Hello,
I have a 1992 190e 2.0L which has stopped engaging reverse gear. It has only travelled 60k miles (100k km) and is strong in all forward gears. Reverse gear has engaged intermittently since failing and on both occasions has been also been strong. As a result it seems that the problem may not be within the drive train of the gearbox itself but possibly with the switching mechanism or valves.


I hope that the problem will be solved according to the attached technical note which points me to the valve body, however, I have been unable to find the required part numbers and am wondering if anyone out there can help with part numbers or another suggestion as to how I could track them down.


The parts are called;
"Accumulator Switching On Control Valve",
"Accumulator Switching On Control Valve Spring",
"Accumulator Switching On Piston seal ring"
"Accumulator Switching On Piston"
These parts are shown in the attached diagram.


The transmission number is 722400 0 3252557.
Any assistance would be most appreciated.
