Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Other Modes
Adaptation
The transmission control module (TCM) monitors each shift during all driving conditions to ensure consistent and smooth gear shifts. The control module does this by either lowering or increasing the hydraulic pressure used during the shift itself. The changed pressure levels are stored in the control module memory when the car has been switched off and are retrieved on start-up. This provides improved shifting comfort and increased service life.
Adaptation occurs when the following conditions have been met:
- Throttle opening is steady
- Oil temperature between 50 °C and 110 °C.
Temperature controlled lock-up
If the transmission temperature increases abnormally as a result of heavy load under high ambient temperature conditions, the torque converter lock-up function is activated as often as possible (temperature controlled lock-up). This reduces slippage and the generation of heat in the transmission. If the temperature is below +20 °C the lock-up function does not engage in order to increase the temperature of the oil more rapidly.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
