manual rheostat instead of TPS for automatic transmission control?
I've got an idea regarding a computer controlled automatic transmission - a manual potentiometer
I have an Allison 2500 that I want to swap for the AT545 behind a carbed 454. There is no TPS on the carb, and I don't want to add one.
What if, for the TPS input to the computer, I hook up a manual potentiometer and put it on the dash?
So, when I want it to downshift and change the shift points to high RPMs, I slide the potentiometer up to imitate full throttle. Coasting on the highway, slide it down to indicate low throttle. Then I can have more control of the shifting. I can make the computer think I have it floored if I wanna run higher RPMS at low throttle. I can make the computer think I have it at low throttle and not downshift if I want to lug the engine. Or somewhere in the middle.
Would this work?
