What it means
P07E2 is a generic powertrain code meaning the transmission control unit has detected an incorrect shift from 7th gear. The control unit compares input and output shaft speeds against the ratio expected for the commanded gear, and the ratio did not match during or after a shift out of 7th. The exact strategy and the gear it was shifting to depend on the transmission type and manufacturer.
Symptoms
- Gearbox warning light or malfunction message on the dash
- Harsh, delayed or flaring shift when changing down from or up out of 7th gear
- Engine revs rising without matching acceleration during a shift
- Gearbox dropping into a limp-home mode or locked in one gear
- Poor fuel economy or reduced performance at motorway speeds
- Juddering or shuddering at cruising speed
Possible causes
- Low, degraded or incorrect transmission fluid affecting hydraulic pressure and clutch engagementlikely
- Faulty shift solenoid or pressure control solenoid, or a sticking valve body componentlikely
- Faulty input or output shaft speed sensor, or a poor signal from itpossible
- Damaged wiring, corroded connectors or water ingress to the transmission harness or control unit connectorpossible
- Worn or slipping clutch packs or brake bands for the gears involved (internal mechanical wear)possible
- Outdated or faulty transmission control unit software calibration (only where the manufacturer has issued an update for this fault)rare
- Faulty transmission control unitrare
How to diagnose
- Read all stored and pending codes plus freeze frame data, noting gear, speed, load and fluid temperature when the fault set
- Check for other transmission, speed sensor or engine codes, as these can point to the root cause
- Check transmission fluid level, condition and smell, following the procedure for the specific gearbox (some are sealed and need a temperature-specific check)
- Inspect the transmission wiring harness and connectors for chafing, corrosion, fluid contamination and damage
- Use live data to compare input and output shaft speeds, and check the actual gear ratio against the commanded gear during a shift
- Test speed sensor signals and solenoid circuits for resistance, supply and signal against the manufacturer's specification
- Check for technical service bulletins or software updates relevant to the model and gearbox
- Carry out a road test or manufacturer-specified adaptation or pressure test to confirm slip or a hydraulic fault
How to fix
- Correct the fluid level or replace degraded fluid and filter using the specification and procedure for that gearbox
- Repair or replace damaged wiring and connectors, and clear any fluid contamination
- Replace a faulty speed sensor or shift or pressure solenoid after confirming it has failed
- Repair or replace the valve body or internal clutch components if wear or slipping is confirmed
- Apply a manufacturer-released control unit software update where one exists for this fault, then perform any required adaptation reset
Can I keep driving?
Medium severity
The car may be driveable, often in limp mode, but continued use with slipping or harsh shifts can cause further internal gearbox damage. Have it diagnosed soon and avoid heavy loads or towing until it is fixed.
