Sounds like you may have crap in the valve body, about the only thing possibly to try before disassembly is a tranny flush.

Thanks to all who answer my original request. Taking your advice, I checked
the selector.
All  OK there. Dropped the tranny pan last Saturday. There were no debris
present. The fluid
was clear  though slightly dark with a mid burnt smell.The filter appeared
to almost completely
blocked so I figured I had the problem in  hand. I inspected the visible
parts and all seemed in
order.

Fluid from the torque was also devoid of any debris.

After cleaning the pan and buttoning the tranny up, I installed new Mobil1
atf. Fired up the car and..
no change.

Still no forward or reverse at any rpm.

Are there any further thoughts?

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
