I do know what you are saying. Although, the popular opinion with many rebuilders in this area is the '03-'04 4l60e is probably the strongest version of the overdrives built. This unit in my truck failed during half throttle acceleration-half way through second gear at about 40-45 mph-if thats worth anything. The repair bill will probably die a slow death in my checkbook register.

So, back to my question-what has everyone else broke and any suggestions for upgraded hard parts?
