I am going on what my mechanic said...here is his email

"I checked vacuum at modulator and have none, I do have vacuum to the valve at the top of injection pump.
It stopped there. I checked the valve with a mini vac (hand held vacuum pump and the diaphram does not move). It has to have a hole in it. See if you can find this vacuum diaphram because I believe that this is our problem with the shifting."
Anybody help further? car has vacuum and brakes and doors lock.
Thanks to all who are trying to help
