Infiniti QX56 Transmission Problems/Repair Costs/Fluid Change

Last Updated on September 25, 2023 by Robert Wilson

The Infiniti QX56 is a full-size SUV that was introduced in 2004. It is based on the Nissan Armada and shares many mechanical components with it. The QX56 was Infiniti’s first SUV and was originally offered only with a 5.6 L V8 engine and 4-speed automatic transmission.

In 2007, a new 7-speed automatic transmission became available. Both engines are mated to an all-wheel drive system. Since its introduction, the QX56 has been plagued by transmission problems.

The most common problem is premature wear of the transmission’s internal components, resulting in poor shifting quality and reduced durability. Many owners have also reported issues with the transmission “hunting” for gears, especially when cold or under load. These problems can lead to expensive repairs, as well as decreased resale value.

If you’re the owner of an Infiniti QX56, you may have experienced some transmission problems. Some common issues include the transmission slipping or jerking, and the vehicle hesitating when accelerating. These problems can be caused by a variety of things, including low fluid levels, dirty fluid, or a faulty sensor.

If you’re experiencing any of these issues, it’s important to take your QX56 to a qualified mechanic for diagnosis and repair. Trying to fix the problem yourself could make it worse, so it’s best to leave it to the professionals.

Infiniti Qx56 Transmission Replacement Cost

If your Infiniti QX56 is in need of a transmission replacement, the cost will vary depending on a few factors. The first factor is whether you replace the transmission yourself or have it done by a professional. Replacing the transmission yourself will obviously be much cheaper, but if you don’t have the time or knowledge to do it, then it’s best to leave it to the professionals.

The second factor that will affect the cost of replacing your QX56’s transmission is the type of transmission you need. There are two main types of transmissions – automatic and manual. Automatic transmissions are much more expensive than manual transmissions, so if you have an automatic, expect to pay more for the replacement.

Finally, the last factor that will impact the cost of your QX56 transmission replacement is where you get your parts from. If you buy aftermarket parts, they will be much cheaper than OEM parts from Infiniti. However, aftermarket parts may not always be as high quality as OEM parts, so make sure you do your research before buying anything.

All in all, expect to pay anywhere from $2,000-$4,000 for a complete QX56 transmission replacement – depending on all of the factors mentioned above.


If you’re having Infiniti Qx56 transmission problems, you’re not alone. Many drivers have reported issues with their transmissions, ranging from minor problems to complete failures. While Infiniti has issued a recall for some models, many drivers are still experiencing problems.
