Keywords: Volkswagen Passat car does not go public transmission repair Volkswagen Passat transmission repair transmission fault models Information: PasstB51.8t Engine: 01V Type Transmission: 5HP-19 Mileage: 260,000 km Symptom: Volkswagen Passat forward gears properly, hanging Reverse fuel door can not limp, fuel door would not take the car, after a loose throttle pedal will feel the impact of a combination of reverse instantly. According to the customer describes the public gearbox overhaul a month ago, had never noticed this phenomenon before, most recently when reversing uphill slope was found on a reverse did not force, fuel door still slip slope. Troubleshooting: test found that clients describe the problem is true, no diagnostic trouble codes stored records detection, reverse the data stream is not found in unusual circumstances, the instrument displays the reverse is also normal, check the gearbox oil without burning phenomenon, the oil level is normal. You can determine whether the fault was initially reverse the oil pressure relief, normal reverse power transmission line known to pass the corresponding components: small sun wheel drive clutch B, D brake brake carrier, brake G braking additional sun gear. Symptom seen by the higher engine revolutions reverse the weakness, the more powerful relief. Analysis of the actuator piston relief if it is, the throttle should be able to improve the hydraulic supply to compensate the loss of hydraulic leaks, fuel door should be able to take the car, so this possibility can be ruled out, then the problem Watch valve control circuit section, split Solution D position control valve body pressure accumulator pressure accumulator cover gasket found sclerosis, and fixed the pin for wear. When the engine speed increases a large amount of gearbox oil pump, a pressure accumulator in a short period of time greater coefficient of expansion, resulting in large amounts of hydraulic leak, resulting in a real shift into lower hydraulic brake piston D, the carrier can not promptly fixed, the power can not be successfully transmitted to the additional planetary bodies, there does not take the car reverse fuel door phenomenon. Therefore, this fault can lead to initial recognition fuel door hanging reverse Troubleshooting: Replace the valve body assembly, commissioning OK above information is provided by Teng Hua transmission company, For reprint please indicate the source.
