P2783 Fault Code

Torque Converter Temperature Too High

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2783 fault code indicates that the torque converter temperature has exceeded the acceptable threshold. This situation can arise from several factors including poor transmission fluid circulation, excessive load on the engine, or coolant problems within the transmission system.

What are the symptoms of the P2783 code?

Drivers may experience a range of symptoms when the torque converter temperature is too high, including:

• Slipping of the transmission
• Delayed or harsh shifting
• Overheating warning lights on the dashboard
• Burning smell from the transmission fluid
• Decreased engine performance or loss of power during acceleration.

What causes the P2783 code?

Several underlying issues can lead to overheating of the torque converter, such as:

• Insufficient or degraded transmission fluid
• Clogged transmission cooler or lines
• Excessive towing or heavy loads
• Malfunctioning torque converter lockup solenoid
• Transmission overheating due to external factors (e.g., high ambient temperatures or poor air circulation).

How to fix P2783?

To resolve the P2783 fault code, the following steps are recommended:

• Inspect and replace transmission fluid, ensuring it is clean and at the correct level.
• Check for clogs in the transmission cooler and lines, cleaning or replacing components as necessary.
• Assess the load being placed on the vehicle; reduce heavy towing or excessive payloads if applicable.
• Test and replace the torque converter lockup solenoid if found to be malfunctioning.
• Monitor transmission temperature and ensure that adequate cooling is being provided.
