I wished I could help you out. I guess that's why mine is hard to find 1st gear or reverse. I believe I need a 4 speed front to back top to bottom inspection on my trans. Someone with a lift and knows WTF they are doing. I will let a mechanic I trust look at it on his lift, give him the keys and tell him to call me when you get it shifting like it suppose to. I have had enough trying and actually just don't have time.
I will be watching this thread however.
