SOURCE: shifting gears

the speed sensor is for Overdrive only, it does not shift the gears it sends the signal to the transmission control module that in turn signals the overdrive shift solenoid to engage/shift into OD.

SOURCE: my 2000 taurus would stay in first gear it would

if your speedometer does not work i would change the output speed sensor that would be the two wire plug that bolts on to the top of the transmission, because that speed sensor get looked at from your transmission ecm and you engine ecm. Right now the computer doesnt know how fast your going so your car has moved into SAFE MODE this mode will not let you out of first gear and if your try to go faster it will stall the car. Good luck

SOURCE: 2001 dodge stratus wont shift

Good Evening, I have a dumb question. have you cleared any current or history codes in the transmission? They will default with codes in the system. Also make note on what they are. If any and we can go from there, and yes tcm would be the next place to go but more info is best as far as codes and such.

I have a Suzuki Jimny automatic 2007. It has 3 buttons to select gear type. None of these are now working.


Start by looking at the fuse box... check all the fuses. Next possibility is a relay.

The Suzuki Jimny Transmission Control Module (TCM) is an electronic circuit component that controls gear shift, TCC lock-up and idle-up according to the signal from each sensor. It is a microcomputer consisting of an IC, transistor, diode, etc. It is installed behind glove box.

1. Ignition switch
2. Transmission range sensor
3. Input shaft speed sensor
4. Output shaft speed sensor (A/T VSS)
5. Shield wire
6. Vehicle speed sensor (VSS)
7. Transmission fluid temperature sensor
8. Shift solenoid-A (Shift solenoid No.1)
9. Shift solenoid-B (Shift solenoid No.2)
10. Shift solenoid-C (Shift solenoid No.3)
11. Shift solenoid-D (Shift solenoid No.4) 12. TCC solenoid (Lock-up solenoid)
13. "O/D" cut switch
14. "O/D OFF" lamp
15. Monitor connector No.2
16. DLC
17. To ECM
18. To A/C
19. To brake lamp switch
20. To main relay
21. Terminal arrangement of TCM coupler

2007 3.5 dodge Dakota rpm sensor where is it located to replace


Not sure what you mean by rpm sensor. The signal for the tachometer comes from the PCM and is based on signals from the crankshaft position sensor, located on the right rear of the engine where the transmission bolts to the engine, but if this is bad, there are a lot more problems than the tachometer not working. There are two speed sensors on automatic transmissions, an input speed sensor and an output speed sensor. Both are located on the left side of the transmission, the input speed sensor near the front (just behind the bell shaped portion) and the output speed sensor near the rear. In addition to those there are wheel speed sensors for the ABS, located in each wheel area covered by the ABS.

Whats a p0700.....


P0700 Fault Code Definition
  • Transmission Control System Malfunction
What does this mean?
The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels.
When the code P0700 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is seeing greater than a specified RPM difference between the rotational speed of the Input RPM Sensor and the Transmission Output RPM Sensor. This can occur during shifting or when driving at steady speeds in the same gear. It often implies that the transmission is slipping.
Symptoms
  • Check Engine Light will illuminate
  • Vehicle will not shift properly
  • Decrease in fuel economy
  • In unusual cases, there are no adverse conditions noticed by the driver
  • In some cases, there may be performance problems, such as dying when coming to a stop after driving on the freeway and/or misfire-like symptoms
Common Problems That Trigger the P0700 Code
  • Defective Shift Solenoids
  • Defective Engine Coolant Temperature Sensor
  • Defective Valve Body
  • Dirty transmission fluid that restricts the hydraulic passages
Common Misdiagnoses
  • Engine Misfire problem
  • Internal Transmission problem
  • Driveline problem

1999 jeep Cherokee classic. It will not go into 1st gear. It says it is the input speed sensor. Check gauge light comes on now. I replaced the alternator , input speed sensor and battery. Its over c


It says ? what says? the SCAN TOOL>?

non GRAND, (no engine stated, so fail there 1st)

my guess is you have a DTC and forgot to post that. why do that?

the DTC is covered in the FSM manual, and shows what is failing.

why not read the FSM and do what it says to do?



ill no attempt to read the FSM for you,. and that vague error.

why not log in to alldata.com and stop guessing. at parts.

there is no reason to gue$$



my guess at he DTC,

P0500"

or was it the P07xx series, all A/T errors.



P1xxx codes are factory code, got them? need all codes, not just 1 of many. and using a real scan tool not some POS autozoned junk (free)



p0500 is ASE jargon (best ) is VSS sensors.

vehicle speed sensor.



the transmission TCM monitors many inputs, and if they are bad

it can NOT shift, one such sensor is SPEED. MPH or VSS

the tail shaft all all 42RE transmission has a tail rpm sensor

when dead the cars speedometer goes dead, and the TCM

is at a lost to shift to 2nd gear, if speed is 0 all day.

a hopeless deal there.



if the battery voltage is not over 15v, its not overcharging, running.

99 is a nice jeep, id fix mine, ive had many.



the tranny has 2 speed sensors.

the front sensor does not do MPH, its just engine tranny input RPM

there are 3 RPM sensor

Engine, RPM called, CKP

tranny input sensor that tells the TCM true clutch slip at all time

and if the TCC works or not.

the tail shaft is the true speed sensor, vehicle speed, it\'s on tail shaft.



my guess, is the tail sensor is bad and you replaced the front sensor

P-0715 is a bad input sensor

P0720 and up are output sensor errors.

the 500 , is the 3rd sensor, the tail shaft sensor that runs the speedo

1st google hit.

http://www.jeepsunlimited.com/forums/showthread.php?548105-P0500-Vehicle-Speed-Sensor-Malfunction



next time post real DTCs

so we can jump on the exact part and the simple tests





the beauty of 3 sensors, is the transmission runs better

shifts better

and the OBD2 diagnostics are dead nuts, accurate.

it can see illegal gear slips (bad clutch packs) in any gear

and tell you. one of the best there.are

if you had new car, with 9speed, good luck keeping that card house going.. really.

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

Were is speed censour located


the output speed sensor is located on the transmission. while standing in front of the vehicle and looking down at the transmission you will see two rubber hoses. under those hoses you will see the input speed sensor. if you look to the right of that sensor, and you may have to look from underneath the vehicle you will see another sensor that is identical to the input speed sensor. That is the output speed sensor. The output speed sensor is the one that shows how fast you are moving on the speedometer.

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
