Is your vehicle experiencing jerking in the auto gearbox? Let’s discuss some possible causes and their solutions.

1. Dirty Gear Oil

Did you know that insufficient or dirty gear oil, and incorrect oil, can lead to problematic gear shifts? If you are facing such an issue, check and top up or replace the gear oil according to the vehicle manual. Additionally, worn pressure plates or damaged parts can cause this issue. A professional inspection is needed to diagnose and replace the worn parts.

2. Transmission Control Module (TCM) Issues

Did you know that a malfunctioning Transmission Control Module (TCM) can lead to jerking in the auto gearbox? Diagnose the TCM and reprogram or replace it if necessary. This can help you avoid jerking issues. Problems with sensors like the throttle position sensor or vehicle speed sensor can also affect the auto gearbox. Identify and replace faulty sensors.

3. Hydraulic Issues

Did you know that hydraulic issues can cause jerking in your vehicle’s auto gearbox? Inadequate hydraulic pressure due to a transmission valve body problem can cause jerking. Inspect and repair the valve body if necessary.

4. Aggressive Driving Habits

Did you know that aggressive driving habits can lead to jerking in the auto gearbox? Hard acceleration or braking can cause this issue. Following smooth driving practices can help prevent jerking in the auto gearbox.

Use an OBD-II scanner to diagnose trouble codes (DTCs) related to the jerking issue. If DIY solutions don’t resolve the problem, consult a professional mechanic for a full diagnosis. Identifying the problem early can prevent further damage and costly repairs.
