i have a c5 that has a t56 and clutch and bellhousing


can I use it as a swap in my 88 gta tpi t5


pls let me know


im dying for this

 

It requires rebuilding the trans with several different parts to turn it into a hybrid T56; the parts are like a GTO unit; the ratios would be C5.

If you have a 305 and 3.23 or 3.42 rear, do not bother going with the 2.66 ratios. Save up and change rear axle ratio. Or aim for the wider ratio gear set T56.

Or do the LS1 swap.

 

ok so thats what I wanted to know.


im building a forged 383 with crazy heads and I think my t5 will snap like a twig,


2500usd seems to be 600ft tq t5


do you know any places cheaper

 

First thing would be to price the conversion parts to "GTO" it.
Skip the T5 for a higher torque third gen if you can T56 it.

Tremec Drivetrain parts can be bought cheaper in a time machine.

 

can you tell me list of parts i need to do it


i need it for bigger hp motor

Goes over use of a C5 core.

 

Can you even turn a C5 T56 into an LT1 T56 ? Are the input shafts compatible ? Presumably you want to bolt it to your existing Smallblock ?


If so you would need a new input shaft ($300) New LT1 front plate ($250) New F body rear housing ($300) , New mainshaft ($250), New shift rail ( $ ?). You can find most on ebay. Maybe you get lucky and get some deals ?


Oh ! And a new bellhousing too ($150-300)

 

or sell what you have and purchase a LT1 T56. they are still out there.

 

around where I live there is nothing
but I will post on the fourm here


ty he wanted 2000 cdn for it and considersing I need all that its so not worth it

 

and I have 88 t5 brand new from factory
