OBD-II Generic Error Code P0735: How to Fix It

Q: Can I drive with error code P0735?

It's not recommended. Driving with a gear ratio error can cause further damage to the transmission, leading to costlier repairs. Have the issue diagnosed as soon as possible.

Q: What does 'gear 5 incorrect ratio' mean?

It means the transmission's computer detected that the actual gear ratio when in 5th gear doesn't match the expected ratio. This often points to slipping, worn clutches, or a faulty solenoid.

The generic meaning is the same across OBD-II compliant vehicles, but specific troubleshooting steps and parts locations vary by make and model. Always refer to your vehicle's service manual.
