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.


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.
