This summary uses the existing diagnostic information shown in full below.
The car's computer that helps control the gears isn't getting the power it needs to work properly.
The Transmission Control Module (TCM) requires a stable power supply to function correctly. This code indicates an issue with the power input signal to the TCM.
The P0880 code is triggered when the Powertrain Control Module (PCM) or TCM detects a problem with the power input signal to the TCM. This could be due to a faulty connection, wiring issue, or a problem with the TCM itself. The TCM relies on a constant voltage supply to manage transmission operations effectively.

This code has been commonly reported in vehicles with high mileage or those exposed to harsh environmental conditions.
High – This issue can affect vehicle drivability and should be addressed promptly.
Driving with a malfunctioning transmission can be dangerous. Ensure repairs are conducted by a qualified technician.
• Vehicle in park or neutral
• Engine running
The TCM is usually located near the transmission or within the engine bay.
Q: Can I drive with a P0880 code?
A: It's not recommended as it can lead to transmission issues and potential safety risks.
Q: How do I reset the P0880 code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
