[100% Fixed] 6.4 Powerstroke Transmission Problems & Costs!

Last Updated on February 27, 2023 by Robert Wilson

The 6.4 Powerstroke transmission is a common problem for these trucks. The main issues are with the torque converter, which can cause the truck to stall or lurch forward when shifting gears. The good news is that there are some aftermarket options that can fix these problems.

If you own a Ford 6.4 Powerstroke, you may have experienced some transmission problems. Here’s what you need to know about the most common issues and how to fix them.

The first thing to know is that there are two different types of transmissions in the 6.4 Powerstroke: the TorqShift and the 5R110W.

The TorqShift is a five-speed automatic, while the 5R110W is a six-speed automatic. Both transmissions are built by Ford, but they have different designs and internals. The most common problem with the TorqShift transmission is that it can slip out of gear when under load.

This usually happens when towing or hauling heavy loads. To fix this issue, you’ll need to have your transmission serviced by a qualified technician who can replace the worn parts. The 5R110W transmission is also known for having shifting problems, but these are typically caused by low fluid levels or dirty fluid.

If your transmission isn’t shifting properly, make sure to check the fluid level first and then have the system flushed and refilled if necessary.

What Transmission is in a 6.4 Powerstroke?

The 6.4 Powerstroke is equipped with a six-speed automatic transmission. This transmission is designed to handle the high torque output of the 6.4 Powerstroke engine. It features a wide ratio gear spread that allows the engine to operate at its peak performance levels.

The transmission also has a tow/haul mode that can be activated when hauling or towing heavy loads.

Is There a Fix for the 6.4 Powerstroke?

The 6.4 Powerstroke engine was introduced in 2008 as a replacement for the aging 6.0 Powerstroke. The 6.4L brought many improvements over its predecessor, including increased power and torque, improved fuel economy, and a more reliable design. However, the 6.4L also had its share of problems, most notably with the turbochargers and EGR system.

While there is no one “fix” for all of these issues, there are several aftermarket products available that can help improve reliability and performance. One common issue with the 6.4L Powerstroke is turbocharger failure. This can be caused by a number of factors, including poor quality oil, excessive soot buildup, or faulty exhaust gas recirculation (EGR) valves.

Many times, simply replacing the oil with a high-quality synthetic will help extend the life of the turbochargers. If you are having persistent problems with your turbochargers, however, it may be necessary to replace them with an aftermarket unit designed specifically for the 6.4L Powerstroke. Another common issue on the 6.4L Powerstroke is failure of the EGR system.

The EGR system helps reduce emissions by recirculating some of the exhaust gases back into the engine cylinders where they can be burned again. Over time, however, deposits can build up on the EGR valves and cause them to stick open or closed – both of which can lead to engine damage or decreased performance .

How Long Will a 6.4 Power Stroke Last?

The 6.4L Power Stroke is a turbocharged diesel V8 engine that was introduced in 2008. It replaced the previous 5.4L Triton V8 and was used in Ford Super Duty trucks until 2010, when it was replaced by the 6.7L Power Stroke. The 6.4L Power Stroke is available in two versions: a standard version with 350 horsepower and 650 lb-ft of torque, and a high-output version with 385 horsepower and 850 lb-ft of torque.

While the exact lifespan of a 6.4L Power Stroke will vary depending on how it is used and maintained, most engines will last for at least 200,000 miles if properly cared for. With proper maintenance, some engines may even last for 300,000 miles or more. To help ensure your 6.4L Power Stroke lasts as long as possible, be sure to keep up with all scheduled maintenance appointments and use good quality fuel and oil filters.

If you notice any unusual noises or performance issues, have the engine checked out by a qualified mechanic as soon as possible to prevent further damage.

Is the 6.4 Power Stroke Reliable?

The short answer is yes, the 6.4L Power Stroke is a reliable engine. However, like any engine, it has its share of problems that can crop up. In this article, we’ll take a look at some of the most common issues with the 6.4L Power Stroke and what you can do to avoid or fix them.

One of the most common issues with the 6.4L Power Stroke is oil leaks. The good news is that there are several aftermarket companies that make replacement gaskets and seals for this engine that are much more reliable than the factory parts. If you’re noticing an oil leak, it’s best to get it fixed as soon as possible to avoid any further damage to your engine.

Another common issue with the 6.4L Power Stroke is turbo failure. This can be caused by a number of things, but one of the most common causes is lack of proper maintenance on the turbocharger itself. It’s important to clean and inspect your turbocharger regularly to make sure it’s in good working order and to prevent potential failures down the road.

If you’re looking for a reliable and powerful diesel engine, the 6.4L Power Stroke should definitely be at the top of your list! Just remember to keep up with regular maintenance and watch out for common issues like oil leaks and turbo failure and you’ll be sure to have a long-lasting and trouble-free engine!

6.7 Powerstroke Transmission Problems

If you’re the owner of a Ford 6.7 Powerstroke diesel truck, you may be all too familiar with transmission problems. These trucks are known for having issues with their transmissions, and it’s a problem that seems to be getting worse, not better. In fact, there have been so many reports of transmission problems with these trucks that Ford has issued a recall on them.

There are several different symptoms that can indicate a problem with the transmission in your 6.7 Powerstroke truck. If you notice any of these, it’s important to get your truck checked out by a qualified mechanic as soon as possible: -Harsh or erratic shifting

-Delayed engagement when shifting into gear -Check engine light is on -Grinding or shaking when shifting gears

-Transmission fluid leaks If you’re experiencing any of these problems, don’t delay in taking your truck to a mechanic. Ignoring the problem will only make it worse and could eventually lead to complete transmission failure.

And if your transmission does fail, it will likely need to be completely replaced – which is an expensive repair. So if you own a 6.7 Powerstroke diesel truck, keep an eye out for transmission problems and don’t hesitate to get your truck serviced if you notice anything out of the ordinary.


If you’re the owner of a 6.4 Powerstroke, chances are you’ve had your share of transmission problems. Whether it’s an automatic or manual transmission, the 6.4 is notorious for having issues. In this blog post, we’ll take a look at some of the most common problems and what you can do to fix them.

One of the most common transmission problems on the 6.4 is slipping gears. This can be caused by a variety of things, but most often it’s due to low fluid levels or contamination. If your transmission is slipping gears, make sure to check the fluid level and condition first.

If it’s low, add more until it reaches the proper level. If it’s dirty, flush it out and replace with clean fluid. Another common problem is hard shifting.

This can be caused by several things as well, but usually it comes down to either low fluid levels or worn clutch plates/bands. Again, checking and topping off fluids is always a good place to start troubleshooting this issue.
