These Sensor are only about $15 - $20 each and I would suggest replacing these first to see if they fix you problem. Also have you checked the tranny fluid? If so what color was it and did it have a burnt smell to it. If so then I would try a tranny service. Change the Fluid and filter. Another posibilities is the Transmission Control Computer (ECAT Control Module) Located on the passenger side firewall near the strut tower. Or the ECAT Selenoid Pack check pic above for location. .
