Common Ford Fusion Transmission Problems

Here we outline a few common problems concerning transmissions that Ford Fusion drivers face during driving.


  • The G5M is overall a fine transmission, and the gears also hold up. However, the shift forks do not like to get abused.
  • The forks will last a long time and do not get blended, provided that the drivers remain gentle with the shifter.
  • You may require to change forks often, nearly every five races, given that many people drive the exact vehicle. It is evident because you can’t expect everyone to treat it sensitively.
  • The hard launches damage the differential. Otherwise, gear sets and the differential hold up fine.
  • You may require to disassemble the transmission when you want to swap bell housings.


  • A driver may face overdrive clutch burning in the case of an aggressive driving style.
  • You may also need to replace the complete set of a filler block and linings friction clutches during a considerable repair.
  • Moreover, you may also require the clearance of the valve body. It will help improve the cooling of the gearbox and scientific grease.


  • The 6F35 transmission may reveal a slight shudder on two-to-three upshifting, although it is decent most of the time.
  • When manually shifting the shift lever, a driver may experience a jolt.
  • Oil starvation can lead to clogging of the hydraulic plate.
  • It is essential to spot problems timely regarding clutch slips, oil pressure, and torque converter. It prevents you from costly replacement of the valve body, solenoids, and worn-out hardware.


  • A burning smell often hints that something is wrong with the transmission.
  • On some occasions, cars with the TF-80 transmission may slip out of gear.
  • If there is a long slip, it may also prevent manual shifting.
  • Leaking is another problem with the transmission. Going low on fluid may indicate the given issue.
  • It may also have a harsh shift into Drive. Although the intensity of harshness may not be the same, it may also occur in reverse.

Differences Between Transmissions

The G5M is a five-speed automatic transmission designed to offer short-throw shifting, give the four-cylinder engine line-up a crisp, and ensure low shifting effort in sports car style. It also allows quick-shifting because it has a high power synchronization feature. The given innovation feature also provides precision engagement and convenient shift effort for the first and second gears.

The FNR5 is a 5-speed automatic transmission. Under normal circumstances, it changes forward gears without the requirement of drive input, and it handles up to 25 ft-lbs of torque.

The 6F35 is a 6-speed automatic transmission. It boasts multiple innovative features that provide quieter operation, better fuel economy, and reduced NVH (noise, vibration, and harshness). For the record, it is a front-wheel-drive transmission. It is one of the transmissions that represents an all-encompassing strategy to deliver sustainable solutions for customers.

The TF-80 is a 6-speed automatic transmission. It fits in the same space as a manual transmission. When it comes to its measurements, it weighs 90 kg and 358 mm in length. The presence of both a Ravigneaux gear set and a 5-pinion planetary gear set makes it unbelievably compact and light. It is a sophisticated computer program that manages the shifting of gears. The program essentially oversees a clutch-to-clutch actuation. Besides, it is considered a maintenance-free gearbox because it uses proprietary transmission fluid.

Transmission Fluids And The Ford Fusion

We suggest resolving the issues as soon as possible to ensure the seamless running of the transmission. While talking about transmission fluids, many experts in the field suggest changing it between 30,000 miles and 60,000 miles. Nevertheless, bear in mind that all gearboxes do not entertain the same fluid. For your help, we provide you with the source below. It will get you the one suitable for your transmission.
