Diagnostics on the go
1. Acceleration test: Check for smooth and uniform acceleration in all speed ranges.
2. Brake test: Check whether the transmission slips under hard braking.
3. Gear shift test: Pay attention to the smoothness of gear shifting under different loads.
4. Torque Converter Performance Test: Listen for any buzzing or rattling sounds from the torque converter when shifting gears.
5. Leak test: Check for oil leaks from the gearbox.
Parking lot diagnostics
1. Checking the fluid level: Check the transmission fluid level and its condition (color, smell, presence of metal particles).
2. Check Electronic Systems: Use a diagnostic scanner to read transmission-related trouble codes.
3. Mechanical Inspection: Remove the transmission pan to inspect the friction discs, steel plates and other mechanical parts for wear or damage.
4. Check Solenoids: Check the operation of the solenoids that control fluid flow in the transmission.
5. Checking the hydraulic module: Check the functionality of the hydraulic module, which controls the hydraulic pressure inside the transmission.
Additional Tips
* Before diagnostics, warm up the engine and gearbox.
*Use the correct transmission fluid recommended by the manufacturer.
*Consult a qualified mechanic if you have difficulty diagnosing or repairing your transmission.
* Maintain your transmission regularly according to the manufacturer’s recommendations to prevent future problems.
