2005 ctsv t56 swap

[frankv11]

has any body out there used a t56 from ctsv for theyre swap. the t56 will be going in a 69 camaro. by what I can see I would have to eliminate shifter and out put (three prong).

1. will a standard t56 shifter fit

2. how do I change to yoke , do I have to change out put shaft or tail housing,

I have not even touched it yet but figure get as much info as possible before I do

[frankv11]

so I assume nobody has used this type t56 for theyre swap.

I've been wondering this same thing since I have a 68 camaro that I'm swapping a 5.3 with a CTSV t56. Hopefully someone will chime in to answer both our questions

[frankv11]

well I tell you what if I cant change the 3 prong yoke, I could just build a drive shaft that could mate to trans.

now the problem with that is what do you for the rear? because as far as I know U joints create a vibration that is cancelled out with the opposing U joint,( thats why they place u joints 90 degrees from eachother with opposing angles. ) but if I dont have 1 on trans out put shaft im almost sure ill get vibration at around 75mph-90mph

now if I can find a yoke that will mate to a 9" rear end from a 2010 camaro or cts v. may work. chances are slim.

so I guess build a custom yoke to fit rear end or viseversa (trans )

some body out there has to make a driveshaft conversion where both ends are ctsv style joionts ( euro style ) and different type yokes --- splines 27 etc....

if i remember i'll look under the girlfriends cts-v when i get home and look. also yes you would have to change the output shaft on that trans because its a bolt on flange.

the new camaro uses the same design and i had to replace a drive shaft, fuel tank, front and rear flanges and all the bolts and the exhaust system because the 3 bolts that hold it on failed. i would rather have u joints than a rubber cuppler. something to think about.

ok looking at the transmission i am going to say no. there is just too many things that would need to be changed to make it work. the shifter part is the main issue then the output shaft houseing and also the output shaft its self.

too late to backdown I bought italready , I called a few places. I will have to change the tail housing and mainshaft might as well upgrade to the viper shaft. as far as the shifter I looked at it yesterday, it seems like a pretty straight forward shifter so i'm confident it can work.

thanks for taking the time to look under the goat.

whats the reason for GM to use those driveshafts, maybe they needed to reduce vibration (if it was one piece ), but they are two piece front side being shorter than rear?

cts v (not goat) sorry

I have a 56 chevy and just purchased a cts-v TR 6060 out of a 2004. I obviously ran into the same issues as you, which led me here. Just curious to know how this turned out for your project and if it was worth the cost, or if I should just sell the tranny, and get a more conventional one. Thanks, Zimm

Hate to break it to you... The T56 in the 2004 CTSV was NOT a TR6060. It was a standard T56. Just don't want you to think you have something you don't.

I know this is an older thread, but for future reference with people doing searches, here's a bit more detail.

Yes, you can convert the CTS-V T56 to match the GTO version. It's not exactly an inexpensive swap, but you will need to change the following:
-Front plate (GTO / LS Fbody style)
-Mainshaft (GTO shaft)
-Tailhousing (GTO / Fbody style)
-Internal shift rail components (Fbody style)

From the outside measurements, the GTO and Fbody T56's are the same. The stock shifters are different, but that is an easy switch. The main differences are inside. The CTS-V, GTO and Corvette T56's all use the updated and desirable double/triple synchro designs compared to the single/double synchro's of the Fbody's. Also, the CTS-V and GTO's have different gear ratio's for 1st thru 3rd gears as compared to the Fbody units. The CTS-V and GTO's have a lower 1st gear which widens the gear spread a tad but also gives better acceleration down low, especially nice for heavier cars.

On a side note, and the OP might already have found this out, but you can not upgrade the CTS-V to use the Viper mainshaft. Because the Vipers used the older design single/double synchro's, the mainshafts are not compatible with the newer double/triple synchro's of the CTS-V or GTO's. There are other options for an upgraded mainshaft for the double/triple synchro T56's though.....

I hope this clears the mud a little bit.

if this is 85miketpi from ls1tech i spoke to you in regards to swap i'm still on the sidelines as far as moving on with it or selling and buying other.

No, I'm not that person. Just trying to help you and others out in case this topic comes up in the future. :)
