    Unhappy 1988 transmission diagnose help

    my 88 allante ive had for three years, its not a knockout broad but it has teeth, lol anyways lately it will not shift out of 1st, itll just rez with no traction, last year it would have to warm up 10 to 15 mins before it engaged 1st gear, then all of a sudden it jumps into gear seconds after placing shift into gear spot, reverse has always worked, now i cant drive on highway

    also when i turn car off and crank back it takes off fine, but still wont shift just revs up no speed

    I presume you have checked the transmission fluid level? You should check with the engine running in park, there is a hot and cold mark.

    The first to second gear shift is controlled by a cable that goes from the throttle body to the trans. i would have that checked first.
