Automatic

1. It doesn’t shift.
1. The shift lever makes a normal movement and the transmission shift lever moves also but the gear doesn’t change: Go to step 3.a.
2. The shift lever does make a small movement and the shift cable gets tensioned (pull movement) or pressured (push movement), but the transmission shift lever doesn’t move: Go to step 2.g.
3. The Auto Shifter shift lever doesn’t move at all: Go to step 2 .
2. The shift lever of the Auto Shifter doesn’t move at all.
1. Is ignition on? If not, switch ignition on.
2. Does the board receive ignition power on connector J1, between pin 3 (positive) and pin 1 (negative)? If not, check the board fuse (at least 1 A) and the board power and ground wiring. (See also section 4.4.1  Power Wiring of the installation manual for more info.)
3. Does the board receive motor power on connector J1, between pins 6 and 7 (positive) and pins 8 and 15 (negative)? If not, check the motor fuse (40 A) and the motor power and ground wiring. (See also section 4.4.1  Power Wiring of the installation manual for more info.)
4. If the transmission is in park and you are attempting a “shift towards park”, try a “shift towards forward”. Shifts towards park are not possible in park.
5. If the transmission only shifts into positions P,R,N,4,3,2 and you have a 4 speed automatic transmission and can’t get into Manual 1^st position, check the configuration of the number of gears. (See also 3.5 Transmission Tab of the installation manual for more info.)
6. If the transmission is in Manual 1^st position (automatic transmissions) or 3^rd or 4^th gear (3/4-speed manual shift automatic transmissions), the number of gears is correctly configured (see “Number of forward gears”, 3.5 Transmission Tab of the installation manual for more info) and you are attempting a “shift towards forward”, try a “shift towards park”. “Shifts towards forward” are not possible in the “highest” gear position.
7. Try disabling all safety features (neutral safety and brake safety; see also 3.8  Shift Safety Tab and 4.4.3  Brake Switch of the installation manual for more info). If it works now, verify how the safety feature(s) that you just disabled are supposed to work. Verify the switches associated to the safety features. Maybe a switch is stuck or not properly wired or configured?
3. The shift lever of the Auto Shifter makes a small movement and the shift cable gets tensioned (pull movement) or pressured (push movement), but the transmission shift lever doesn’t move.
1. Verify the shift direction. See also section 3.7  Shift Setup Tab of the installation manual for more info.
2. Make sure the transmission shift lever can move in the desired direction. (Disconnect the shift cable from the Auto Shifter shift lever and try to move the transmission shift lever manually.)
4. The shift lever of the Auto Shifter makes a normal movement and the transmission shift lever moves but the gear doesn’t change.
1. Verify the adjustment of the shift cable (see also section 4.5  Initial Configuration, Finalization and Test , steps 6 and 10 of the installation manual for more info).
2. Verify especially the detent position calibration (see sections 3.5  Transmission Tab and 3.6  Custom Tab of the installation manual for more info).
5. The transmission changes gears but the gear display is not functioning correctly.
1. Verify that the three wires that come from the position sensor on the transmission are connected to the correct wires of the display unit.

1. I executed the MasterShift™ Auto Shifter Configuration software but I can’t configure the device.
1. The first tab page shows “Serial port not connected” in red: Go to step 2.
2. The first tab page shows “Serial port connected” in black and “Auto Shifter not found” in red: Go to step 3.
2. I can only access the first tab page of the MasterShift™ Auto Shifter Configuration software and it shows “Serial port not connected” in red.

3. I can only access the first tab page of the MasterShift™ Auto Shifter Configuration software and it shows “Serial port connected” in black, but “Auto Shifter not found” in red.
1. Verify that the Auto Shifter device is powered (both motor and board power; see 4.4.1 Power Wiring of the installation manual for more info). Usually that requires the ignition switch to be on.
2. Make sure you are using the serial cable that came with the Auto Shifter. This is not a standard PC serial cable. (A standard 9-pin male-female straight through wired serial cable may be used to extend the Auto Shifter cable, but not to replace it.)
3. Try to reconnect: close the application and re-open it.
