Transaxle Function

The 41TE provides smooth clutch-to-clutch shifts for all gear changes. This is accomplished by reading the input and output speeds over 140 times per second, along with other inputs. This shift strategy is referred to as adaptive control. Adaptive control provides for the precise friction element control needed to make smooth shifts. The TCM learns the release rate of the releasing element and the apply time of the applying element that it is controlling. It also learns the rate at which the apply element builds pressure sufficient to begin making the speed change. It also adapts to any changes that occur with age or environment.

Once the TCM analyzes the inputs it receives, it sends output commands to the hydraulic/mechanical portion of the transaxle. Similar to other transaxles, the 41TE uses hydraulically-applied clutches to shift a planetary gear train.

Upshifts are provided from 1st or 2nd to 3rd gear at peak engine speeds if the accelerator is pressed. This provides engine over-speed protection and maximum performance.
