My buddies just installed a 3400 stall with a heavy duty shift kit and tranny cooler. Also put some longtube headers. The car has ls6 intake, 373's, and full exhaust now. Getting tune tomarrow. How will the tranny hold up with these mods?

 

properly tuned, it will last for a while. Depends upon how many miles and how abuse it has already seen.

 

I have a 60e that was rebuilt with a shift kit and has a 3500 stall hanging from it. Its got about 15k miles on it and probably 25 track passes. It let go last sunday, no 3-4 gear now. Debating replacement options now.

 

it will last exactly 12k mile...






too many variables to consider but as long as you dont beat the crap out of it, it should last awhile. some peoples last forever, some crap out in a week. i beat the **** out of mine and it never broke, the only reason i changed mine was because the motor was out and it was a easy time to do a swap.

 

Depends if it sees the track. I wouldnt pout a 60e in my car cuz how i drive. I like to floor it.
