83 300tdt trans
 

Have 83 wagon 200k with auto trans problem. Everything is O K until you get on it from standstill, then its like it went to neutral. Can this be linkage out of adj. or something inside. I have changed filter and plugged vac. line from modulater, no change.
Hope someone has a solution without a rebuild. It gets scary pulling out in traffic.
Thanks in advance, Paul

I don't have much good to add here but it seems like I've heard of about 6 of these cases in the last month or two, perhaps I should research this as I just keep seeing it pop up.
