This summary uses the existing diagnostic information shown in full below.
The car's computer found a problem with the part that helps control the gears. Because of this, the car is in a special mode that makes it drive slower to keep it safe.
The Transmission Control Module (TCM) has detected an error in its internal monitoring system, which triggers a fail-safe mode known as Limp Home Mode.
The P1932 code indicates that the TCM has identified a Level 2 error in its internal monitoring processes. This error prompts the vehicle to enter Limp Home Mode 3, which is a protective measure to prevent further damage to the transmission by restricting performance.
• Reduced vehicle speed
• Transmission stuck in a single gear
• Check Engine Light illuminated
