Hey everyone,

I just purchased a 92 Firebird 5 speed and it actually came with a four-speed Borg Warner Super T 10 transmission. I am racing the car and the class I am in requires the stock T5 transmission. Does anyone know if the super t10 and t5 transmission uses the same crossmember and the same length driveshaft?

Also if anyone has a freshly rebuilt t-5 I'm interested in purchasing.

Thanks
John

 

Yes we do; and no they do not.

Hard to say what you'd have to do to go back to a T-5, without knowing how the T-10 was hacked into the car. FOR SURE, the crossmember, drive shaft, and torque arm (or its mounting, or even its presence) have been altered in some way; and most likely, you'd also need a bell housing and clutch actuation system as well.

The devil will be in the details.

 

OK thank you very much. Could you please post some pictures of the T5 crossmember and I can compare to what I have.

 

Pictures aren't real informative.

Get up under your car. There should be 3 bolt holes in the "frame" for a crossmember. Your T-10 crossmember is probably bolted to the front and middle ones. A T-5 one bolts to the middle and rear ones. As you lay up under there, won't be hard to see what the problem, or rather the opportunity for a solution, is. (or isn't, if you're lucky... don't bet on it)

 

Thank you for the help Sofakingdom.

Can anyone point me to a source that can sell me a freshly rebuilt t5 transmission for the 92 Firebird?

 

They pop up in the classifieds every once in a while. I got mine from a member here. Cost about $70 to ship from texas to NY I would check with

Take a bunch of pictures of what you have we can probably help a lot more after.

There are also always a few on ebay
