Cheng Jing automatic transmission 12 slow speed increase o

The slow upshift of automatic transmission should be caused by improper adjustment of throttle cable or throttle position sensor.

There are many factors that cause slow gear shifting, such as excessive clutch wear in the gearbox, blocked gearbox oil filter, oxidation speed change of gearbox oil, gearbox valve body failure, engine failure leading to insufficient power, etc. , which may have an impact on the shift comfort of the gearbox. It is suggested that professional technicians should analyze and diagnose faults by reading relevant data streams with the help of diagnostic equipment of 4S shops of related models, so as to judge faults more accurately and eliminate them.

Oil circuit failure, broken oil pipe or loose joint, and insufficient oil pump pressure will all lead to poor oil supply and affect acceleration; Circuit failure, high water temperature or damaged temperature sensor will all affect the acceleration performance, and the blockage of three-way catalytic device or the problem of oxygen sensor will also lead to poor engine acceleration.
