1992-96 Tremec T56 Conversion Kit Please help!!!
Hi Folks,
I wanted to know if there is any after market conversion kits for corvettes 1992.
I am looking for an aftermarket transmission good for 700LBS of torque. So if there is a tranny out there for my vettte please lead me in the right direction.
Or If there is a way to insure that the current ZF 6speed can handle that type of torque I would love to know.
This must have been done in the past so I know someone must know.

They bought the proceeds of Keisler so should have what you need.

Thanks for the input hcbph... However it seems to be a road block here too. They only offer years C4 1984-1988 ... I am so curious how folks managed pushing power through the 1992 - 1996 its like a lost or forgotten era...I do not know enough about the ZF 6speed yet but if I cant find a replacement that can handle at 700lbs I may just have to stay within the ZF capabilities ...

I think you are underestimating the ZF by a long shot. If you insist, the "older" model kit should plug right in. The T56 isn't as strong and doesn't shift as smoothly with the required offset shifter. I know, i have a T56 in my'86.

I had Rockland build me a ZF to handle 700hp. It has a high cost but built to handle the abuse of racing.http://www.rsgear.com/products/trans...rmance/zf.aspx

Hi Gents ... Well thank you for the replies ... I do not know too much about the ZF potential... I definitely prefer a plug and play solution for my 92 ... So I have been learning about its stock capabilities ... So far I am getting that my 92 is equipped with the older version rated at 450 LBS... I saw the Rockland option and I was transferred to support but voice mail came on. I am also confused if its just an automatic option I own a 6speed
Thanks Jonny Mac for confirming that indeed we can beef up the ZF. If you can provide me with details that would be awesome (order #) I am also wondering if the ZF transmission that Rockford offers is plug and play for my 1992...

Just to bring you all up to speed of the build in progress .... Forged 383- efi connection 24x LS1 PCM with LS7 Coils (yes I had to get the harness custom made by Current performance wiring)AFR 210 LT4 ELIMINATOR heads married to a EDELBROCK LT4 Intake... with 60lbs injectors and finally a DS1C Pro charger... So far we are at the 383 efi and 60lbs injectors.

Much of the T56 info you'll get here is bias and uninformed since 99% of the readers are ZF owners. The T56 can be easily and inexpensively built for 700hp+ and with proper parts shift smoothly to 8500rpms. I designed and built my 1000hp T56 for $1900 and have installed in my '92 for almost 2 years now.
Now finding the CBeam T56 adapter might be another story...

The stock ZF should be fine in your application. The factory rating of 450 torque is continous, if you are hitting it with a nitrous shot to 600 for short term acceleration it will be fine.

Thank you for that insight. bjankuski..At this point a plug and play solution is most desirable so to hear its stafe for short term use over its rating does offer some comfort... however I would like the peice of mind of WOT at will... this is why I want a high rated LBS transmission. I do not know enough about either the ZF 6 or the T56 but what I am gathering is 1992-1996 isn't plug and play for the T56 ... and the ZF 6 upgrade is limited. I don't mind modifying if anyone can lead me in the right direction for parts needed etc or a custom shop who would sell a kit. or the other option to beef up my ZF

Will the car be use for drag racing? Will you be running drag slicks? If you haven't already done so, consider that the rest of the driveline will have to be able to take that level of power.
Have you looked at the "Black tag" ZF6 trans? I believe these were the ones that were installed in the ZR-1 cars. They will be stronger than the trans that came behind the LT1 motors.

Agreed the plan is to follow the drivetrain to accommodate the entire combination.
From what I gathered any of the ZF stock platform was good between 400 - 450 lbs black tag being the latter

You would be fine with a standard ZF. The IRS will break before the ZF will.
My dad has a 90 C4 with a big block and ZF that produces 639 LBS FT# torque. He has never had a problem with the transmission.
