Okay, I'll explain the situation and the outcome.
I have a 91 350SD that I just pulled the 3.5 out of and put in a 3.0. Just got it all hooked back up on Friday. Fired right up without hesitation. Let it run a little added fluids as it started warming up. Got in put it in drive went forward, put it in Reverse went backwards...did this a couple times. Checked the transmission fluid while it was still running, a little low so I added some, maybe a tad above the full line. Got back in the car (it had never been turned off since I was driving back and for the and then added transmission fluid) put it in drive....nothing, revved up the RPM's, no movement. Put it in Reverse....nothing.
If I put it in Park the transmission goes in Park like it's supposed to, when I put it in Reverse or Drive there is no engagement and I can roll the car like it is in Neutral.
I did not replace the transmission or adjust the Bowden cable when I removed the old motor. But I don't suspect the Bowden cable as I drove it back and forth in the driveway with no problems and now nothing.
Any suggestions or ideas?
