Having problems with your Pontiac Sunfire ?

Sensor map If the sensor is not working properly will this cause the auto transmission not to shift properly?

Posted / edited by AnonymousUser on : 15-01-2018

Answers :

I doubt it.
The map sensor reads manifold vac and sends a signal to the computer. If the signal is out of range, the check engine light should come on. If the check engine light is on, that might affect trans performance.

My car started pouring out transmission fluid while driving on the freeway earlier today. I had my transmission inspected yesterday at AAMCO because my car was shifting late. They determined that the speed sensor was malfunctioning and replaced it. I assume they messed up on something since it started dumping out fluid so quickly after their work. Is there something involved in replacing a speed sensor that could cause a leak? I just want to be prepared for when I talk to AAMCO again on mon

I have a 1998 Jeep Grand Cherokee Laredo 4x4. The check engine light came on a little bit ago, and ever since then it's had problems shifting out of first gear. I'll be running 4000 rpm for miles before it shifts. The transmission fluid is full, and it doesn't ever overheat even though it's running so high. I've taken it to several shops, had diagnostics ran, and every shop says something different. We replaced the speed sensor and that helped a little but it still doesn't work properly.

It is most likley the throttle position sensor"mine wouldn't shift into 5th gear because of it" if it bad or worn out it not sending the correct signal to the computer telling the transmission to shift out. before you get lied to by the auto parts st ... 1998 Jeep Grand Cherokee

My 2000 Hyundai Elantra is stalling intermintantly as I slow down at stop signs/lights, etc. I have noticed that the speedometer is not working properly.....i.e. when I'm moving at 30 mph the speedo is reading 10 mph ? But no engine lights are present.... I would think that this should cause a speed sensor/throttle sensor/fuel type sensor to activate a light ? Is there a possibility that the computer is bad ? Is the speed sensor external ? and is there a seperate computer for the transmission ?

According to the Hyundai service website, "If there is an open or short circuit in the vehicle speed sensor signal \012circuit, the engine may stall when the vehicle is decelerated to a stop." This sounds like what you're describing, so you should ch ... 2000 Hyundai Elantra

I have a 1992 chevy 4x4 truck with a 4l80e transmission. Just got it rebuilt and put a shift kit in it. It will work when i first take off then it will drop overdrive after a couple miles. It comes up with a code 68 overdrive error. I unpluged the input sensor on the trans and I picked up overdrive again. Does that mean that sensor is bad or what could cause that?

When the car is started and then shifted into drive you can feel it engage. It will move forward and even seems to shift properly until the transmission warms up. Once it warms up and you stop it will not move forward after it is put into drive. If you do get it to move forward it will not shift out of first gear no matter how fast you go or how slow. I changed the transmission fluid and filter and it seemed to work fine and shift properly for probably less then 20 miles then it reverted back to

Transmission trouble When my '99 Crown Vic shifts from first to second gear it does not shift smoothly. There is a noticeable bump. I've also noticed that sometimes the automatic door locks don't work when I try to activate them with the switch on the armrest although they work fine when activated by the remote keyfob.
