Where is the transmission shift solenoid located?
The transmission solenoids are usually located within the valve body, the transmission control unit, or the transmission control module. The transmission control unit is a device that controls the automatic transmission, and can use sensors to calculate the inner workings of each electrical part in your vehicle.
How do you know if your shift solenoids are bad?
Signs of a failing shift solenoid
- The check engine light comes on: The TCM continuously monitors shift solenoid operation.
- Erratic shifting or shift slippage: The shift solenoids regulate the flow of hydraulic fluid for shifting.
How do I free a stuck solenoid?
Wear and tear to the wire or slug can also cause the solenoid to become stuck. A gentle tap on the casing is enough to dislodge the metal slug so that the solenoid can work properly.
What causes a transmission code of p0758 to be issued?
Causes for this P0758 transmission code may include: Insufficient fluid level. Dirty or contaminated fluid. Dirty or clogged transmission filter. Defective transmission valve body. Restricted hydraulic passages.
What is an OBD code for shift solenoids?
In this case, the P0758 OBD-II trouble code is associated with a an electrical malfunction with the the transmission Shift Solenoid “B” Circuit. Example of shift solenoids:
What does shift solenoid valve on service engine soon warning light mean?
Engine Light ON (or Service Engine Soon Warning Light) Shift solenoid valve ‘B’ is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module ( ECM) (throttle opening). Gears will then be shifted to the optimum position.
What are the trouble codes for the B solenoid?
The trouble codes related to this, the “B” solenoid, are codes P0755, P0756, P0757, P0758 and P0759 based on the specific malfunction that alerts the PCM to set the code and illuminate the Check Engine Light. These codes will also be associated to the A, B or C solenoid circuit.
