A mileage of about 120,000 km, equipped with a V6 3.5 L engine and U151E automatic transmission 2005 Guangqi キセノンランプToyota Highlander sport utility vehicle. The user reflect: the car slow action.
Maintenance personnel after the pick-up test, found the car in terms of the shift into forward gear or reverse gear, release the brake pedal, the vehicle can travel. Vehicles in the acceleration phase, 2 block liter block Chuang car serious. X431 Check the transmission fluid smell the strong odor of char, rather than. Detect transmission control unit, found no fault codes.
As the car forward gears and reverse gear there was no slow action force, so maintenance personnel decided to check transmission hydraulic. Measuring the transmission when the engine idling, oil pressure, significantly lower. The working hydraulic disorders plus oil deterioration satisfy the conditions for a transmission overhaul.
After the disintegration of the transmission, found that the overdrive clutch CO (Figure 1) and 2 block brakes B1 burned. Burned element friction sheet shedding serious, and exfoliated portion of friction material have been glued together. ELM327Longer usage time speeding vehicle driving gear clutch CO 2 gear clutch B1 uses a higher frequency, so the two shift elements the first damage is understandable. Legend to the measurement results, before dismantling transmission speculated that this low hydraulic oil pressure related.
Check the transmission oil pump, intact. The further check hydraulic control valve body, found the main regulator column Fonseca stagnation,車LEDライト apparently the root cause of this is the fault. But why this valve will be catching it? Analysis Body long withstand high temperatures, and the cooling system of the engine and transmission related to poor.
Troubleshooting: replace the engine and transmission, radiator, renovation of the torque converter in accordance with the standard transmission overhaul. Commissioning confirm troubleshooting.
