MackManDan Posted February 13, 2019 Share Posted February 13, 2019 Hey everyone, I have a 2012 CXU613 with an MP8 and M-Drive Transmission. 2 days ago I was docking and when I was pulling up and braking, the transmission felt like it wasn't disengaging. After I docked, I went to drop the trailer, but I couldn't get the transmission into gear. As I was pressing the brake pedal, the warning to depress the brakes before changing the selector switch kept coming up. I was able to go into Limp Mode and drop the trailer, but needed to get towed because it wouldn't go into regular Drive. I used the Tech Tool and a brake switch fault is coming up active. I haven't been able to find the service information on Mack's website and the Tech Tool isn't giving me any information on where the brake switch is either. Does anyone know where it is? Any insight would be appreciated. Thanks. Quote Link to comment Share on other sites More sharing options...
