Thread: Just how much...

I know the stock can't hold up to much lower than 13's but if I were to buy a race tranny how far will it hold up without having to constantly drop and repair parts? Don't want to have to keep repairing trannys with my build, might just have to find a lighter car to swap it into if the trannys are actually that bad.

I live by the go big or go home, so I plan on pushing max hp and torque that you can with the M90 and hopefully still have it as a DD so it has to be able to hold up to the track and be able to drive down the street without it failing lol.

upgraded clutches, input shaft, hardened 4th, tc stalled below 3000, 7/8th single chain and the extra few modifications that all good 4t65E tranny rebuilders do.

The stock tranny has gone to 11's but has also failed in the 14's, just depends.

Most people go with the 7/8's over the 15/16's why is that? And if I could find a 1" how long would it last me into?

I think the availability of the 7/8ths although i never really looked at that. The 1" has never been broken and would probably last forever but it is going to be $1000 since they stopped making them and there are only a few left.
