743 trans. light still on

[gary44]

My 743 has a square block on the pump. I checked the fluid it is full. How would you check the trans. presure? And what should the presure be? Also the oil presure- temp. light comes on at low idle after the machine runs for awhile. When you speed the idle up the light goes out. The oil presure never goes below 20#.Any help would be great. Thanks, gary44

To check the pressure you remove the sender from the block and install a pressure gauge. It should be 90-120 psi. Have you replaced the hidden filter on the left side of the port block behind the middle fitting? many people miss it.
