F4A51 transaxle Archives - Transmission Digest

A 2001 Mitsubishi Galant with an F4A51 transmission came into a shop here in Miami with a complaint of no forward movement. The complaint was verified, and the unit was replaced with a rebuilt transmission that matched in gear ratio. After a thorough road test the car was returned to the owner.

Now, That’s Odd!

We had such a case just recently. We field many calls regarding the Hyundai and Mitsubishi F4A40/50 series transmission. Usual complaints on this unit are that it’s in failsafe or there’s a 2-3 shift flare. But on one particular day, we received three tech calls in a row with an out-of-the-ordinary problem. Two were regarding a 2001 Dodge Stratus with a 3.0-liter V-6 engine, the other a 2002 Chrysler Sebring with the same 3.0-liter V-6 engine.
