Is it related to the throttle that the Elantra automatic transmission sometimes does not rise?

Is related. For example, if you are in a hurry to refuel, the computer will detect the throttle opening signal and compare it with the data of the computer itself, and judge that you need more torque now, which will delay the upshift. Similarly, if the throttle signal fails, it will definitely affect the upshift of the automatic transmission. The jump time of the automatic gearbox is judged by the computer according to the speed signal and the engine load signal, and the engine load signal depends on the size of the throttle; Under normal circumstances, at the same speed, the bigger the throttle, the later it jumps, and the smaller the throttle, the earlier it jumps. Therefore, when the speed is about to reach the upshift point, you can loosen the throttle and upshift the gearbox in advance, which can achieve the effect of saving fuel. There are also oil temperature sensors, hydraulic torque converters and valve bodies, which have an impact on the upshift. I hope it helps you. Please accept it if you are satisfied.
