Hope this helps. You can find more information the Work Horse web site. www.workhorse.com
The driver activates TGB through an illuminated dashboard switch. Then he or she engages the feature by depressing the brake pedal and releasing. The transmission automatically downshifts a gear and starts to control the motor home's speed.
So on a steep decline the driver just needs to step on the brakes to let his transmission automatically provide a smooth, safe ride downhill. This avoids unnecessary wear on the brakes while providing a reassuring sense of control to the driver. No stress, no sweat: TGB does the work.

Adding onto Mandy's comments, I leave the Grade Brake activated all the time, that way when the transmission senses a downhill push, the transmission automatically downshifts, even on gently sloping down slopes.

It's merely engine braking, the same as you can do yourself by downshifting the transmission and letting engine back-pressure slow you down. Grade Brake just makes it automatic.

workhorse added the TGB dash switch in the 2005 models.

The Grade Brake is not activated by sensing a "downhill push". It is activated, with the switch in the ON position, by touching the brake pedal. The transmission will then down shift a gear as long as the speed is with in the safe range for that gear.
No Grade Brake on your model?? You can do the same by downshifting the transmission with the shift lever/pad.

Tom I beg to differ, but my unit will not downshift on level ground when I hit the brake gently.
