What it means

P0825 is the generic code for a fault in the gear lever push-pull switch circuit, also called the shift anticipate switch. This switch tells the control unit when the driver is pushing or pulling the gear lever, for example during a manual shift mode or a tip-style selector movement. The code sets when the signal from the switch is missing, stuck, implausible or does not match the lever position or other inputs. How the switch works and what the car does about it depends on the model and transmission type.

Symptoms

Warning light on, possibly with a transmission or gearbox warning message
Manual or sequential shift mode not responding or shifting erratically
Gearbox stuck in a fixed gear or defaulting to automatic-only operation
Delayed, harsh or unexpected gear changes
Gear lever position not shown correctly on the dashboard display

Possible causes

Faulty or worn gear lever push-pull switch or shift anticipate sensorlikely
Damaged, chafed or corroded wiring to the switch, including open circuit, short to earth or short to supplylikely
Poor connection at the switch or control unit connector, such as corrosion, bent pins or loose terminalslikely
Contamination or liquid ingress in the gear lever assembly, for example spilled drinkpossible
Mechanical wear or misadjustment of the gear lever or selector linkage so the switch is not actuated properlypossible
Fault in the transmission control unit or its softwarerare
Low battery voltage or poor earth causing a false signalrare

How to diagnose

Read all stored and pending codes and note any other transmission, gear selector or network faults
Review freeze frame data to see gear, vehicle speed and conditions when the code set
Check battery condition and charging voltage, and inspect main earth connections
Visually inspect the gear lever assembly for damage, wear or liquid contamination
Inspect the switch wiring and connectors for chafing, corrosion, bent pins and loose terminals
With a scan tool, watch the live switch status while moving the lever and check it changes cleanly in both directions
Check the switch circuit supply, signal and earth against the manufacturer wiring diagram for the specific model
Check for a relevant software update or technical bulletin for the vehicle and transmission

How to fix

Repair or replace damaged wiring and clean or re-terminate faulty connectors
Replace the gear lever push-pull switch or the complete lever assembly if the switch is not serviceable separately
Clean or dry out the lever assembly after liquid ingress and replace any parts that have been damaged
Adjust or repair the selector linkage and lever mechanism so the switch is actuated correctly
Correct battery or earth faults found during testing
Update the transmission control unit software only if an applicable update exists for a known fault, or replace the unit if it is confirmed faulty

Can I keep driving?

Medium severity

The car can usually be driven for a short time, but it may default to a limited shift mode or behave unpredictably, so have it checked soon. Stop driving if the gearbox will not select gears properly or shifts become harsh or unsafe.
