Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Ensure the vehicle is cool before opening any fluid reservoirs.

Symptoms

•Slipping sensation during acceleration
•Unusual engine revving without corresponding vehicle speed increase
•Delayed or harsh shifting between gears
•Possible warning lights on the dashboard (e.g., transmission warning light)

Check the transmission fluid level and condition; ensure it is at the correct level and not burnt.
3
Inspect the drive belts and chains for wear or damage.
4
Conduct a visual inspection of the transmission for any signs of leaks or damage.
5
Test drive the vehicle to replicate the slipping sensation and note any specific conditions (speed, engine load).
6
Inspect the throttle position sensor and mass airflow sensor for proper operation.
