SERVICE INFORMATION
When the PCM detects a malfunction that turns on the MIL, the D indicator, or both, it can revert to a backup mode or "limp home" mode. This mode differs depending on the A/T design, the cause of the malfunction or DTC, or both.
When you test-drive a vehicle, make sure you clear all A/T DTCs first. You cant evaluate the A/T if the MIL, the D indicator, or both indicators are on.
In backup mode, some A/Ts let you manually shift while others only let you shift to certain gears that apply to its particular backup mode. Here are some common symptoms you get in backup mode:
- Harsh upshifting and downshifting
- Vehicle starts in 2nd gear and then shifts to 4th gear
- Vehicle starts in 2nd gear and then shifts to 3rd gear
When an A/T is in backup mode, customers commonly complain about low power or lousy acceleration because the vehicle starts in 2nd or 4th gear.
