2010 Malibu error codes po700,po716,po717


DTC P0700: Transmission Control Module (TCM) Requested MIL Illumination

Which one of these transmissions does your Malibu have ?
Automatic Transmission - 4T45-E
Automatic Transmission - 6T40/6T45
Automatic Transmission - 6T70/6T75

Do you know how to find out look at the VIN # ?
DTC P0716: Input Speed Sensor Performance
DTC P0717: Input Speed Sensor Circuit Low Voltage
The automatic transmission input speed sensor (ISS) is a permanent magnet with a coil of wire wound around. The ISS mounts in the case cover facing the reluctor wheel of the input shaft. As the reluctor wheel is driven by the turbine shaft, an AC signal is induced in the input speed sensor. Higher vehicle speeds induce a higher frequency and voltage at the sensor. There is a fixed air gap between the sensor and the teeth on the sensor reluctor wheel. The ISS input is used by the transmission control module (TCM) in order to control line pressure, torque converter clutch (TCC) apply and release, and transmission shift patterns. This sensor is also used to calculate the appropriate gear ratios and TCC slippage. This diagnostic indicates stuck, erratic, or intermittent conditions in the system.
Diagnostic Aids
• Road test the vehicle while monitoring the Transmission ISS parameter on the scan tool. The Transmission ISS parameter should vary with engine speed changes and not abruptly drop out.
• Inspect for an open or shorted AT ISS wire.
• Inspect for a disconnected AT ISS connector.
• Inspect for a faulty AT ISS.

My 1997 mitsubishi legnum st v6 triptronic auto trans failed local garage has informed me the pump inside has failed and cant be repaired are they worth rebuilding


dont believe it,those trannys have issues,not the pump though,bing search triptronic trans and see the same problems,

tRANSMISSION CONTROL UNIT. Some of these that have these issues most of them are the Input Speed Sensor , or the reading. If its reading an abnormal rotation speed it will start the transmission at a higher gear , being it cannot properly evaluate wut speed the input shaft is turning at versus the output shaft , it cant properly modulate teh shifting pressure and this will cause the initial "clonk" when getting it into a lower selected gear.

This issue can be caused by the TCM and also the Input shaft sensor also.

Speed sensor


Speedometer sensor measures axle(driveshaft) speed for your speedometer gauge.
Input speed sensor measures the speed of the input shaft of the transmission.
The output speed sensor measures the output shaft, the ECM compares these two signals to determine the amount of clutch slippage and adjusts parameters accordingly for optimal operation.

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please

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

Input speed sensor


The input shaft speed sensor is located on the side of the transmission by where the engine "inputs" power to the transmission (via torque converter), thus rotating the input shaft.
The output speed sensor is located by where the axles attach to the transmission, and measures the speed that the transmission "outputs" to the axles (which make the wheels turn) and that data is also used for your speedometer reading.
