i have a 02 that has ran fine its whole life at 310,xxx i finally decided to do headgaskets. i let the shop do the job(sinister gasket and arp2000s kit) and got 1200 miles out of it and it completely shut off and locked up on my wife. Thankfully she was only doing 20mph and was able to safely pull over. didnt happen under heavy acceleration, no smoke from exhaust, no noise, no nothing just shut off. I went to where she was on the side of the road and sure enough it acted like bad starter or dead batteries, checked belt, checked voltage all good. i put key in on position and crawled underneath to jump starter and i could hear the bendix come out but no crank. towed it home and put a breaker bar on the crank bolt and all i did was tighten the crank bolt (didnt move either direction)Any ideas? ive read that its possible for the pump in the allison to fail and lock up input shaft but at this point thats wishful thinking.
