What is the reason why the Teana does not move when idling in reverse gear?
2 Answers
Teana does not move when idling in reverse gear for the following reasons: Functional comprehensive failure: Involving the clutch, gearbox and drive axle, the fault location should be determined first during diagnosis, and the condition of the two wheels can be checked first. The order of diagnosis is generally from the drive wheels forward through the rear axle to the drive shaft and then to the gearbox, and finally to the clutch. If the drive shaft rotates, but the car does not move forward, the fault is in the rear axle. Lift the rear axle and rotate one rear wheel. If the other rear wheel rotates in the opposite direction but the drive shaft does not rotate, it means that all the rivets of the differential bevel gear are cut off. If the other rear wheel does not rotate, the half shaft should be disassembled and inspected to see if it is broken. Gearbox failure: Remove the gearbox cover and check whether the gear shift fork of the gearbox is broken and whether the guide block fixing screws are loose. If the above checks are normal, perform a gear engagement test. If the second shaft does not rotate in a certain gear, it means that the half-round key of the gear is cut off. If the second shaft rotates in direct gear but does not rotate in other gears, it means that the support bearings at both ends of the intermediate shaft are disassembled and the intermediate shaft falls.
I also encountered this issue when driving my Teana. The car wouldn't move when shifting into reverse, which was particularly frustrating at idle. The main causes could be transmission problems, such as insufficient or aged transmission fluid affecting power delivery, or torque converter failure preventing effective power output to the drive wheels at idle. Sensor malfunctions, like incorrect signals from the gear position sensor, can also cause the computer system to misjudge. Don't ignore this—failure to move at idle can easily lead to rolling accidents, especially on slopes or in tight spaces. It's recommended to first check the transmission fluid level and color—pull out the dipstick to see if it's between min-max, and replace the fluid immediately if it's dirty. Regular maintenance should include periodic transmission fluid changes, with a professional inspection generally recommended every 40,000 kilometers to prevent major issues.
