P0825 Gear Lever Push-Pull Switch (Shift Anticipate)
P0825 concerns a switch on the selector that reports pushing or pulling the lever – sequential + and – shifting – or the start of a shift movement, hence 'shift anticipate'. Its purpose: the control unit of an automated manual gearbox can prepare clutch and engine torque before the actual gear change is detected; a LuK patent describes such shift-intent detection, which reports intent when the lever signal exceeds a filtered, load-dependent reference and cancels on a reversal. A fault is typically a switch reporting 'pressed' without lever movement or never, implausible against the X/Y sensors. No manufacturer document with P0825 is available to us. Shift-intent detection is then off, gear changes are slower or sequential shifting is disabled.
Likely causes
Symptoms
- Delayed or jerky gear changes (automated manual)
- Sequential tapping not working
- Transmission warning in the cluster
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
