Floor Shift
The E-Shifter:
- communicates with the Transmission Control Module (TCM) via a Controller Area Network (CAN).
- incorporates a solenoid that allows the lever to be locked for purposes of Brake Transmission Shift Interlock (BTSI) function.
- lever-lock function is controlled electronically by the TCM via CAN message, and mechanically by the release trigger on the knob.
- indicates the selected/non-selected gears provided via illumination of PRNDM+- characters on knob.
- lever-position feedback is provided via mechanical detents, which also keep the lever in the desired position.
- communicates driver requests for transmission gear changes without a mechanical connection.
- is comprised of an upper knob and a lower base, which can be serviced separately.
- on some models, may have steering wheel-mounted paddle shifters available. Refer to SWITCH, REMOTE RADIO, DESCRIPTION .
The Electronic Shifter (E-Shifter) offers (P, R, N, D, M) modes of function.
The M selection (manual mode) is engaged by moving the shift-lever sideways to M. Requests to up/down shift are achieved by moving the lever fore/aft once in the manual position.
The 8HP45/845RE automatic transmission is operated with the help of an E-Shifter located in the floor console. E-shift or "Shift by Wire" is a vehicle level system that electronically performs the function of current mechanical shifter/linkage/transmission hardware. The E-Shifter is an electronic switch/module using CAN messaging to communicate driver requests for transmission gear changes. The use of an E-Shifter eliminates the system linkage & mechanical connection to transmission park pawl & sprag for normal operation. There are four positions to which the selection lever can be shifted: P, R, N, D/M+-.
In addition there are integrated paddle shifters at the steering wheel with allows the operator to manually chose gears as long as they comply with engine speed parameters.
