i found a 2005 cts-5 that was totaled from the rear end. the engine and tranny are fine. he wants 3 grand for the car and i want the drive train for my 87 formula. only problem is i dont know what type of tranny the cts-v uses i know the engine is an ls6 so im guessing t56 but if im wrong it would be a waste. anyone know what kind of tranny back the 05 cts-v? also if it is a t56 what is a good set of headers to fit the lsx into a thirdgen?

 

if it is a manual car then it has the t56, automatic then its a 4L65 or 4L80. im not positive on the automatics, maybe someone who knows more about them will chime in. as for the headers, you have three choices. Fourth gen manifolds, hawks longtubes, or custom. the manifolds can be had for pretty cheap, especially if u get them used. the hawks longtubes are about 800, and custom are gonna be the same or more. personally im going with stock manifold as they flow pretty darn good for stockers, and i cant justify spending more on the headers than on my engine itself

 

V's are all t56. The end of the tranny isnt good for our swaps, I think you will need an f-body tranny tail. Engine is an LS2 if its an 05.

 

says ls6 on the strut tower bar.

aside from that i have a t56 torque arm relocator if its the tq arm that is the problem

 

A quick google/ebay search showed it has the tremec T56. It is not in the rear like corvettes and should swap in fine

There were 2 manual trans used in CTS-V's, the tremec and lesser Aisin. If you are sure its a LS6 then it will have the tremec

 

ya the owners manual even says its an ls6. and even so ill probably use the relocator cuz its all i got for a tranny k-member id rather not buy a new one lol. but is there any way i can make sure its a tremec t56 befor i buy tommorow?

 

Take the vin and go to a dealership and ask them to check. Easiest way.

 

Ill let this pic explain what Im saying.

 

oh ok i see... will i be able to find the tail end from a camaro to bolt up?

 

The output shaft is different as well.

The simplest thing to do would be to trade trannies.

 

well i already bought the car im hoping i can part whats left of the front end out to make up for what i paid ill probably do the same thing with the tranny and get one from a 4th gen. thanks for all the help guys
