The car's computer is having trouble talking to the part that controls the gears.
The Transmission Control Module (TCM) is detecting interference or errors in its operation.
The P17B0 code indicates that the Transmission Control Module (TCM) has detected an internal error related to its interference counter reaching a level above the acceptable threshold. This suggests potential issues with the TCM's ability to process or transmit data correctly, possibly due to electrical interference or a fault within the module itself.
• Check Engine Light is on
• Transmission not shifting properly
• Vehicle may enter limp mode
• Faulty Transmission Control Module
• Electrical interference from other components
• Poor wiring or connection issues
