i am building up my 86 T-Type and had the trans done by a local shop with a good rep, they did some of the performance basics. Other than the lock-up not working (a question for another thread...), i have had no problems with it.

i'd like to know just what the trans will take. i want to keep the OEM trans because i do drive the car daily (i just love driving it!).

thanks in advance.

That's a tough question to answer, without knowing what has been done to the tranny. If it has all the good stuff (billet pieces, good clutches, pump, ect), I would say 9's are possible but you would be asking alot from the tranny. If you have a good stock rebuild, I would not try to push it faster than the 12's. If your lock up is not working, and everything is not up to snuff, have the trans guy get it right.

Thanks for the response. The trans has HD clutches, billet servo, shift kit (trans-go) and the stock pump. the convertor is 2800 LU. I took it back to get the LU working again and they got it working - i stored the car and when i brought it out last year the LU didn't work again, so i'm currently trying to figure that out. The goal for the car is low 11's, but i'm not opposed to a solid 10 sec run! do i need a different pump for that? any other 'must-do's' for the trans? (other than the converter, of course).

thanks again
Matt

I would look into a billet forward drum minimum. I broke mine twice, once when shifting into second gear, once by locking the converter at WOT. (one of 100 times I did that lol)
I went with a 9.5" PTC N/L converter and it revs at about 2000rpm at 65 mph, not much different than a locking one.

We carry them, let me know if you want one, those are a non LU converter, but tend to couple much better than older non lu units..
