Letat lite på nätet ; de flesta verkar ha problem med vacuum, men hittade en med något som du kan kolla
http://www.jalopyjournal.com/forum/thre ... ar.470242/OK, I figured it out.
I bought the modulator during the day when I was out of the office running around. I installed the modulator, but then when I had the car up in the air I decided to go ahead and pull the governor out again and check that the calve inside it was sliding in and out with the weights and it was not! So I used a small screw driver to give it a nudge and it finally started moving. With a little ATF it began to move freely and easily.
I took it for a quick drive around the block and it was shifting!!!!!! YAY!!!!
