    Late changing / gear drops and engine over revs

    Hi All. Having two issues with my 94 Limited.

    First issue is it does not upshift at correct revs, ends up revving quite high and I have to trick the transmission by blipping the throttle and it sometimes changes then. This isn't a major issue for me.

    The real problem is when I accelerate hard and it drops a gear it's as if it doesn't select a gear and the engine will suddenly over rev. If I ease on power it's fine only when it drops a gear.

    Have carried out a gearbox fluid refresh and my mechanic spotted a vacuum hose on the transmission that was off but he reconnected. Does not seem to make any difference.

    Would he greatful to hear any thoughts. Hoping the transmission is not coming to the end of its life.

    Thanks.

    First thing I'd check is the fluid level, must be checked with the trans hot (20+ mins at freeway speeds)... next item is to verify the Bowden cable (control pressure cable) is adjusted correctly.

    What you describe about the engine "over revving" and trans not selecting a gear sounds like the transmission is flaring / slipping.

    CHECK FOR A STUCK KICKDOWN SWITCH UNDER YOUR GAS PEDAL AND CHECK THAT YOUR "B-POSITION" SWITCH IN THE SHIFT GATE HASN'T BEEN PUSHED INTO THE "B" POSITION. IF BOTH ARE OK, TRY DRIVING IT WITH THE KICKDOWN SOLENOID AT THE RIGHT REAR OF THE TRANSMISSION HOUSING UNPLUGGED! YES, I'M YELLING!
    SORRY...

    OH YEAH! CHECK THE KICKDOWN CIRCUIT TOO, AS KLINK DESCRIBED ABOVE (UNPLUG WIRE AT TRANS TO TEST).

    (sorry, couldn't help myself, lol!)
