142 Data Parameters Transmission Parameters ENGINE TORQUE MAX __________________________________________ (range variable) Indicates the maximum engine torque that the TCM will allow on a V transmission. The TCM reduces engine torque required during shifts. GEAR POSITION _______________________________________________ (range variable) Indicates which gear the transmission is in. HILL FACTOR) _____________________________________________ (range 0 to 100%) Indicates the TCM calculation of driving conditions on M and N transmissions. When driving on level road (less than ±3½ degrees, the TCM will function in economy mode. When there is road resistance, such as wind load, towing, increased vehicle load or uphill driving (more than 3½ degrees, shift points change to provide more engine RPM and power. When road resistance decreases, such as going downhill, the TCM automatically selects a suitable lower gear. Engine braking is provided with the selector lever in D and reduces the need for braking when driving downhill. When road resistance returns to normal, shifting characteristic also return to normal.
