T400's are stout, it'll hold up no prob, if it's in good shape. The only real difference between a truck trans and a car trans is the calibration -- shift points. Put a shift kit in it, and either change the governer, or get a B&M kit so you can adjust it. The governer works like the mechanical advance in a distributor, and controls WOT shiftpoints. It's behind a round plate on the pass side of the trans. The truck trans will shift at real low rpm at WOT (even if you hold it in low gear).
