When I tow something heavy or my one kid takes the 97 to get bulk mulch and dirt, the 97 will set a P0503 code. Only does it loaded. She overloads it.
I would expect a slipping code but possibly there are none for that trans.
Checked the wiring and that looked fine. Doesn't do it any other time.
Only happens very rarely and there is no noticeable drivability issue.
Look at the sensor reading in Forscan and it seems perfect whenever it is being watched.
Is there anything other than a speed sensor or gear that would cause that code to set?
Trans is soon up for it's 50K mile fluid / filter change so I'll look at the speed sensor gear then.
Trans has 250K miles on latest rebuild, maybe it's time for another.
Aslo, Anyone have a good aftermarket remote start / alarm they would recommend that is wired in, not OBD plug in?
Check this feller in the rear diff first... I'd pull it and clean it.
