1994 Ford Econoline v-8 shifting

i also have a problem with the transmission. it will act as if it shifts to neutral when going to overdrive. I have changed the throttle position sensor and the problem got better but now is acting up again. Could this be a sensor on the transmission?

Some of this era had some elect. wires going to trans, maybe electronic shift, there is a connector that allows moisture in and causes problems like that. There is a TSB somewhere about it, and I think Ford replaced the connector free at one time, I,m sure that's no longer true, but should be able to get one from Ford dealer. Have them look up the TSB. Good luck
