NISSAN CVT TRANSMISSION RESET FREE

This is why many vehicle manufacturers claim to have maintenance free transmissions with lifetime fluids in them. It is because of this misconception that there are misleading articles that guide people on resetting transmissions by putting key in ON position and pressing down the throttle.Īdaptive transmission function makes the transmission to last longer, enables the use of transmission fluid for a longer period, reduces frequency and cost of maintenance and improves shift feel and comfort.Īdaptive transmissions make maintenance free operation of the transmission possible. This shift pressure and timing in the valve body of the automatic transmission controls the application of the clutches.Īdaptive transmission function should not be confused with another type of vehicle adaptation which is throttle adaptation that has more to do with how responsive the throttle is, based on driving style. Two important parameters in the operation of an automatic transmission are shift pressure and shift timing. Through artificial intelligence and machine learning, transmissions can learn and make adjustments to stored values without those values being explicitly programmed into the transmission's computer (Transmission control unit or engine control unit). The values can also change when a transmission's component or fluid is replaced. This learning process is continuous as the components and fluid age until the limit is attained. What adaptive transmissions do is to keep learning the shift pressure and timing values and adjust them accordingly by using the new values for the next application of shift pressure and timing. The transmission control unit automatically does this adjustment and store it in its memory continuously. Because of changes in the properties of the fluid, like viscosity and so on, and also due to changes in the tolerance of the internal parts, the fluid pressure and timing changes. This shift pressure and timing in the valve body of the automatic transmission controls the application of the clutches.Īs automatic transmissions age, their internal parts wear and the transmission fluid also wears out due to heat and sediments. Through artificial intelligence and machine learning, transmissions can learn and make adjustments to stored values without those values being explicitly programmed into the transmission's computer (TCU or ECU).
