Transmission Oil Leak
My 928S is a 1981 model fitted with the 3 speed Mercedes automatic
transmission. I have fixed numerous transmission oil leaks but have
one that to date I've been unable to fix. Seems to be leaking from above
the anti restart / backup light switch.
I've replaced the seal on the backup light switch shaft but still no luck. Looking at the manual I believe there to be an oring that seals the pressure unit b1 or in that general area.
Has anyone had a similar oil leak in this area? If so is it possible
to remove the b1 pressure unit by just removing the control valve body
assembly from underneath the transmission or does the transmission have to be removed from the car and
be dismantled ?
Appreciate any assistance
