    What is the stall speed for a diesel version torque converter in a TH400?

    Thanks

    I would guess around 900 but I don't bother much I just ask for a diesel TC /forums/images/graemlins/thumb.gif

    Well, I have a gas motor now and was wanting to compare the stall speeds between the diesel and gas converters. If the gas is a good deal higher I think I will replace the converter will a gas model for better take off. If they are close I will just stick with what I got.

    I think they are about 200-300RPM's difference

    Do you think that is enough rpm to swap to a gas converter? My take off is not that great now and I was hoping this would improve it a great deal. I don't want a race converter but something close to a stock gas converter.

    You will feel a difference, but I can tell you that heat is going to be there because the working RPM's for your diesel is around the stall speed of a gasser, so you better have a very good cooler.
    Since it's a 400 you might be able to make it work, but I can't tell you for sure.
    If you feel like working on it a couple of times, try swappint the converter, and drive it for a couple of days, but be sure to instal a tranny temp guage, and see if it slips a lot and if the temps go up too much.
    It could work.
