white 140

cjb138 · Jul 9, 2015

I have a white 140 and the transmission lube light and buzzer will sound when I activate the hydraulic remotes and after warmed up the light and buzzer will stay on at an idle but it goes off if engine rpms are 1700. I have changed the filter and cleaned inlet screen. I am going to check pressure at the sending unit tomorrow does any one know what the pressure should be at?

check pressure first, probably pressure sensor

I ran into this once. It turned out to be the bolt that holds the inlet tube inside the transmission came out, and let the tube come apart. This causes and air leak into the system, because the only thing that seals them is an O ring. The reason it works at higher RPM is because there is more flow from the pump to compensate for the air. If you have questions you can call me at 563 382 4530 M-F CST 8-5.

Finally got around to putting a gauge on it. And at an idle it does fall to 0 when the hydraulics are activated but with throttle wide open it stays around 30 psi. Can I get to the charge pump with out taking the cab completely off?
