I am not an automatic guy, but thats quite interesting. What do you do for making the speedometer function? I imagine that you will need a driveshaft with a slip spline in the shaft. I have seen newer vehicle that some have that in the front section, others in the rear. Not sure if that matters one way of the other, just curious. Do these have transmision dipsticks, or are they closed transmissions that require special procedures to check & add ATF to?
