D6H transmission has zero lub pressure
Here's a picture inside the rear pto after removing the inter and outer races of the rear bearing, All balls where gone. The gap is between the case-as and carrier-ring. So this at least one place I'm losing pressure. -

D6H transmission has zero lub pressure
Thanks, Preparing to pull the transmission. I'm thinking excessive wear in the transmission may be causing some of my low lub pressure. When I was playing with the shims in the priority valve and got the converter output pressure to specs, the lub pressure was still about 70% low. Does this... -

Yes, I'm measuring trans lube pressure at tap-D. Do you think the pump's input filter is contaminated enough to restrict flow to lower pump pressure? -

Thank you Nige for your input. Here are the pictures of the input filter to the pump. Did not find a screen in the line coming from the torque converter. The listed pressures below are with the dozer cold but pressures did not change with a transmission oil temp of 80 degrees C. With the belly... -
