Good evening, the vehicle's Transmission is not responding or moving when place in drive position, I scanned the vehicle the only code found on its memory is P0776. I removed the sump to access the solenoid, I applied voltage to them, all of them were clicking, then I erased the code from its memory after the test drive it works fine, after parking the vehicle for some time the code appeared again with the same symptoms. What could be done?

Hi,

The code is specific to the pressure control solenoid B. Did you actually replace it or just check the ones in the vehicle? As far as applying voltage to them, that isn't always a good way to check. How much voltage was applied?

If you did replace the solenoid, take a look through the attachments. They provide the diagnostics specific to this code and vehicle. Let me know if you are comfortable performing the tests.

Let me know.

Joe

Hi,

The solenoid valve (SL 2) is mounted on the valve body. If you look at the attached pic below, I highlighted it for you.

Let me know if this helps.

Take care,

Joe

Hi,

Glad to hear that. Was it the solenoid valve (SL2)?
