What it means

P0772 is the generic code for Shift Solenoid E stuck on. The transmission control unit has commanded the solenoid off, or expected a certain gear or pressure outcome, but the monitored result shows the solenoid is still acting as if it is energised or open. Which gears and functions Solenoid E controls varies by transmission, so the exact effect depends on the model.

Symptoms

Gearbox warning light or engine management light on
Transmission stuck in one gear (limp mode)
Harsh, delayed or flared gear changes
Wrong gear selected or unexpected shifts
Missing or incorrect gear ratio for a particular gear
Poor fuel economy or reduced performance

Possible causes

Shift solenoid E mechanically stuck due to debris, varnish or wearlikely
Dirty, degraded or contaminated transmission fluid, or a blocked filterlikely
Low fluid level or incorrect fluid type causing pressure problemspossible
Wiring fault such as a short to power or chafed loom between solenoid and control unitpossible
Faulty or corroded connector at the solenoid or internal transmission harnesspossible
Worn valve body or internal hydraulic fault affecting the circuitpossible
Faulty transmission control unit or outdated softwarerare

How to diagnose

Read all stored codes and freeze frame data, noting gear, temperature and speed when the fault set, and look for related solenoid or ratio codes
Check transmission fluid level, condition and smell against the manufacturer's procedure, as this varies by model and some units are sealed
Inspect the wiring and connectors to the transmission for damage, corrosion, fluid ingress or chafing
Check for any manufacturer technical bulletins or software updates relevant to the model and transmission
Using live data, command the solenoid and compare the commanded state with the reported state and gear ratio
Measure the solenoid circuit for short to power or ground and check solenoid resistance against specification
Check line pressure and perform any stall or pressure tests as the manufacturer specifies
If the circuit and fluid are sound, inspect the solenoid and valve body for sticking or wear

How to fix

Replace the transmission fluid and filter with the correct specification if it is dirty or degraded, and correct the level
Repair or replace damaged wiring or connectors in the solenoid circuit
Clean or replace Shift Solenoid E if it is sticking
Repair or replace the valve body if internal wear or blockage is found
Apply any available control unit software update if an outdated calibration is a known cause for that model
Repair or replace the transmission control unit only after other causes are eliminated

Can I keep driving?

Medium severity

The car may be driven carefully a short distance if it shifts normally or is in limp mode, but get it checked soon. Continued driving with a stuck solenoid can overheat the gearbox and cause further internal damage.
