Beijing Hyundai Elantra 1.8 sedan car, where is the best transmission repair, automatic transmission equipped FA4A42, mileage of 67000km, users reflect the existence of the car shift shock failure, transmission in 1 liter block 2 block most obviously. Shanghai Bao Xing is your fault analysis and repair program: the use of the engine diagnostic system was tested, the results also did not find fault memory. Considering the throttle position sensor signal voltage directly affects transmission shift, I view the data stream from the carefully observed when the engine is idling, throttle position sensor output voltage is 0.4V, the data properly. Later, the author of the stall test on the car, the engine stall speed is 2000r / min, in the standard range. Later, the author has been shifting to the transmission of learning operation, but the problem is still not resolved. At this point, it determined that the problem lies in the internal transmission. To enable users to reduce maintenance costs and reduce maintenance time, it decided not to remove the gearbox, but on car maintenance. So I removed the first body, of each of the control valve and accumulator work to be checked. Just check the pressure accumulator, the author found that LR, UD, 2ND and OD4 an accumulator pistons are tight, transmission repair, do not get out, and the surface is discolored, do you repair the transmission, use it a large force is required activities, 2ND accumulator situation is particularly serious. Under normal circumstances, the accumulator piston should be able to be easily removed by hand. Continue to check each of the control valve on the body, no jamming phenomenon, it seems that the problem is likely lies in the four accumulator because accumulator shift directly affects the ride. So we replaced the four accumulator, and for a new valve repair kits. Finally, in the cleaning of the transmission, the car after an oil change equipment retest, troubleshooting.
