NO, just replace the Vehicle Speed Sensor, it is on the transmission.

Likely you have a shift control module malfunction. Module is probably on the right side fender in the engine compartment. Check to see if you have one (some do and some dont... go figure...I've got a 91 & 95... I have about five different diagrams and NONE apply to my vehicles)

had same problem i would check the Idel Air Valve and also check all of your vaccum hose lines makeing sure there are no cracks or splits in rubber connectors if there is repair immediatelt because over time they start to dammage the internal parts fo the engine and if youve replace tps mass air etc. sounds like a vaccum hose problem

SOURCE: transmission won't shift

what kind of car is this? how old is it,most trannys go because NOBODY seems to change the fluid .I would change it every 50k,after ten years of no new fluid . You could try changing it and add a bottle of Lucas trans slip fluid with it, I have used it with at least 4 differant vehecles with success. But check you trans kick down cable first ,if it broke the car will not shift,Located right with throttle cable,one on top and the other right under it .

Can a bad thermostat make the transmission not shift in the 2008 v8 impalla


What do you mean by bad ? Thermostats can be stuck open or closed . Stuck closed , the engine will over heat . Stuck open the engine will not get up to operating temp . , your year vehicle , would cause a code to set . Wouldn't cause a transmission shift problem . Have the vehicle checked for DTC'S - diagnostic trouble codes . Now a faulty ECT - engine coolant temp. sensor could cause shifting .

Transmission problems


I suspect that the code should be p 0733
that is gear ratio 3 incorrect
some problems that trigger the code are
defective 3rd gear shift solenoid
defective 3rd gear related gear set or clutch pack
defective engine coolant temperature sensor unit
defective valve body
dirty transmission fluid that restricts the hydraulic passages
not knowing the repair history , if the torque converter was not replaced in the overhaul then there could be rubbish in it that is now in the box
the coolant temp sensor also reads excessive heat generated by the transmission oil cooler or the connection could be excessive oil temp reading
first thing to check is the wiring and harness connections as a connection not properly fitted may be the problem
it would help if you gave a history of the problem in the 14 miles --not shifting , slipping etc

Loss of power, studdering at high rpms when at temp.


Sound's like it break down due to no oil or water circulate
the engine. Or wrong spark plug gap. So it increase too much heat.

-Try this:
1. Flush the engine. Flush the coolant.
2. Check spark plug gap (Adjust to correct gap)
3. Check oil pressure. If it's low then new oil pump is need.

Good Luck

I unplugged the speed sensor and the car started shifting weird,


You likely have a defective shift solenoid inside the transmission. Have the dealer check the operation with a scanner.

I have a 1992 dodge diesel 3/4 ton pick up. I have owned it since new. It has been an awesome truck with very few problems. When the truck was about 5 years old I had to replace the TPS. It was continually...


you are correct as a single blade connection is mostly the temp gauge sender as the gauge grounds out through the variable resistance in the sender unit
most coolant temp sensor units have 4 wires in a square shaped plug and are generally in the same vicinity
I am at loss as to any transmission problems coming from a coolant sensor problem as the purpose of that unit is to report the engine coolant temp so that the ECM can adjust the air/fuel mix, turn on the radiator fans
There may be an transmission temp sensor to report to the ECM when the transmission overheats and that would put on the engine light
It appears that the recurring problem has again surfaced
but check harness connections for corroded pins , water ingress, and check the transmission control module for connections and operation
you may also check the vacuum actuator and hose for leaks and correct operation as that unit will attempt to change ratios as the throttle setting alters

did you change the coolant temp sensor and the air temp sensor. sounds more like the coolant sensor is not working right this could cause the computer to dump more fuel which would cause a rich burn and the shifting problems check the leakage on the trans.When was the last trans fluid change and filter?

2000 grand am transmission?


It isn't the coolant temp sensor. Did it start working again? Sounds like it lost power to the shift solenoids. Could be an ignition switch. Or just a blown fuse.

4l60e trans. will not shift out of 3rdgear...


Have it scanned. Have the person who scans it pay particular attention to the Transmission temp sensor. If the Transmission temp sensor tells the ecm the transmission is cold, it won't shift to 4th. Also if it thinks the transmission is too hot it won't allow a 3-4 shift.

Car seems to not shift into 3rd when cold


The transmission will NOT shift into the final gear (overdrive) when the coolant temperature is below 177 degrees F. The OD is coolant temperature controlled. In short, the colder it is outside, the colder the engine is, and takes longer to warm up to operating temperature. The coolant, when it reaches 177 degrees F, satisfies the temperature sensor, which allows the final shift. Assuming that you do not have a thermostat that is stuck slightly open, this is a normal occurance. Thanks for choosing FixYa for assistance.
