The upshift of Fat Fish 3.0 gearbox is delayed, and the flameout will return to normal.

The slow upshift of automatic transmission may be caused by the failure of shift solenoid valve.

If it is an accidental fault, it can generally be solved by eliminating the fault code or upgrading the program. If the fault is not accidental, the corresponding accessories need to be replaced.

The slow upshift of the gearbox means that the upshift speed of the automobile is obviously higher than the standard value, and the engine speed is slightly higher before the upshift, so it is necessary to take the operation method of upshift of the accelerator pedal in advance (that is, release the accelerator pedal for a few seconds and then press it) to make the automatic gearbox upshift to a high gear or an overspeed gear. The main reasons for the slow upshift of the gearbox are: the governor is stuck, the forced downshift switch is short-circuited, the computer or sensor is faulty, the throttle position sensor is damaged, the pre-tightening force of the governor spring is too large, and it is vacuum.
