316 STARTING AND OPERATING "3" (Drive) - 4-Speed Transaxle This range eliminates shifts into "D" (Overdrive). The transaxle will operate normally in 1st, 2nd, and 3rd while in this range. The "3" (Drive) range should also be used when descending steep grades to prevent brake system distress. NOTE: Using the "3" (Drive) range while operating the vehicle under heavy operating conditions will improve performance and extend transaxle life by reducing excessive shifting and heat build up. "L" (Low) - 4-Speed Transaxle This range should be used for engine braking when descending very steep grades. In this range, upshifts will occur only to prevent engine overspeed while downshifts occur earlier than other gear range selections. CAUTION! If the transaxle operating temperature exceeds acceptable limits, the vehicle computer will override "D" (Overdrive) and "5" range (for 6-speed AutoStick transaxle) and "3" range (for 4-speed auto transaxle) by changing shift points. This is done to prevent transaxle damage due to overheating. Reset Mode - Electronic Transaxle The transaxle is monitored electronically for abnormal conditions. If a condition is detected that could cause damage, the transaxle automatically shifts into 2nd gear (3rd gear for 6-speed). The transaxle remains in 2nd gear (3rd gear for 6-speed) despite the forward gear selected.
