Gear Selector Lever Assembly (Automatic gearbox - Jatco) (page 2 of 3)

There are seven selector lever positions: l P (Park) - prevents the vehicle from moving by locking the gearbox. l R (Reverse) - select only when vehicle is stationary and the engine is at idle. l N (Neutral) - no torque transmitted to the drive wheels. l D (Drive) - this position uses all five forward gears. Normal position selected for conventional driving. l 4 - this position uses 1st to 4th gears only. l 2 - this position uses 1st and 2nd gears only. l 1 - this position uses 1st gear only. l S/M (Sport/Manual - Steptronic) - this position uses all five gears as in 'D', but will shift up at higher engine speeds, improving acceleration. l + and - - movement of the selector lever in the +/- positions, when the selector lever is in the 'S/M' position, will operate the gearbox in manual (Steptronic) mode, allowing the driver to manually select all five forward gears.

The selector lever position is displayed to the driver on the LED module in the centre console and in the instrument pack and corresponds with the position of the selector lever. The LED module illumination and instrument pack display is determined by the selector and inhibitor switch assembly on the gearbox, with the exception of the 'S/M' LED and the 'Sport' instrument pack display which are operated by a hall effect sensor located on the sport/manual switch.

All vehicles with an automatic gearbox incorporate an interlock solenoid at the bottom of the lever, which, when the ignition switch is in position II, prevents the lever being moved from Park unless the foot brake is applied.

In some markets, the gear selector lever also incorporates a key interlock mechanism, operated by the selector lever and a Bowden cable connected to the ignition key barrel. The mechanism prevents the ignition key being removed from the barrel unless the selector lever is in the Park position. The mechanism also prevents the selector lever moving from the Park position until the ignition switch has turned from position 0 to position I or above.
