1 Answers
Automatic transmission fault diagnosis methods are: 1. After the engine is warmed up, shift into P or N gear, turn off the air conditioning, and check the idle speed. 2. Inspect the throttle position cable and sensor. 3. Check the quality of the automatic transmission fluid. 4. Shift into P or N gear and push the vehicle. 5. Check the P or N gear start switch. 6. Move the gear lever sequentially from P position to other positions to check if the shifting is smooth. The functions of the transmission are: 1. Change the transmission ratio to meet the traction needs under different driving conditions. 2. Enable reverse driving. 3. Interrupt power transmission. 4. Achieve neutral gear.
