P0750 on Mitsubishi by model: symptoms, diagnosis and fix
The 4-speed automatic transmission in the 3rd generation Eclipse (particularly V6 GT models) is prone to premature failure. The transmission develops harsh shifting, slipping, and eventually fails completely, often due to overheating and worn clutch packs.
Common Symptoms
- Harsh or delayed shifts
- Transmission slipping in higher gears
- Burnt ATF smell
- Transmission overheating warning
How to Fix
Install an auxiliary transmission cooler to prevent overheating. Change the ATF every 30,000 miles. When the transmission fails, consider a quality remanufactured unit from a Mitsubishi specialist.

Frequently asked questions
What does P0750 mean on a Mitsubishi?
P0750 stands for "Shift Solenoid A Malfunction." This code indicates the transmission control system detected a malfunction in shift solenoid 'A', one of the electrically operated valves that direct hydraulic fluid to engage gears. The computer commands these solenoids to control upshifts and downshifts, and it monitors their circuits and the resulting gear changes. When solenoid A doesn't respond electrically as expected — or the resulting shift doesn't happen correctly — this code is set. You may notice harsh, delayed, or missing shifts, or the transmission may enter a fail-safe (limp) mode. On Mitsubishi it is documented across 1 model: Eclipse.
What are the most common causes of P0750?
The most common causes of P0750 are: Failed or stuck shift solenoid A, Open, shorted, or chafed solenoid wiring, Corroded or loose transmission connector, Low, dirty, or degraded transmission fluid, Clogged solenoid or valve body passages, Internal valve body or hydraulic fault, Faulty transmission control module (TCM).
