    Speed Sensor

    Steady throttle/low rpm cruising @ 20 MPH the tranny will buck and slip a little, are these symptoms of a failing speed sensor (my friend suggested thats what it was and I've never heard of one before)

    Mine does the same thing, going soon for WDS test at the dealer, usually from what I understand from members the test is 100.00, my dealer charges 69.00. I really think it's one of the coils. We will see................

    Are you sure it's the transmission acting up? That's a strange failure mode for a transmission...
