If transmission pump flow is good, then I would remove the pressure control valve (priority valve) to see if any of the metal shavings are trapped there. Then flush out the line between the pump and pressure control valve before installing new pump. Click to expand…
What causes a backhoe to lock up in reverse?
2) The belville washer in the forward pack breaks into pieces (due to heat or excessive clearances caused by worn plates) – this often causes the forward pack to sometimes lock up permanently, so when reverse is selected the transmission locks up trying to drive in forward & reverse at the same time.
