I've been reading a lot of the discussions about running automatics TH350;s, in 1st or second gear. I used to race a street stock on a 5/16 mile dirt track. Blew up two of them in two nights. Put in a 3spd manual and never tried again.

Now I am looking to get back in where I live now, and several of the tracks mandate an automatic. How are you guys getting a TH350 to take 6-7 grand without blowing up?

There is no secret. A decent tranny cooler...that's about it.

All i have is a steel tranny line looped in front of the rad and i turn mine 6000 in second, my buddy turns his 6300 in first with a single loop tranny cooler....i've been running the same tranny and setup for it for 3 years now and my buddies been running his that way for 2 years. And these trannys are stock...not rebuilt or anything....they were the ones that came in our cars...with prolly a million miles on them lol.

I guess I'm just lucky too -- I ran the ol' TH350 that came in my first Metric car for three or four seasons without any problems, and that car came from a kid who was drivin' it to school all week and drag racin' it on the weekends.

Keepin' it cool is definintely important, and be sure to check it out after crashes because impacts or twisting of the frame itself can break that little mount off the back part of the trans pretty easy - which can let it get bound up like nobody's business. I've used up several of those rear trans mounts -- but what finally killed the first transmission I ever used up was backin' it into the turn three wall at speed ~ trans guy says it "exploded" 1st/reverse parts... Apparently transmissions just don't like catchin' that wall at throttle. heehee!
