What is the code for shift timing solenoid a malfunction?
What is the code for shift timing solenoid a malfunction?
The code P0785 Shift Timing Solenoid A Malfunction is set there is a general malfunction present within the solenoid or its circuit. Note: If you have a GM vehicle (GMC/Chevrolet/etc.) with the 4L60-E transmission, the code description for this is actually Transmission 3-2 Shift Solenoid. What is the severity of this DTC?
Can a faulty solenoid cause a transmission to stop?
A faulty shift solenoid can cause the transmission to downshift uncontrollably (in other words at random times) or not downshift at all, even when coming to a complete stop. Erratic Shifts: A defective shift solenoid can also cause the transmission to shift erratically.
How to test shift solenoids on GM 4.3L?
In this article, I’ll show you how to test the transmission shift solenoids (specifically 1-2 solenoid and 2-3 solenoid) on your GM 4.3L, 5.0L, 5.7L pick up, van, SUV. You’ll be surprised just how easy it is to diagnose these shift solenoids when they have failed.
Where can I get a transmission shift solenoid replaced?
Once it is determined that you have a failed transmission shift solenoid the only repair is to replace the faulty part. Replacing a transmission shift solenoid can be done by most any auto repair shop, automobile dealership service center or you can do-it-yourself “DIY”.
The code P0785 Shift Timing Solenoid A Malfunction is set there is a general malfunction present within the solenoid or its circuit. Note: If you have a GM vehicle (GMC/Chevrolet/etc.) with the 4L60-E transmission, the code description for this is actually Transmission 3-2 Shift Solenoid. What is the severity of this DTC?
Why is my transmission solenoid not working properly?
If the transmission control unit is not able to open, the shift solenoid with help the power or ground, and it will store a trouble code in the transmission control unit on the affected shift solenoid. It’s also possible that the shift solenoid has an internal problem or is stuck so the transmission control unit can’t open it properly.
Where is the shift solenoid on an automatic transmission?
When it’s time to shift, the transmission control unit sends out power or ground to the required shift solenoid, and it causes the solenoid to open and let the transmission oil flow into the valve body, which then shifts to the next gear. The Transmission shift solenoids are located inside the valve body of your automatic transmission.
When to replace shift solenoids in GM 4L60-E?
TIP 4: If your transmission is slipping, replacing the shift solenoids, even if they’re fried will not solve the slipping issue. The 4L60-E transmissions uses several solenoids and sensors to control/activate its 4 gears.
What is the shifting solenoid on a Chevy S10?
The shifting solenoid on a Chevrolet S-10 pick-up is designed to regulate when the transmission shifts. This solenoid is part of the electronic transmission control system, and is controlled by the powertrain control module, or PCM. The PCM actuates the shifting solenoid when it determines that an upshift or downshift is required.
Is the 4L60-E transmission shift solenoid the same part number?
Let’s move on the next subheading and find out what are the most common symptoms when these two buggers fail. You can buy the 4L60-E transmission shift solenoids online (which will save you some bucks). Both the A and B shift solenoids are the same part number.

When does the Mil illuminate the shift timing solenoid?
The ECM (Engine Control Module) illuminates the MIL (Malfunction Indicator Lamp) with P0785 and associated codes ( P0786, P0787, P0788, and P0789) when it monitors one or more issues within the shift timing solenoid or it’s circuit. The circuit includes the TCM which depending on the model could be in a volatile location.
