    I have a 6.2 diesel in my 92 flat bed and I want to install a turbo 400.
    can anyony tell me the difference with diesel and non diesel transmissions and what should I be looking for?
    Thanks Cliff

    There is no difference between gas and diesel . Only if its 4wheel drive is there a difference on transfer case spline count and such.

    Aren't the valve bodies setup differently so the diesel can shift earlier? I wouldn't want to do a full throttle upshift in a 6.2 at 5500rpm!

    I was told there was a diffrence in tranny's because of the RPM diffrence.
    if there is a diffrence would it be in the gearing or in the valving? and could a gas tranny be converted? thanks for responding. Cliff

    A diesel does not rev as high as a gasser, therefore the shift points have to be lowered. The convertor may be a lower stall speed too, not sure.

    I see no reason why a gas tranny couldn't be recalibrated or have the valvebody replaced entirely with a diesel unit. The internals should all be the same.

    Ideally, you would just start with the right tranny in the first place.

    Talk to people at a tranny shop (a KNOWLEDGABLE one, not one that specializes in just stock rebuilding or exchange), see if they know more about recalibrating it. I would imagine the valving and body itself are identical, just different tension springs controlling it.
