Hey everyone... been having transmission issues for around a year. Vehicle goes onto "limp mode" (re: stick in third or fourth) pretty frequently. Issue goes away after vehicle restart. Seems to occur more when going over large flexed bumps or on longer bumpy roads.

Multiple shops checked and have been unable to resolve so I'm looking for an electrical specialist in the Sacramento area. .. any recommendations?

We've already:
Replaced 3/4 solenoid
Checked wheel speed sensors
Removed TrailDash and reflashed TCM
Checked "standard" electrical perfomance and connectors
