    Is there a bolt in 4 speed auto for a 1980 3/4 ton 4 x 4 with Turbo 400?

    Easiest option would be a 700r4. It may require a different t-case and lengthening your driveshafts.

    I guess there is no truly bolt in replacement. I have a NP 205 I think with the turbo 400.

    Well there is a 374 in the 1990's I think can't rember for sure, all it is really is a computer controled 400 you would need a wireing & computer & that trans . So it sort a like two evils price wise, most like better with the 700R4
