hello and thanks for donating!


have you had any previous transmission or engine work done to this vehicle recently? it may have the wrong ECM to TCM matching if one or the other was recently replaced. if not then you should inspect wiring to the ECM and TCM, check for pressure loss in the valve body as well as for mechanical component failures, incorrect rear axle ratio, and the ATF oil filter to ensure its installed properly.
