A while back I had a problem with my TH350 no shifting out of first, a quick governor gear change and I was back on the road. Now its developed a new problem. I have reverse and 3rd gear. Tranny will not automaticaly shift back down to 2nd or first. If you manually pull it down it to first the vehicle will not go and locks right up like i slammed it in park. It doesnt feel like its in park when you try to go it more like your trying to power brake it.

At first I thought governor but if it was screwed up wouldnt it just stay in 1st gear like when the gear was shot?
