What are the Torque Convertor pressures?

    The outlet pressure should be around 60Psi and the inlet around 115Psi. You only get the inlet reading upon start up with cold oil for a few minutes then it will drop down to around 10 Psi above the outlet reading. Are you having an overheating problem? Later Bob

    Yes, after about an hour it heats up and loses power.

    Check the priority pressure with warm oil at high and low throttle, first in neutral then hold the brake down and in all gears at low throttle. Repeat the test again with the right and then the left steering levers pulled back. Then again in neutral with trans lockout lever up. Come back with results. Later Bob

    Torque converter outlet relief valve pressure setting is "approximately 42psi" according to the manual.

    Is the S/N of the machine above or below 4000..? There is a S/N break at that point which may or may not make a difference to specifications, test & adjust procedures, etc, etc.
