GLE 550e fault code P084000
My understanding is that it can be triggered by either 1. A faulty electronic pressure control solenoid, 2. contaminated and restricted transmission filter, 3. blocked transmission orifices, or a 4. faulty PCM or TCM
With all the possibilities listed, I cannot find a way to pin point the exact cause of the fault, and if I am to exercise an approach of process of elimination, it potentially could be repetitive with having to go in and out of the transmission and very costly!
I am hoping that others might have experience this fault and could share their experiences and approach to solving for the fault code.
