I remember doing the road test with Tom checking the shift point, but don't remember talking about the overdrive. On my extended trip to ky and back, I noticed that it was hesitant to go into o/d, and would pop out of o/d randomly. Are o/d parameters something that is pcm controlled, or is it possible there is a mechanical problem?

I should note that there was no slipping or other problems, just didn't want to drop into o/d sometimes, or would pick a random time to do so....It really liked popping into o/d under load up hills, wtf.
