Frequently Asked Questions

What does P0953 indicate?

P0953 indicates a problem with the reverse to neutral shift performance (at). This is a transmission control system code that requires professional diagnosis.

Do I need a transmission rebuild?

Codes indicating no gear engagement or poor shift performance often indicate internal wear that may require a rebuild or replacement. However, always verify electrical and fluid conditions first.
