Freightliner Automatic Transmission Stuck in Neutral
Being stuck in neutral is different from being stuck in gear because the truck won’t move at all. Common fixes include:
Resetting the Transmission: As mentioned earlier, this can sometimes resolve the issue.
Checking the Linkage: The linkage might be loose or damaged.
Choosing the Right Transmission Fluid
The right transmission fluid is crucial for the smooth operation of your Freightliner’s transmission. Types of transmission fluids include:

Freightliner Cascadia Automatic Transmission Stuck in Gear
If you have a Freightliner Cascadia with an automatic transmission, you may find that it’s stuck in gear. This can be a real problem, as it means your truck won’t be able to move. There are a few things that can cause this to happen, and fortunately, there are also a few solutions.
One reason your transmission may be stuck is that the shift solenoid has failed. The shift solenoid is responsible for telling the transmission when to shift gears. If it’s not working properly, the transmission may get stuck in one gear and not be able to move.
Another possibility is that the torque converter is not working correctly. The torque converter is what allows the engine to continue running while the truck is stopped. If it’s not working properly, the engine will stall and the truck won’t be able to move.
Fortunately, there are a few things you can do to try and fix this problem. First, check the fluid level in the transmission and make sure it’s full. If it’s low, topping off the fluid may help solve the problem.
Second, if you have access to a scanner tool, you can try checking for any error codes that might be stored in the system. These codes can help point you in the right direction for fixing the problem.
If you don’t have a scanner tool, consider the FCAR F802 Heavy Duty Truck Scanner. It can read and clear fault codes, perform DPF regeneration, and reset oil service lights, which may be helpful in diagnosing and fixing the issue with the stuck transmission gear.
