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!

WHEN DRIVING AND THE TRANS NEEDS TO SHIFT ON MY 2005 VW JETTA 2.5-5 NEW STYLE THE RPM'S REV UP BRIEFLY THEN THE TRANS WILL SHIFT THE SHIFTING IS SMOOTH BUT THE HIGH RPMS WORRY ME.


when vw started to use the computer controlled gearbox system a criticism was the shift was very harsh,to counter this they made it rev slightly before changing.so that you know the system, try this out....without touching the gas.....put it in d and let the car accelerate to its max speed,stop,then use 1/3rd of gas (keep your foot still)and let it do the same...stop,then,if safe,put your foot to the floor,hard, notice when the car changes gear(revs/speed)then if you drive,only using the first1/3rd of the gas,the cars change pattern will alter to suit.......wierd it is.....

I have had my tiburon less than a year but about a month ago the transmission started to act weird. At first it began shifting between i think third and fourth gear which made the rpms go higher than they...


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.

Your transmission is "downshifting" which is a normal function...However if it's happening early, the throttle cable may be out of adjustment. This does not happen in 3rd gear because that's how the system is designed. Downshifting is a 4 (od) to 3rd gear shift...if already in 3rd, this won't happen. As long as trans shifts normally on flat ground with no slipping or delayed shifts, just service it regularly and it should be fine.
