What's wrong?
The transmission grade brake on the 2015-2016 Fccc S2G is part of the powertrain, the system that sends engine power through the transmission to the wheels. On trucks with the 8.0L propane engine and Allison transmission, the grade brake is supposed to help slow the truck on downhill grades by commanding transmission downshifts instead of relying only on the service brakes.
On affected trucks, the grade brake disable switch does not turn the feature off when the driver presses it. DTNA traced the problem to an incompatibility in the ordered options, which leaves the grade brake engaged when the driver expects it to disengage. In icy or otherwise slippery conditions, that unwanted grade-brake action can trigger aggressive downshifting and cause a loss of traction.
There is no warning sign before failure. The driver presses the disable switch, but the truck still acts as if the grade brake is active.

What's the safety risk?
If the transmission grade brake stays engaged without the operator knowing it, the vehicle faces higher crash risk in low-traction conditions. Drive with extra care on slick roads and schedule the programming update promptly. Repair is free at any franchised Fccc dealer.
What should I do?
- Check your VIN to confirm your 2015-2016 Fccc S2G is included in this recall.
- Contact a franchised Fccc dealer to schedule the free software update that fixes the transmission grade brake disable-switch problem.
- Bring the recall notice if Fccc mailed one. If not, reference recall number 17V215 when you call.
- Avoid icy or slippery roads until the programming update is complete.
- Call Fccc customer service at 1-800-547-0712 with questions and reference Fccc recall FL-734.
What happens at the repair
At the dealer, an Fccc technician updates the vehicle programming that controls the transmission grade brake behavior. The update is intended to make the disable switch work as designed, so the grade brake does not stay active after the driver turns it off. The recall repair is free at authorized service facilities, with parts and labor covered under campaign 17V215.
