ok so there was this couch... It was abandoned and mocking me for a month. So I ran it over... Several times. It turns out that the couch got its revenge on my last pass. I tore out the wiring to my Output Shaft Speed Sensor and broke off the sensor itself. Seems easy right? Nope.
I went to a junk yard and acquired the replacement wiring and replaced the Speed Sensor. Still in "limp mode". I then replaced the Transmission Governor Pressure Sensor and the Transmission Pressure Sensor Transducer while I had the pan cracked (with a trans fluid and filter change of course).
Here's the extra info: CEL shows P1762 and P1763, I have checked all the fuses, and disconnected the battery after the parts install. By "limp mode" I mean that I am either locked into first gear, or that I have all the gears BUT first gear.
ok I just re-checked the wiring, and it appears to be connected to everything that it should be connected to, and I disconnected the battery again for several hours with no change... "limp mode" ensues. I'm out of any intelligent ideas. The transmission shop vultures are circling and starting to drool. HELP!
Several days after I replaced the Governor Pressure Solenoid and the Pressure Sensor Transducer, my trans began to shift properly again. My best guess is that it took some time/miles to work the trans fluid into the new parts?? Can anyone shed some light on if this is a possible/likely reason, or if I still have a problem that may return?
