clutch for upshifts or downshift. Clutch is still used for roll out in 1st and of course reverse. All sequentials have to employ an electronic throttle blip while shifting up to take the load off the input shaft or a throttle rev for downshifts. Something around 15% of throttle input or so. But it is no lift shifting essentially.

This is the T56 Magnum or TR6060 PPG gearset sequential in a 1400hp Viper.

My customer literally got his roughly 7-10 days ago. I have not had time to even schedule the car into the shop yet. Been on indefinite hold.

[Ketzer]

I think the straight gate shifting would still be pretty fun, even if you still had to clutch it... is it $2400 worth of fun? That depends entirely on the owner. I've seen plenty of guys spend extra on something I thought was pointless, and I know that I have done same....

Local guy to me won one of these from the manufacturer on Facebook. Delivered last week. He's gonna be putting the T56 magnum back in his turbo S10 to give it a shot. I said he should let me install it in my car to see how it works.

Still really wish i had the spare funds for a PPG but for the money right now i'm investing it into another project.

[TheJDMan]

Turns out that Greg Weld has a PPG sequential 6 speed in his new track car. But this is a purpose built racecar that will never see any street driving. I don't think the PPG T56 dog box would be very appropriate for the street. I also noticed that the Bremer Shifter's facebook page has a notice that they have suspended production of their sequential shifters. Looks like S1 is the only current option for a sequential shifter. S1 has reduced the price to around $1900.

[Flash68]

The sequential in Gregs' Dirt Bomb Mustang is really cool.

I also vote for a G Force dog box. I have a T101A.

I have the same trans in my car. I've driven a Viper with one, and if you have your ECM programming right, drives like an almost normal car. It is a little clunky, but it's a dog box, they all are. Stop and go traffic, your just going to hold the clutch. Pushing to neutral and back and forth just wasn't worth it to me.

PPG just released a synchronized version of the gear set, so same sequential shift, just have to use the clutch to change gears, but no clunky dog box.

Price on the gear sets has come down to around 14K. I know, still stupid money, but the gear sets can consistently hold almost 2000HP from these Vipers, so your not going to break it!.

The shifter on the PPG just mounts on a plate and is connected via a single mechanical link rod, so the shifter can be mounted about anywhere. I went with an XL tail shaft to move the shifter inline with the steering wheel. Just barely move your hand off the wheel and it falls right on the shifter.

You can see in Greg's vid of Benny driving, he is having to "reach" to shift the car. The shifter location could be moved for better driver ergonomics.

This is at PRI. Billet case and actually cheaper than building a PPG trans.

That new sequential transmission sounds interesting! Can't wait to see it being finally tested and what kind of abuse it can handle.

The Calvo Motorsports Viper was making north of 2000rwhp and torque thru the PPG T56 version. That car puts down a ton of power....
