Anyone have any experience troubleshooting an AW55-50/51SN Transmission? Issue is transmission sounds like it is building up high pressure when at a stop but in drive. It's almost like the torque converter is trying to make the car move more so than it should. Makes whole car rumble. As soon as car starts to roll, pressure settles right down and rumble is gone. Shifts are mostly smooth. Slight surge when shifting from 1->2 and bump when downshifting from 2->1. I have tried a relearn procedure through VIDA and that made no difference. Do I need to adjust main solenoids in valve body? Or should I just replace them with Rostra, or Replace whole valve body or replace whole transmission? Thanks for any help or ideas you can come up with.
