Ive got an '85 blazer w/ a 6.2 and a 700r4. I recently replaced it and the tranny mount with a "bulletproof" trans and shortly thereafter, the (grade 8) bolt going throuth the t-case support rod/bellhousing into the motor started breaking. I managed to get it out and replaced it. It broke again and whilie I was nursing it home from work (>5 miles) the new one broke too, then the upper pass side trans-motor bolt. Just as I was pulling into my parking lot I heard the rattle. When I crawled under the truck I found that the only remaining pass side bolt had held out, but took off a chunk of the bellhousing about five inches by three inches. I warranted out the transmission for a new one thinking the case was weak. I installed the new one and after a few days, the same bottom pass side bolt popped. Again I replaced it, again it popped, and again the bellhousing broke. I tried to warranty out this one and the company I bought it from voided my warranty. If anyone has had a similar problem and found a solution, I would greatly appreciate any advice.
