I imagine there are likely to be other parts that have been changed to meet with design criteria for each model- not just torque et al.Originally Posted by Frank87;349820[COLOR=#333333
Is the clutch pack the only difference with the entire assy part for these models? You may need to trawl through the exploded parts list of each different trans part number to see. I would expect many other differences- particularly in the valve bodies, and more if an extra disc is present in the clutch pack.
Such as smoothness and delay time engaging gear, weight of the vehicle, warranty differences. If an extra disc in the pack spreads the friction load or increase the pressure on the other disc, or is it for longevity or ability to handle power? Sometimes just region/market differences result in different boxes being used.
Maybe someone else can be a better help, and give you something more specific/better hints
