6.7 Powerstroke Torque Converter Problems

A torque converter is a device that translates rotational motion from the engine into linear motion. The torque converter is attached to the engine and has a large spinning cone that moves fluid from one side of the device to another. The torque converter is usually located between the engine and the transmission for power transfer.

The unit takes some of the motor’s energy and uses it to spin a turbine, which in turn spins an air pump that pressurizes oil and sends it back to the motor. The pressure created by this pumping action provides resistance against slippage between engine and transmission, so less wear on both components and fuel economy improves.

One of the most common 6.7L Ford Powerstroke torque converter problems is the torque converter gets unlocked in the 5th gear. Other problems can include the horrible noise from the engine’s transmission area. Let’s get to know others’ problems as well.

In the below guide, you will find out the 6.7 Powerstroke torque converter issue, their reasons, and solutions in detail.

The Torque Converter Gets Unlocked In The 5th Gear

Some owners of the 2011 Ford F-450 pickup truck said that when they went to cross pass another truck and their truck shifted into 5th gear, the torque converter got unlocked. They have let off the pedal and shifted their truck into 6th gear, but the torque converter would not lock back up.

Also, they have said that they are running the H&S transmission tune.

So, it happens for a tuning issue. In such cases, you have to reload the H&S transmission tune to solve this issue.

Noise Coming From The Bell Housing Area On The Transmission

We have found out that the 2012 Ford F-250 truck can sometimes make unexpected noise, which comes from the bell housing area on the truck’s transmission. This issue mainly happens after changing the oil. It occurs due to the loose bolts of the torque converter. You have to tighten the bolts of the torque converter to fix this 6.7L Ford Powerstroke torque converter problem.

Other causes of noise from the bell housing area on the transmission include a loose or damaged drive shaft, worn-out bearings, or an imbalanced engine. If you’re hearing this noise, it’s essential to have your truck checked out by a qualified mechanic to diagnose it.

Otherwise, a bad torque converter can eventually lead to transmission failure. Therefore, it’s crucial to take action as soon as you hear this noise to avoid further damage to your truck.

Torque Converter Nuts Won’t Tighten Up

Sometimes, after changing your vehicle’s rear plate seal, you may be unable to tighten the nuts for the torque converter. From the 6 nuts of the torque converter, you may not be able to tighten 4 nuts.

This problem happens because the torque converter nuts were stripped while removing them. To solve this issue, you have to slide the transmission back and pry between the torque converter and flywheel while loosening the nuts. If the problem is still not fixed, you have to replace the torque converter nuts.

Horrible Noise From The Engine’s Transmission Area

Many people have complained that their 2013 Ford F-250 trucks make a horrible rattle or banging noise from the engine’s transmission area. It happens after they have driven their trucks for one hour. This problem occurs for a faulty torque converter. You are required to replace the torque converter to solve this issue.

Another common cause of a 6.7 Powerstroke torque converter issue is with the clutch. If the clutch is not working as it should, it can cause the engine to make a loud noise.

If you think that your engine is making a horrible noise from the transmission area, you should not avoid it. Several different things can cause this problem, and a mechanic will be able to diagnose the problem and fix it. Mainly a faulty torque converter can cause a horrible noise from the engine transmission area.
