The sender switch is located in the lube pressure port. Normal lube pressure should be about 20 PSI.
TA lube uses oil left after the steering, brakes, and TA control. This oil floe is regulated to about 20 PSI with the remainder dumped to the reservoir. With the clutch pushed in the TA control pressure/flow is dumped to reservoir to release both clutch packs so there is no flow available to the TA lube circuit.
When adjusting the dump valve what you want to see is as you push the clutch in the tractor movement should stop before the pressure drops to zero. When releasing the pedal the pressure should return to normal before the tractor starts to move.
If the low side of the TA works this adjustment can easily be checked without a gauge or light. This method also works on the older/smaller mechanical TA units. It eliminates having to make any measurements and compensates for worn linkage. The measurements in the book are to give you a way to adjust things sitting on the shop floor. Using the following procedure will insure that the adjustments are made to to get the linkage to work as it should.
Face the tractor up hill, enough that it will roll back on it's own. With the TA lever forward and the tractor moving in first gear slowly push in the clutch until the tractor stops moving forward. At that point the TA should keep the tractor from rolling backwards. Pushing the clutch pedal down a little more should allow the tractor to roll backwards and you should be able to shift the transmission. To check the adjustment while releasing the clutch pedal, again with the tractor in low and TA lever ahead, the tractor should stop rolling backwards and then releasing the pedal a little, the tractor should start to move forward.
