After testing T got: trans oil pump pressure 28bar speed pressure 25bar direction pressure 21bar the modulation is shifting as expected when changing direction and speed converter inlet presuure is 7bar neutral and high idle (2400rpm) at 45 degree C converter inlet pressure is 5 bar Rvse 1 and high idle (2300rpm) at 45 degree C Is it torque converter leaking making the machine slow in travel and without power when digging?
