TH-400 in a Vette! Who has done it and what was involved?
If you were to do it all over again would you? Is it worth it?
Does anybody make any kits for our cars, if so who?
Thank You,
Paul

You may wanna hitup Vette Doctors. I know some of their cars have had T400s in 'em. There's a member of the forum named Major Spray who Im fairly sure had a T400 before a 4L-series trans.

Rossler also has a 4L80E which has been known to stand up to many low 9-high 8 second passes. Call Jason up at F-Body Central in Baltimore, he put one in a FRC with a 43X inch C5R motor for a guy named Calvin I think...he'll let you know what you need.

I just got off the phone with Yank. They have everything needed. Its around $5400 but as much as I will go through clutches and the time the car will spend down I think its plenty worth it and will pay for its self illegally!

Glad to hear it! What kind of power do you plan on making with the car?? I have heard that Cartek has several high 9second auto Corvettes still running the 4L60 (4L65) with cryo-treated hard parts and the usual upgrades. It robs a bit less power than the -80 does, and can be made to withstand pretty good power, especially in a car like the Vette.

For the amount of power you are talking about therre is no reason you can't get a 4l60 to work. I will be testing the yank system again real soon if we get the bugs worked out it is diffenatly the way to go with for the big HP cars but I am talking 800 plus. To install the yank system you need to modify torque tube /tranny tunnel it is a bit of a under taking. I wouldn't go through that in your case.
Good Luck
Paul
BTW I had a custom built by The Vette Doctors 4l60 in my car all last season running 9.3 - 9.5 @ 149mph

There are special shafts and adaptors that are needed and all of the parts will have to be custom made there is not a market for a volume of the kits to keep the production cost down.
We are still looking into offering the redesigned 4l80-e kit if the market wants it.
The big draw back is that the body and frame wrap up on launch and with wrap up the torque tube winds up misaligning the drive line
so a full cage must be installed to stop this twisting action on a drag race car.
The new 4l80-e kit will stop this wrap up in the drive line but it all comes at a cost in the conversion kit

4l60. He sent it to a tranny shop here that does performance internals and its keeps eating up converters. I dont think he has it run smooth yet. He spent a lot of money and is fed up with it. he has has it done on a 2002 Ws6 with 150 shot and bolt ons.

Do you still offer the 400 swap? I didn't see it listed on your site. What price range are we talking about to do the 400? I am interested in doing the work myself. Primarily I am looking for the adaptors nessesary for me to fit one myself.
Rossler makes a 4l60e for the C5 that TEA uses in their project car. That is a more than full weight C5 coupe with roll cage, full interior, working A/C and stereo and has made a 9.87 second pass @138mph .Its a $3000 expense that you might look into.Here she is ready to be installed.

We still sell the 400 kit and all the parts per item.
there are many options so cost can be about the same as a built 4l60-e to as much as you mant to spend
call me for info and pricing
