The electronic sensor inside the transmission needs to be changed
Are you putting your foot on the brake ?
my 2001 ford windstar wont shift out of first gear.
If a 2001 Chevy Impala will not start after replacing a thermostat, perhaps it is possible that a sensor was bumped unknowingly. Check all of the sensors that might have been touched during the changing of the thermostat to see that they are all still plugged in.
Blown fuse, glass off the track or the cable that runs from the sunroof motor to the glass has busted.
Your transmission bands are bad, you need to replace them to make it work properly again.
You need to change the input and output sensors on the tranny
Check VSS or wiring to it could cause fault .does speedometer work?
Just turn the key to the first position, ( not on ) and then you will be able to shift to neutral and start the car from there. Have the fuses checked and check the shifter sensor on the brake pedal.
You proble need a new Trany I would check you fluids ! Check all lines and plugs for the Trany.
replace the shift cable
The most common reason for a transmission not to shift properly is low transmission fluid. Make sure the transmission fluid is up to the full mark.
becaus the 2004 Chevy impala does not have automatic lights and they have to be turned off manually
