Question about 1994 Chevrolet C/K 3500

1 Answer

After 10 to 15 mins driving, trans down shifts to 3rd

Will stop, turn off motor, restart and the system resets for another 10-15 mins.

I have been told that the wiring harness from the trans to the sensor usually rubs out and the sensor loses its signal which tells the trans to go to a safe gear.

Any recommendations on how a backyard mechanic can remedy this relatively cost effectively?

    Motorhome runs great but after a few minutes in all gears it just drops out of overdrive and will not shift until I stop the engine. I will then restart the engine and it seems like the sensor resets and it will drive well for another 15 mins.

    Since you were told, probably by other RV-ers, about a wiring problem I would check that first by checking all wires from the trans for obvious damage.

    If this doesn't work you should consider asking FixYa again but for the Guaranteed Answer. It really is amazing!

If tranny fluid is clear and at normal level, then the issue is with the transmission - it is getting ready to go sayonara.

Better get that fix before you get stranded.

the trans computer has seen a problem possible a bad sensor, or an internal problem, and puts it into a safe mode, or limp home mode , it wont shift , it will stay in 3rd gear, this way this reduces the possibility of further damage trans damage, when you turn the ignition off and back on it resets the tcm, my advice is to take it to your local dealer, they can diag your trans as they know the product, i dont advise pep boys, or discount auto parts.
