hello, I have a L322 3.0L with the GM 5L40e gearbox
my problem with the automatic gearbox: in neutral position, the car moves forward as if 1 were engaged. And in position R, I feel a tension in the gearbox but the car remains motionless.
No error code on the gearbox ECU.
I have disassembled the valve and solenoid control unit. I completely dismantled and cleaned it. I didn’t see anything in particular. After reassembly and new oil, same problem.
An idea to help me.
PS : sorry for my english, I'm french...
PS2: sorry, I made a mistake in the title of this discussion, it is the GM 5L40e gearbox and not GM 5L50e
