Code P0776 Pontiac Description

The clutch pressure control (PC) solenoid 2 is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The clutch PC solenoid 2 flows fluid to the 3-5-R clutch when commanded OFF and exhausts fluid when commanded ON. The clutch PC solenoid 2 regulates the transmission fluid pressure to the 3-5-R clutch. The Transmission Control Module (TCM) calculates gear ratio based on data from the automatic transmission input speed sensor (ISS) and the output speed sensor (OSS). The TCM compares the known transmission gear ratio to a calculated gear ratio for each commanded gear.

Code Tech Notes

When a transmission solenoid is malfunctioned, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is dirty, it's recommended to change the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure and that the transmission will need to be rebuilt or replaced.

Frequently Asked Questions about P0776 Pontiac Code

What does OBDII code P0776 mean on a Pontiac?

P0776 indicates that the Powertrain Control Module (PCM) has detected an issue with the clutch pressure control solenoid 2, specifically that it is stuck in the "off" position.

What are the common symptoms of code P0776?

Symptoms may include harsh or delayed shifting, transmission slippage, poor fuel economy, the transmission going into limp mode, and the illumination of the check engine light.

What causes code P0776 to appear?

Common causes include a faulty clutch pressure control solenoid, low or dirty transmission fluid, a clogged transmission filter, internal transmission issues, or a problem with the wiring or connectors.

Can I drive my Pontiac with code P0776?

Driving with code P0776 is not recommended, as it can cause further damage to the transmission and compromise vehicle safety due to erratic shifting or slipping.

How do you diagnose the P0776 code?

Diagnosis involves checking the transmission fluid level and condition, inspecting wiring and connectors to the solenoid, conducting a solenoid resistance test, and possibly performing a hydraulic pressure test.

How much does it cost to fix code P0776 on a Pontiac?

Repair costs vary depending on the cause, ranging from $100 to $400 for solenoid replacement to over $1,000 if a transmission rebuild is required.

Can low transmission fluid trigger P0776?

Yes, low or contaminated transmission fluid can cause the solenoid to malfunction, leading to code P0776.

What is a clutch pressure control solenoid?

A clutch pressure control solenoid is an electronic component that regulates hydraulic pressure in the transmission to ensure smooth shifting between gears.

How do you fix a P0776 code?

Common fixes include replacing the faulty solenoid, changing or flushing the transmission fluid, repairing damaged wiring, or addressing internal transmission issues.

Will clearing the code fix the problem?

Clearing the code may temporarily turn off the check engine light, but the underlying issue must be addressed to prevent the code from returning.
