What it means

P07E0 is a generic powertrain code meaning the transmission control unit has detected an incorrect shift from 5th gear. The control unit compared the commanded gear with the actual gear ratio, worked out from input and output shaft speeds, and saw that the shift did not complete as requested. The exact trigger and the gears involved vary by transmission type and model, so check the manufacturer's data for the vehicle.

Symptoms

Harsh, delayed or flaring shift when changing out of 5th gear
Transmission stuck in a gear or dropping into limp mode
Engine revs rising without matching road speed during a shift
Gearbox warning light or malfunction indicator lamp on
Poor fuel economy or reduced performance

Possible causes

Low, degraded or contaminated transmission fluidlikely
Faulty shift solenoid or clutch pressure control solenoidlikely
Wiring or connector fault in the transmission harness, or poor earth or supplypossible
Faulty input or output shaft speed sensor giving a wrong ratio readingpossible
Worn clutch packs, or valve body wear causing pressure losspossible
Outdated transmission control unit software or a faulty control unitrare

How to diagnose

Read all stored and pending codes and the freeze frame data, noting gear, road speed, fluid temperature and load when the fault set
Check for other transmission, speed sensor or engine codes, as these can point to the root cause
Check the transmission fluid level and condition, following the manufacturer's procedure, as some units are sealed and need a specific temperature
Inspect the transmission wiring harness and connectors for damage, corrosion, fluid ingress or chafing
Check battery voltage and the charging system, as low voltage can upset solenoid control
Use live data to compare input and output shaft speeds and the commanded and actual gear during a road test
Test solenoid and speed sensor resistance and signals against the manufacturer's specification
Check for relevant technical service bulletins and software updates for the model and transmission

How to fix

Correct the fluid level or replace the fluid and filter with the specified type if it is degraded or contaminated
Replace a faulty shift or pressure control solenoid, or the affected valve body component
Repair or replace damaged wiring, connectors or earth connections
Replace a faulty input or output shaft speed sensor
Overhaul or replace the transmission if there is internal clutch or hydraulic wear
Update the transmission control unit software if an outdated calibration is a known cause for the vehicle

Can I keep driving?

Medium severity

The car can usually be driven gently for a short time, but the fault should be fixed soon. Continued driving with incorrect shifts can cause clutch slip and expensive internal damage, so stop if the gearbox goes into limp mode with harsh shifts or slipping.
