SOURCE: 2001 dodge durango v8 5.9 trans won't shift unless i downshift

I have a 2000, there is a speed sensor located in top of the rear axel and I believe another on the tranny housing. Try the rear axel first.

SOURCE: 1993 olds achieva-gears won't shift-what sensors on transmission

Had this problem when I rebuilt my engine. Turns out, that I had plugged back in a sensor that was previously unplugged. There is a known manufacturer's defect on some Achievas where a sensor on the transmission was mounted upside-down. Symptoms caused by this are primarily the car staying in gear (and thus stalling) when stopped, and failing to downshift while slowing down. Just unplug this pesky sensor, located roughly underneath and to the battery side of the throttle body. Be careful, though, because I don't know if running long term in this configuration will lead to transmission damage (although my transmission doesn't show any signs of troubles now that the thing is disconnected.)

SOURCE: speedometer doesnt work and it wont shift

Check the speed sensor again and make sure that the wire harness is not damaged in any way. Go to a Auto Zone and have them rescan the DTC codes and see if the VVS has gone bad from time to time in the history. Check the wire harness to the ECM on the passenger side in the engine compartment by the overflow tank. Make sure there are no damages to the clips and wires. Other then that it could be a bad sensor that may have been installed. Good luck and hope this helps.

What does the input sensor on your transmisson of a Pontiac G5 se 2007 do


The speedometer not working wouldn't be caused by an input sensor . The VSS - vehicle speed sensor is a direct input to the PCM , the PCM shares is info over the GMLAN data bus.
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on GMLAN serial data message from the body control module (BCM). The BCM receives vehicle speed data from the powertrain control module (PCM)/engine control module (ECM) via the GMLAN serial data circuit. The speedometer will default to 0 km/h (0 mph) if:
?€¢
The PCM/ECM detects a malfunction in the vehicle speed sensor circuit.


?€¢
The BCM detects a loss of GMLAN communications with the PCM/ECM.


?€¢
The IPC detects a loss of GMLAN communications with the BCM.


The only way to diagnose these problems is with a factory scan tool , this will check inputs an outputs at the PCM an BCM to the instrument cluster . This avoids guessing an playing the parts game. Your best bet would be to take your vehicle to a qualified repair shop .
Same thing with trans not shifting out of first gear , could be a shift solenoid ! Does it shift manually , moving gear selector through the gears ?

The speedometer stop working


it could be a speed sensor problem causing this as the TCM doesn`t know what speed its at in order to shift gears.

Tranmission and instrument cluster


The speed sensor on your trans sends a signal to the electronics telling it when to shift, this will be where you fault is.

Speed odometer stops cruise doesnt werk when this happens and the trans also shifts up and down during this time


The most likely cause,besides the speedometer being bad is the vehicle speed sensor in the transmission.It is mounted on the outside of the transmission and is fairly easy to replace.

CANT FIND WHERE THE SPEED SENSOR IS NO MY 1995 OLDSMOBILE AURORA


hi , their is two different speed sensors on your vehicle one is the input speed sensor which is inside the transmission and the transmission will have to be removed to replace it the other one s the output speed sensor is located directly above the passenger side trans-axle shaft. your input sensor is the sensor which tells the transmission when to shift and the output speed sensor tells the speedometer what it should display and both those parts are fairly cheap they are around 15-25 dollars but just remember if your input speed sensor is bad it is gonna cost you a minimum of 1000 dollars to have a mechanic fix as the transmission needs to be removed hope this is what you needed

Could a broken speedometer cause the transmission to not shift properly?


Yes if the vehicle speed sensor is bad than the computer can what speed you are going .SO the shifting comes from the throttle position sensor instead and trans shifting will be erratic :)
