Like the title says, I was wondering if there was a way to lower the part throttle shift points of an A500 trans. The trans is in my 78 Fury, and Im using the same throttle pressure linkage and lever as the 727 that came out of the car. The trans always winds out to at least 2000rpm before shifting, no matter how easy you are on the gas. The stock 727 used to shift at around 1600 under the same conditions and rate of acceleration. At WOT, it is perfect at around 5200 or so. The trans is all stock with the exception of a blocker rod in the accumulator, which obviously wouldnt change anything. Its just more of an annoyance than anything, since theres no real reason for it to wind up so much before it shifts, and Im sure its affecting gas mileage. Ive played with the TP linkage and it will shift at the same points at part throttle, but will remove firmness from the shifts if backed off. Do I have to change the weights in the governor to accomplish this? The trans is originally out of a 95 3.9 Dakota. Is that just when they shift? The 46RE in my 2000 Dakota R/T does pretty much the same thing....maybe a few hundred RPM lower, but not much. Will 904 governor pistons/parts interchange since this trans is based on a 904?
