Jumps out of gear and "Gearbox Malfunction" appears on dash. Sometimes works for a little while before this happens.
Scanned with VCDS and I am getting 20888 - Pressure Control Solenoid 1 - P0748 error.
I have replaced the ATF, motor, filters and all the solenoids.
Does anyone have any experience with these.. could the TCU be faulty or is there another hardware element within the ATU which could be at fault.
