Hi. I'm still having shifting problems with my '99 with the 4R44E auto trans. It will not go into D after shifting from R or P but will engage if I first shift to ! or 2 and then to D. I have adjusted the bands 1 1/2 turns out. Someone said two turns but at least two other sources said 1 1/2 so I went with the majority.

Anyway, I found a "tip" on this particular trans that said turning the Force Motor (aka pressure control solenoid) 1/2 turn in should improve my shifting. Can someone tell me where it is and how to identify it? I assume it's inside somewhere.

Thanks.
 
It's called the EPC solenoid and it's the largest one on the left side of the valve body.
