On the 2004-2012 Mitsubishi Galant, the 2004-2012 Galant used different automatics depending on engine and year. 2.4L four-cylinder cars have the F4A4B 4-speed. 3.8L V6 cars used the F4A5A 4-speed through 2007, and later V6 cars, including the GT and Ralliart, got a 5-speed automatic. Owners report harsh or flaring shifts, slipping, and in some cases a transmission that slips and won't shift into another gear until the car is turned off and restarted. One 2007 owner's car did this, and an independent mechanic found the transmission had failed and ordered a new one. A 2006 owner reported a stutter when first shifting into reverse, and a stutter in Drive that lasted as long as the car was cold. For 2004-2005 cars, Mitsubishi issued service bulletin 0523004 for a flare on the 2-3 upshift (engine revs rise without the car pulling). For 2004 cars it also issued bulletin 0423002, a service manual revision giving the procedure for resetting the transmission's learned values. Repairs range from a fluid service or valve body/solenoid work to a full rebuild or replacement, and replacement is expensive.

This issue also affects: Mitsubishi Eclipse, Mitsubishi Endeavor, Mitsubishi Lancer

Common Symptoms

Harsh shifting between gears
Engine flares (revs rise) on the 2-3 upshift
Transmission slipping under load
Won't shift out of one gear until the engine is restarted
Stutter when engaging reverse, or while driving with the car cold
Burnt transmission fluid

How to Fix

1) Check the fluid first: level, colour and smell. If the fluid is burnt, dark or full of debris, or there is metal in the pan, the transmission is probably worn inside and a fluid change will not fix it. 2) Have a shop read the stored transmission codes. Before you replace parts, confirm which transmission your car has, because the 2.4L, early V6 and later V6 use different units. 3) On a 2004-2005 car with a 2-3 shift flare, ask a Mitsubishi dealer about TSB 0523004. On a 2004 car, ask them to reset the learned values using the TSB 0423002 procedure after any fluid, valve body or solenoid work. 4) If the car slips, or sticks in one gear until you restart it, get it diagnosed before you rely on it. Ask a dealer to run the VIN for any open campaigns. One repair guide gives these rough US costs for Mitsubishi automatics in general, not the Galant specifically: about $180-400 for a fluid service at an independent shop, about $600-1,800 installed for valve body or solenoid work, and about $2,500-5,500 for a rebuild or replacement.
