Try the vehicles vss (speed sensor) it will definitly cause the speedo to stop working and the hard shifts. When your vss goes out it automatically goes into LIMPIN mode to protect the transmission from from damage. the vss is located next to the oil filter and looks similar to small distributor.Its about 130-150$ but it should solve the problem. I have been doin transmissions for about 8 years i hopes this helps you.

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 ?

I was driving approx.60mph,when my speedometer stop working and the trans.seem to shift into second gear,I believe it to be a speed sensor problem. I do not know the location of it though.


You probably have a blown fuse that conrols the speedometer and shift point of the transmission; Check the fuses inside the car under the dash on the driver side. The speedometer tells the transmission when to shift.

My speedometer stoped working, and my tranny shifts hard into second. and once it shifts into second the overdrive button comes on, and flashes.


WELL DIDNT TELL ME THE YEAR OF TRUCK CHECK TRANSMISION FUSE FIRST.IF ALL IS GOOD LOW TRANSMISSION FLUID OR STOPPED UP TRANSMISSION FILTER AND OLD FLUID CAUSE SHIFTING PROBLEMS.FAULTY VSS SENSOR WILL CAUSES TRANSMISSION SHIFT PROBLEMS.IF YOU HAVE NEWER MODEL TRUCK FAULTY TCM OR TRANSMISSION CONTROL MODULE FAULTY.

99 Mercury sable speedo/tranny


VSS (vehicle speed sensor) Tells the PCM (computer) the speed of the vehicle so the PCM can make the proper information to the TCM (transmission control module) to shift.
YOU are goin gto need a scan tool NOt a code reader to monitor the VSS to see what it is putting out for speed when the car is moving But I believe you need a VSS but do not not Go out and buy one until you have had it tested , and can positively confrim it is bad first. Please rate this a fixya if you find this advice helpful, Thanks Randy
