{Working Solution} How To Fix Ford FMX Transmission Problems?

Last Updated on April 2, 2023 by Robert Wilson

The Ford FMX transmission is a three-speed automatic transmission that was used in various Ford vehicles from 1968 until 1979. The FMX was introduced in 1968 and used in both front- and rear-wheel drive cars.

Despite its relatively short run, the FMX transmission was plagued with problems that continue to affect owners of vintage Ford vehicles today.

If you’ve been driving a Ford truck with an FMX transmission, you may have noticed some problems. The good news is that Ford is aware of the issue and has issued a recall. The bad news is that the recall affects over 1 million vehicles and could take months to fix.

The main problem seems to be with the transmission’s torque converter. This part helps to convert the engine’s power into torque, which is then sent to the wheels. However, on some trucks, the torque converter isn’t working properly.

This can cause the engine to rev up without actually moving the truck forward. In some cases, it can also cause the truck to move unexpectedly when in park or neutral. Ford says that it will begin repairing trucks affected by this recall in February 2020.

However, due to the large number of vehicles involved, it could take several months for all repairs to be completed.

Ford FMX Transmission Not Shifting (Solved)

If you’re having trouble with your FMX transmission not shifting, there are a few things you can check.

First, make sure that the transmission is in park or neutral. If it’s not, the problem could be as simple as a loose shifter handle.

Another thing to check is the fluid level. If the fluid is low, it could be causing the transmission to slip.

Make sure to check the owner’s manual to see what kind of fluid should be used and how often it should be replaced.

If neither of those solutions solve the problem, it’s likely that there is an issue with the transmission itself. It’s best to take it to a mechanic or Transmission specialist for diagnosis and repair.

Ford FMX Transmission Reliability

The FMX transmission was introduced by Ford in 1968 and was used in a wide variety of vehicles including the Mustang, Bronco, Pinto, LTD, and Thunderbird.

It is a 3-speed automatic transmission with a torque converter. The FMX is a good transmission for most applications but there are some things to keep in mind if you are considering using one.

One issue that can arise with the FMX is excessive wear on the planetary gears. This can be caused by improper lubrication or too much power being applied to the transmission.

If you are going to use an FMX in a high performance application, it is important to make sure that the transmission is properly lubricated and cooled.

Another potential problem with the FMX is that it does not have an overdrive gear. This means that fuel economy will suffer at higher speeds.

What Years Did Ford Use FMX Transmission?

The FMX transmission was used in Ford vehicles from 1968 to 1979. This transmission was a 3-speed automatic that was available in both rear-wheel drive and front-wheel drive cars. The FMX transmission had a cast iron case and used a torque converter to connect the engine to the transmission.

This type of transmission is no longer used in Ford vehicles, but was replaced by the AOD transmission in 1980.

How Many Quarts of Transmission Fluid Does an FMX Transmission Take?

An FMX transmission typically holds between 12 and 14 quarts of fluid. This will vary depending on the model and make of your vehicle. You should always consult your owner’s manual to determine the specific amount of fluid required for your particular car.

Overfilling the transmission can cause serious damage, so it is important to be precise when adding fluid.

Conclusion

The main problem with this transmission is that it is not very durable. Many people have reported problems with the gears slipping, especially when going up hills.

The other major problem with this transmission is that it is very difficult to find parts for it. This can make repairing or rebuilding the transmission a very costly proposition.
