Xe18 Posted April 24 Share Posted April 24 Lately my truck has issues with the trans didn’t disengage or cut off when coming up to a stops when the brakes were applied. This issue is happened intermittently. The trans will down shift to 4 or 1 gear but it keeps pulling after that until a hard press down on the brake pedal then the trans cut off / disengage and no more pull… Please help!

The Heinz Posted April 24 Share Posted April 24 Could be brake demand switches by the brake pedal, had several instances where they would fail and cause similar symptoms. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76595-cxu-2016-mdrive-transmission/#findComment-594947 Share on other sites More sharing options...

The Heinz Posted April 28 Share Posted April 28 I forget how many there are under there, it depends on the year too. There were usually two part numbers, one ending in a 116, the other 118, that were for different PSI's. My helpfulness kind of comes to an end there...
