Driving higher speeds causes the transmission to shift to a lower gear, and will shift to 1 (Low) after vehicle decelerates to the proper speed. Forced Downshifts (Overdrive) or Drive (O/D OFF) when To gain acceleration in passing another vehicle, push the accelerator to the floor. The transmission will downshift to the appropriate gear: third, second or first gear. Shift strategy (4R100 automatic transmission) To account for customer driving habits and conditions, your 4R100 automatic transmission electronically controls the shift quality by using an adaptive learning strategy. The adaptive learning strategy is maintained by power from the battery. When the battery is disconnected or a new battery is installed, the transmission must relearn its adaptive strategy. Optimal shifting will resume within a few hundred kilometers (miles) of operation. If the shift quality does not improve within a few hundred kilometers (miles) of operation, or if the downshifts and other throttle conditions do not function normally, see your dealer or a qualified service technician as soon as possible. MANUAL TRANSMISSION OPERATION (IF EQUIPPED) Using the clutch Vehicles equipped with a manual transmission have a starter interlock that prevents cranking the engine unless the clutch pedal is fully depressed. 117
