    jumpy could be wheel hop related to an uncorrected pinion angle

    2nd on angle...


    check fluid level too...mine did that when it was lil low (tightened up cover, refilled, been good since)
    blown transmissions are about as useful as 97% of the guys on this forum

    fix the angle either with shims, or cutting and re-welding the perches, should be about -4 or -5 degrees

    Warranty might not fix a pinion angle change due to aftermarket parts, lol.
