Sleepless, nice avatar! But to answer your quote. GM makes the 3.0 trannies. And ZF for the V8's. To be honest, I've heard a lot more GM trannies going bad then ZF's. But again this is he said she said stuff. There is no explaination about why they fail, but sure you not, both trannies have a great possibility to fail at anytime. My thing is when people use the manual shifting. I think that's where trannies begin to fail. Just my opinion.
