SHIFT SOLENOID CODE

Luckily, most of these parts can either be fixed or replaced This is also the case for the shift solenoid. Signs and symptoms of a bad shift solenoid If it didn’t do this, then you would have functional problems with your car and the shift solenoid, which is what we are going to tell you about next. The computer in the car is constantly controlling the transmission’s fluid levels. The computer part of the car does help with this: the shift solenoid does its job by the computer part of the car. The purpose of the shift solenoid is continuously open, close, then reopen valves in the transmission, which helps regulate hydraulic fluid that would need to be checked in order for it to not continuously flow throughout the transmission, which would obviously cause problems if it did. Simply put, the transmission system is linked with the engine, with the engine sending constant energy to the transmission system, which then goes to the wheels of the car. The transmission system in basic terms takes power made by the engine and is sent to the wheels of the car, which then will help move the wheels of the car. It is a part of the transmission system and is actually controlled by the computer in the car.

YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. These leaks should be addressed and the fluid level filled to specification before any repairs are made to the shift solenoids or valve body. Low transmission fluid level is typically due to leaks. When this happens replacing the shift solenoid is only a bandaid for a transmission that is failing.įluid level is very important for the valve body and all shift solenoids to operate properly. In some circumstances, P0750 can fail to operate properly due to the solenoid being clogged with metallic particles from the transmission.

Transmission fluid change or correcting fluid levelĪdditional comments for consideration regarding the P0750 code.In cases where the vehicle will not shift out of gear, the car should not be driven, as this is a safety hazard that can also cause further transmission damage. If the transmission fluid is found to be excessively dirty and has metallic particles clogging the valve body or shift solenoid causing P0750, this may be due to mechanical wear inside the transmission. P0750 has the potential to be the first sign of a serious transmission issue. Some will have hot and cold lines on the dipstick or may not have a dipstick at all. Some vehicles may need to be checked with the vehicle running in neutral or in park. One common mistake is not paying attention to the manufacturer's way of checking the transmission fluid. Mistakes can easily be made if diagnostic steps are not done in correct order or if steps are skipped completely. If no conclusive faults are found, the transmission fluid may be drained and the transmission pan removed to inspect the shift solenoid A and the valve body itself.Ĭommon mistakes when diagnosing the P0750 code Once the fluid level is found to be within range, the scan tool will be used to monitor the shift solenoid A performance and values. Next, the transmission fluid will be checked. Once the vehicle is back at the shop, a visual inspection will be performed looking for any damage or possible transmission leaks. The mechanic will begin by using a scan tool to access the ECU and check for any stored codes and the freeze frame data associated with each code.Ĭodes will then be cleared and a test drive taken to verify the fault is present. How does a mechanic diagnose the P0750 code? A decrease in fuel economy may be noticed in addition to a vehicle that runs poorly or appears to misfire. The most common symptom is the vehicle may not shift from 1st to 2nd gear or the shift will be very rough. In all cases the Check Engine Light will be displayed on the dashboard. Poor electrical connection for shift solenoid A.Dirty or contaminated transmission fluid.This fault will display a Check Engine Light on the dashboard and put the vehicle into a failsafe mode. The P0750 will be set when the Powertrain Control Module (PCM) detects a fault with shift solenoid “A.” The PCM controls the shift solenoid by commanding the solenoid when to engage and disengage. This code may be seen with other shift solenoid or transmission codes. P0750 indicates a malfunction for a transmission shift solenoid.
