What it means

P075E is a generic powertrain code meaning the transmission control module has detected an intermittent fault in the Shift Solenoid G circuit. The module saw the solenoid's electrical signal or feedback drop out, spike or behave erratically at times rather than staying faulty all the time. Which gear or function solenoid G controls depends on the make, model and gearbox.

Symptoms

Gearbox warning light or malfunction indicator lamp on
Occasional harsh, delayed or flared gear changes
Gearbox briefly dropping into limp mode, then returning to normal
Gear stuck in one ratio now and then
Poor fuel economy or erratic shift points
Fault that comes and goes with temperature or vibration

Possible causes

Loose, corroded or damaged connector at the gearbox or transmission control modulelikely
Chafed, broken or intermittently shorting wiring between the solenoid and the control modulelikely
Shift Solenoid G failing internally, with an intermittent open or short in its coillikely
Internal gearbox wiring loom or connector fault (often part of the valve body assembly)possible
Contaminated, degraded or low transmission fluid affecting solenoid operationpossible
Low battery voltage or poor earth connection causing erratic solenoid supplypossible
Faulty transmission control module or outdated softwarerare

How to diagnose

Read all stored and pending codes and note freeze frame data such as temperature, speed, gear and voltage when the fault set
Check battery condition and charging voltage, and inspect main earth connections
Inspect the gearbox connector and wiring for chafing, oil ingress, corrosion, bent pins and poor terminal tension
Check the transmission fluid level, condition and smell, following the manufacturer's procedure for that gearbox
With a scan tool that can monitor live data, watch solenoid commanded status and feedback while wiggling the harness and connector
Test the solenoid circuit for continuity, short to earth and short to supply, and measure the solenoid resistance against the specification for that model
Check for relevant technical bulletins or software updates for your specific vehicle and gearbox
If wiring and solenoid test good, investigate the internal loom, valve body and control module

How to fix

Repair or replace damaged wiring and clean or replace corroded connectors and terminals
Replace the faulty Shift Solenoid G or the solenoid pack or valve body assembly, depending on how the gearbox is built
Replace the internal gearbox harness or connector if it is found faulty
Correct the fluid level or service the gearbox with the correct specification fluid and filter where the manufacturer allows
Repair battery or earth faults to restore stable supply voltage
Update or replace the transmission control module only if testing shows it faulty or an updated calibration is a known fix

Can I keep driving?

Medium severity

The car can usually be driven gently for a short time, but intermittent harsh shifts or limp mode can occur and continued use may damage the gearbox. Get it diagnosed soon and avoid heavy loads or towing meanwhile.
