I have a problem with my 85 300SD transmission that I would like to explore. The transmission and torque converter were replaced in Oct 2003. It has logged 30k miles. I bought it from Rusty. It is filled with Mobil1Synthetic fluid .
It has been performing flawlessly until recently. In the past few weeks, I noticed the forward shifts, all of them, where harsher than in the past. I attributed this to vacuum and made a note to go over the vac system soon. However, yesterday I parked the car and made a quick dash into a store. I returned to the car, fired it up, put it in drive, but the transmission did not engage. Not forward or reverse. Revving up the engine makes no difference.Fluid level fine, nice and pink. Other than the harsher shifts, there were no other symptoms, sounds, on-the-road problems, or fluid leaks. It simply stopped working. Does this sound like a valve body seal problem? Maybe a bad torque converter? Modulator? Regards, Bill Phelps Annapolis, MD 85 300SD Beeker 85 300SD Parts
