Where inhte car are the transmission sensors?

The transmission sensor or speed sensor is located in most vehicle located on the transmission case.These speed sensors are driven by a gear located on the output shaft. The speed sensor's driven gear can be either machined or fastened by a clip. The driven gear is made by plastic to make it softer than the drive gear. It's located on the end of the vehicle speed sensor.

Hi, to remove the sensor and gear assembly, remove the 10mm bolt attaching it to the transmission. Then, twist back and forth while lifting out of the transmission.
Once you remove the sensor, you'll have the sensor and gear out of the transmission. Check the plastic gear. If the teeth are damaged--usually, the center portion of the teeth is worn-- you'll need a new gear. To remove the gear from the sensor, simply remove the clip holding the gear onto the sensor...

sounds to me like water is leaking into something electrical. either that, or one of the transmission sensors located underneath the transmission is having water damage. to check the computer, it is located underneat the glove compartment. lift the rug up, and there are two computers, the one on the right is the tcu or transmission computer. check to see if there are any damaged cables, and cover them if there are. or you can remove the computer itself, open it, and check to see if there is any damage to the inside of the computer. if there is, go to the junkyard and pick one up, there around 50, compared to 200 new at the dealer or online. the other place you can check is the transmission itself. lift the car up from the passanger's side, (make sure to use proper precautions) and check the counter shaft speed sensor and your mainshaft speed sensor to see if the wires are exposed. they are located underneath the transmission

heres a link that shows the 4 trasmission sensors that have any control over the shifts. the picture shows the sensors if the transmission would be see through. the last thing and probably the first thing you should check because it is the easiest would be the two solenoids in front of the transmission. the link is pointing at both solenoids but only one of them is being named because the other one is being cut out of the picture. i hope this helps and goodluck. and if you need further help, let me know

well this engines are notorius to rougth idle, but my sugestion is to inspect your coolant temp sensor, check for corrotion in conector if any clean or replace conector, your engine has two temp sensor one is a single wire for your temp gage and other believe green conector with two wires this is for your computer, if no rust or corrotion found replace the sensor.
good luck

LEVEL CHECK -manual transmission The vehicle speed sensor (speedometer gear), which is located on the transaxle, serves as the manual transaxle's dipstick.

1. Park the car on a level surface, turn the engine OFF and apply the parking brake.
2. Locate the speedometer cable assembly where it enters the transaxle.
3. Unplug the electrical connection from the vehicle speed sensor (speedometer gear).
4. Disconnect the speedometer cable from the speed sensor.
5. Wipe the area around the speed sensor with a clean rag, then loosen the speed sensor retaining bolt.
6. Gently pry the speed sensor from the transaxle. Fig. 1: Location of the manual transaxle's fluid level marks — 1.8L engine
   Fig. 2: Location of the manual transaxle's fluid level marks — 1.9L and 2.0L engines
   
   
7. Check the condition of the speed sensor O-ring and replace it if it is damaged.
8. Check the fluid level on the speed sensor as illustrated.
9. If the level is low, place a funnel in the speed sensor hole.
10. Add the specified fluid to the transaxle until the FULL level is reached. Do not overfill the transaxle.
11. Install the speed sensor and tighten the retaining bolt to 69–104 inch lbs. (8–12 Nm).
12. Connect the speedometer cable.
13. Engage the speed sensor electrical connection. Fig. 3: If necessary, add transmission fluid through a funnel into the speed sensor opening
    

Check your wire harness to the transmission located on the drivers side under the battery, look for any damaged or disconnected wire harness and also inspect the wire leads to the harness at your TCM (transmission control module) located on the passenger side fender. Check the fuse to your TCM and don't forget to check the fuses under the dash on the drivers side, replace any fuse that has gone bad.
Good luck and hope this helps, 85% of the time it's going to be a electrical issue that causes your transmission not shift properly. The other causes for your transmission issues are: TPS sensor and the input speed sensor and out put speed sensor in your transmission.
Thank you for using Fixya and start with the simple and check the fuses and wire harness. Good luck

Do you have codes with that engine light?
Do you have a digital odometer?
Insert the Key into the Ignition and
Turn from OFF to ON (not Start) ON is just before Start.
Do this 3-times: OFF to ON (not start), OFF to ON (not start), and OFF to ON (not to start).
Leave the Key in the ON (not start) Position.
Look at the Digital Odometer.
With the Egine Light on there will be Codes in the Odometer Display.
Record these Codes and get these Codes back to me.
These codes should pinpoint the Problem.

What is the Transmission Fluid Level and Condition?
Remember to Check the Transmission Fluid with the Engine On and at Normal operating temperature. Check it with the vehicle in Park or in Neutral (WITH the Parking Brake engaged).
When was your Transmission Fluid and Filter Changed?
After 35,000 miles they should be changed. Do not get the Superflush, as this does not change out the filter. Use the correct, recommended Transmission Fluid, do not buy the cheap stuff.

The "brain" they are talking about is the Transmission Solenoid. It looks like a box, and is usually found on the front of the Transmission Because of it's location the electrical connections are prone to corrosion and oxidation (white stuff) on the electrical connectors, causing problems with shifting. You can remove the electrical connections from ALL the connectors on the vehicle; Check and Clean then and re-plug them back in, and check operations.
The Transmission also has Sensors. These are easily located on the Transmission. They send electronic information to the computers and are used during shifting. As stated earlier: remove the electrical connections for each sensor, and clean both sides of the connections.
One or more of these Sensors may be malfunctioning, causing the shifting problems. You may also easily remove these Sensors and clean the inside end of the sensor (they gather small metal particles on them), reinstall, replug and check operations.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

check the oil descending unit or ur oil pump might b clogged up with soot, just some advice hope it works

Hi.....
The CODE : P0510. Is .. Throttle Position switch mal funtion.

The Step to fix this problem.
1- Check the connection of the TPS. Throttle position sensor.
2- Check visual the condittion of the sensor. fro breack down.
3- Check the wires for damaged shield covers. corrotion on the pins connector.
4- Clear the Code with the scanner.
If the code RETURN. REPLACE the TPS sensor.

OK... I hope this help on your problem.

Thank you for use fixya....

Check VSS Vehicule Speed Sensor wire may be corroted, bad connection or faulty; if 2wd the adaptor is located on the extension housing of the transmission (left side)
if 4wd look on transfer case extension (left side)

Good luck
