I just had a 7130 speed transmission apart to replace the speed input shaft. I did reseal the pistons for the odd/even clutch packs. I got the tractor back together and moving. the tractor really isnt wanting to move in reverese. I installled gauges in all the test ports. My master clutch pressure is running around 170 psi. my regulated pressure is right at 270 psi. when I go to put the tractor into r1 and r2 the high medium low gauge drops to 0 psi and the tractor wont back up. Driving in forward gear gears all my pressures except master clutch are around 250 psi. I know my clutch cable and fnr cable arent quite adjusted right but I think its close enough it should be able to read the right pressures. Any ideas if I have a leaking clutch pack?
