OK I have a 85 short step 502/th400/411s I bought it in march with a bad trans. I went and bought a new trans put it in and 2000 miles later i cracked the case well the bell from about 4 inches from the starter by the cover up and around. Its got a warranty so not to mad about it but should i just slam a new one in it or should i try something new??

I think you need to determine why the trans cracked before you put in another one. Otherwise it could happen again.

well my trany guy seems to think there was a crack in the case. and he was making fun of me because i had to get the reman and not rebuild the one that came out of the truck. All looks good under the truck so i have to think there was a hair line crack that got missed by me and the factory.

ok so bad news for now i will know tomorrow if it covered because i put it in my self. so what do you think of j.w. ultra bell bellhousing if its a no go?

An ultra bell/scatter shield is an excellent piece of preventative hardware, ask Don Garlits. You are real lucky that thing didn't come apart in a bad way!! You can have the guts of the th400 w/cracked bell put into another case, won't be free, but should be cheaper than buying a complete new 400??

BOY, does this sound familiar. (cost me a $1000 tranny)let me guess. is the truck lowered?? especially the back? crossy

no stock stance and drive shaft is good

**crossy** · 05-28-2009, 11:01 AM

OK, but i would have the pinion angle checked and make sure the driveshaft yoke has ample 'slide in' distance. i found mine had this tranny history after i broke the case. Due to PO being a butcher. I never got over it due to the work now involved. good luck. crossy

hotrodders and racers have been using torque straps to keep an engine in place and prevent failures since b4 WW2

Crossy all that is good I checked it when i got it because of the PO going thought 3 transmissions in 10k miles(he was putting bolt on yoke th400s in it with a one piece drive shaft) Thats why i think there was a hair line crack in it

I had th400 do the same thing You could see where it had been cracked for a long time and the the fresh break.... Might just be a th400 thing... or maybe one to many reverse to drive under full throttle i dont know... a friend off mine that worked in a tranny shop said he had seen it before in hardcore 4X4s a few times... I dont think its anything to worry about.... just one of those things
