Ford Fusion Transmission Problems & Overview

Something seems wrong with your Fusion? Let’s look at some of the most common Ford Fusion transmission problems, and see what you can do to get your car back on the road.

2006-2012 – First Generation

Designed to replace the midsize Ford Taurus, the first generation Fusion could be had with  a 160-hp 2.3L 4-cyl, or a 221-hp 3.0L V6. The smaller engine could be paired with either the Mazda G5M 5-speed manual, or the Mazda FNR5 5-speed automatic. V6 models were fitted exclusively with the Aisin TF-80 6-speed automatic. A 2010 facelift brought a host of improvements, including a new 175-hp 2.5L 4-cyl, a 240-hp version of the Duratec 3.0L V6, and the new Ford 6F35 6-speed automatic. Fusion Hybrid models used an Aisin CVT.

2013-Present – Second Generation

The second generation Ford Fusion was part of the new One-Ford global product strategy, which meant this one car could be sold in all markets. North American versions were powered by a number of different engines, including turbo 4-cylinder’s, a hybrid, a plug-in hybrid, and a V6. The 1.6L EcoBoost model was available with the Ford B6 6-speed manual, the other engines were paired with the 6F35 6-speed auto, the hybrids got the Ford HF35 CVT transmission, while the V6-powered Ford Fusion Sport got the 6F55.

Ford Fusion Technical Service Bulletins (TSB)

2013-2014 Ford Fusion – TSB 374584

Problem:

On Ford Fusions equipped with either the 1.5L or 1.6L, fluid can accumulate around the bottom of the transmission housing. Sticky, “honey colored” fluid is likely from excessive grease or rust-inhibitor that was applied during manufacturing. Less viscous fluid is likely to be engine oil, or automatic transmission fluid.

Solution:

If the fluid is determined to be grease or rust inhibitor, it can simply be drained, and the housing cleaned with brake cleaner. If the fluid is determined to be engine oil or ATF, further diagnostic procedures may be required.

2013-2014 Ford Fusion Hybrid / Ford Fusion Energi – TSB 14-0176 / 387601

Problem:

On Ford Fusion Hybrid models equipped with the Ford HF35 transmission, owners may experience a pronounced thumping, rubbing, or grinding noise coming from the transmission.

Solution:

This problem can be solved by replacing either the entire transmission, or the transfer shaft gear assembly. The transmission cooling system will also need to be flushed.

2010-2014 Ford Fusion – TSB 15-0079 / 379414

Problem:

Owners of some 2010-2014 Ford Fusion models equipped with the Ford 6F35 transmission, may experience a fluid leak coming from the left half shaft seal, due to premature wear to the transmission case bushing.

Solution:

To solve this issue, an updated case bushing, seal and half shaft will need to be installed.

One thought on “Ford Fusion Transmission Problems & Overview

  1. 2012 Ford Fusion SEL. Hangs in 2 or 3 gear way too long and then jolts into the next gear. 2 Dealerships have told me that this is consistent with the operation of the 6T35 transmission. Any thoughts?
