My name is ***** ***** I will assist you.

Scan the truck to see what code you have. The F is a failure of either the clutch or the shifter in your transmission. Question is which one.

Some of the Eaton transmission codes can be reset by cycling the key 5 or 8 times. You can try that so you can get to a shop as needed. Not all will work if the parameter is turned on to not allow it. Most Macks allow it though.

I just recently got brakes done. And it started with the issue. I will get the truck scanned though

What did scan show?

Brakes wouldn't cause. F on transmission.
