Are you a BMW X5 owner experiencing shifting problems with your transmission? Don’t worry, you’re not alone. In this article, we’ll discuss a common transmission issue found in the BMW X5 E70 and share a simple and affordable solution to fix it. Many people end up selling their cars or replacing the entire transmission, unaware that there is a much cheaper and easier fix available. Read on to learn how you can save thousands of dollars by addressing this problem without even opening the transmission itself.

Symptoms of the Problem

One of the main symptoms of this transmission issue is difficulty shifting to drive or reverse, especially when the car is hot. You may find yourself having to go back and forth between drive and reverse multiple times to get the car to start moving. Additionally, you might need to apply excessive force on the pedal for the car to suddenly lurch forward. In some cases, a “transmission malfunction” warning may also appear on your dashboard. If you’ve been experiencing these symptoms, then you’re likely facing the same problem as many other BMW X5 owners.

Identifying the Faulty Component

The culprit behind these shifting problems is a plastic bridge located in the mechatronic module, which is responsible for controlling the transmission. Over time and with exposure to heat, this plastic bridge can crack and become bent, causing the shifting issues you’ve been experiencing. Luckily, replacing this plastic bridge is an easy and affordable solution.

The Fix: Replacing the Plastic Bridge

To fix this transmission issue, you’ll need to replace the plastic bridge. The good news is that this part is readily available and costs only around $40. Here’s a step-by-step guide on how to do it:

  1. Begin by draining the transmission oil and removing the transmission pan. This will give you access to the mechatronic module.
  2. Unscrew the mechatronic module from the transmission pan.
  3. On the left-hand side of the mechatronic module, you’ll find the plastic bridge, also known as the valve body adapter.
  4. Remove the old plastic bridge and replace it with the new one.
  5. Finally, reassemble the transmission pan, ensuring you have a new pan, filter, screws, gasket, and bridge.

Additional Plastic Components

While replacing the plastic bridge, you might also consider replacing other plastic components in the transmission if you wish, although it is not necessarily required. These additional parts may contribute to the overall health and longevity of your transmission.

The Cost-Saving Advantage

By replacing the plastic bridge yourself instead of opting for a costly transmission replacement, you can save a significant amount of money. Each time you undergo this repair, including the cost of the plastic bridge and labor, you can expect to pay around $580 Canadian dollars. Compared to the potential cost of a full transmission replacement, this is an incredibly affordable fix that can help you save your transmission and your car.


Dealing with transmission problems in your BMW X5 E70 can be frustrating and expensive. However, knowing the common issue and solution discussed in this article can save you thousands of dollars. Remember, by replacing the cracked and bent plastic bridge in the mechatronic module, you can fix the shifting issues and ensure smooth driving once again. Don’t let a seemingly major transmission problem discourage you from keeping your beloved BMW X5 on the road. Take advantage of this affordable fix and enjoy many more miles of driving pleasure.
