⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the electrical systems to prevent shock or shorts.
•Allow the engine to cool before working on the transmission fluid to avoid burns.

Symptoms

•Transmission hesitates or slips during acceleration
•Unusual noises while shifting (grinding or whining)
•Delay in engagement when shifting from park to drive or reverse
•Increased engine RPM without corresponding vehicle speed
•Dashboard warning lights (such as the transmission or check engine light) may illuminate
•Fluid leaks under the vehicle

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any transmission-related issues.
2
Check the transmission fluid level and condition; look for signs of contamination or burning smell.
3
Inspect for external leaks around the transmission pan and cooler lines.
4
Examine the transmission fluid for proper color (should be reddish and clear) and consistency.
5
Perform a road test to replicate the slipping issue under various driving conditions.
6
Check the transmission control module (TCM) for proper operation and software updates.
