What's wrong?
The transmission oil cooler on the 2014-2019 Freightliner Business Class M2 sits inside the radiator tank and pulls heat out of the transmission fluid as it circulates. A short hose carries that fluid from the transmission to the cooler, and a small retaining clip locks the hose onto the cooler fitting. The clip is what keeps the connection sealed under pressure and vibration.
On affected trucks built with Mahle-Behr radiators and Jiffy-Tite quick connect fittings, the retaining clip can fail. Once the clip lets go, the hose can disengage from the in-tank cooler and transmission fluid escapes at the connection. A loss of transmission fluid can lead to a slipping or unresponsive transmission and leaves slick fluid on the road behind the truck.
A leak is usually something a driver notices, but if it happens fast enough, fluid can be lost before the driver sees it and pulls over. Watch for red or brown fluid under the front of the truck, a burnt smell, or a transmission that shifts harshly.

What's the safety risk?
A sudden loss of transmission fluid can create a road hazard for other drivers and raise the risk of a crash. The leak is usually visible before it becomes severe, but a fast leak can happen before a driver notices and pulls over, so treat any fluid drip under the truck as a reason to stop driving and call the dealer. Repair is free at any franchised Freightliner dealer.
