hi i'm new here and would appreciate any help, i recently started having problems with the transmission on my 97 escort SE. it all started 1 day i was driving into town and the transmission stopped working at a stop sign. i pushed it out of the way and turned it off, after restarting started working for about a minute then it went out again. after letting it sit for about an hour once again it started working but this time longer. this process kept reoccurring and getting worse. after changing the transmission filter and oil it seemed to start working normal again but after driving a short while the problem started again this time while driving it would slip out of gear and wouldn't move unless i restarted it. any idea if it could be a sensor or is it sounding like its time for a new transmission?
