No movement in reverse, OD,D,2,1 91 explorer

[adeelregina]

By the way, what will I diagonoze by hooking up the oil pressure value, because I already spent like $200 to buy this kit and like 2 hrs trying to install it... I am getting a used transmission for like $650 with 76K miles on it, so maybe I would be better of buying the used transmission.

Has I had mentioned I already had my value body changed like 3 months ago, and ever since I was having the reverse problem when the car was hot. And then later on All the gears wouldnt engage.. I had bought this rebuild A4ld from Ebay? So I am curious whether it could just be a value body issue or something else...

Please guide me

The pump could be bad if you have extremely low pressure, or no pressure at all. RPM controlled line fluctuations could point to sticky valves or spools in the valve body or end plugs. The boost valve could be sticking, or there could be clogged bores in the valve body limiting the line pressure. Sometimes the pressure could appear to be normal at idle, but it won't stay high when you rev it due to valve body issues.

so that means if I can hook up the oil pressure guage this would give a better idea to see if the value body is faulty or something else right
