Yes well it may be a heavy vehicle, but after logging approximately one million klms in various work vehicles, some equipped with automatic transmissions, this is first one I have ever driven that will not hold the speed on hill, given that the approach speed to the hill was appropriate. My last vehicle, a Ford 450, gas,weighing in at 15,000 pounds and automatic equipped went to auction at 250,000 kms with its original brakes. For instance a hill I used everyday at Drumheller Alberta on a curvey road was posted at 70km/hr. If I approached that hill at 70km/hr the engine would hold that speed all the way with the transmission in 2nd gear. Didn't have to ride the brakes all the way down, as with the Journey.
