The P0772 code is a generic powertrain code that indicates a problem with the shift solenoid D electrical circuit.
This code is most commonly found in automatic transmissions, and it can cause a variety of symptoms ranging from a harsh shift to a complete failure to shift at all.
In this article, we’ll take a closer look at the causes, symptoms, and potential solutions for the P0772 code. We’ll also discuss some common questions that people have about this code, so you can be better prepared to diagnose and fix this problem if it occurs in your vehicle.
Causes of the P0772 Code
The shift solenoid D is responsible for controlling the flow of transmission fluid through the transmission. When there is a problem with the electrical circuit that controls this solenoid, it can cause the transmission to shift improperly or not at all.
Some of the most common causes of the P0772 code include:
- Faulty shift solenoid D
- Wiring issues in the shift solenoid D circuit
- Malfunctioning transmission control module (TCM)
- Low transmission fluid levels
- Dirty or contaminated transmission fluid
- Internal transmission damage
Symptoms of the P0772 Code
When the P0772 code is present, you may experience a variety of symptoms depending on the severity of the problem. Some of the most common symptoms include:
- Harsh or delayed shifting
- Failure to shift into the proper gear
- Transmission slipping
- Reduced fuel efficiency
- Check engine light or other warning lights on the dashboard
If you notice any of these symptoms in your vehicle, it’s important to have your vehicle inspected by a qualified mechanic as soon as possible. Ignoring the problem can lead to more serious issues down the road.
Solutions for the P0772 Code
The best way to fix the P0772 code will depend on the specific cause of the problem. In some cases, a simple fix like replacing a faulty solenoid or repairing a damaged wire may be all that’s needed. In other cases, more extensive repairs may be required.
Some potential solutions for the P0772 code include:
- Replacing the shift solenoid D
- Repairing damaged wiring in the shift solenoid D circuit
- Replacing the transmission control module (TCM)
- Flushing and replacing the transmission fluid
- Rebuilding or replacing the transmission
If you’re not comfortable performing these repairs on your own, it’s best to take your vehicle to a qualified mechanic who can diagnose and fix the problem for you.
FAQs
Q: Can the P0772 code cause my transmission to fail completely?
A: In some cases, the P0772 code can cause the transmission to fail completely. If the solenoid is completely failed or the wiring is damaged beyond repair, it may be necessary to replace the transmission entirely.
Q: Can I still drive my car with the P0772 code?
A: You may be able to drive your car with the P0772 code, but it’s not recommended. Continuing to drive with a faulty transmission can lead to much more serious problems down the road.
Q: How much does it cost to repair the P0772 code?
A: The cost of repairing the P0772 code will depend on the specific cause of the problem and the extent of the damage. Simple repairs like replacing a solenoid or repairing a wire may cost just a few hundred dollars, while more extensive repairs like replacing the transmission can cost several thousand dollars.
Q: Can I fix the P0772 code on my own?
A: If you’re comfortable working with cars and have the necessary tools and knowledge, you may be able to fix the P0772 code on your own. However, if you’re not experienced with transmission repairs, it’s best to take your vehicle to a qualified mechanic.
Q: Is the P0772 code covered by my vehicle’s warranty?
A: Whether or not the P0772 code is covered by your vehicle’s warranty will depend on the specific terms of your warranty. If you’re not sure, it’s best to check with your dealer or the manufacturer to see if the repair is covered.
