When coming down from our local ski-hill on a long 10-15% grade (just a couple of people and no other load) I have tried using the tow-haul button to engage engine braking. Speed coming down would be around 80 kmh = 50 mph
It engages promptly, but then as I go down, it downshifts another gear, fairly screams, and actually slows the truck down to around 50k = 30mph.
Is there a way to get the benefit of some engine braking without it downshifting some more? Is there a way to get it to hold 4th instead of going to 3rd?
Also, when I want to speed up a bit again, even if I release the tow-haul mode, I have to step on it quite vigorously to get it to up-shift again. Is there a way to get it to release more easily??
I have also noticed that sometimes on a fairly shallow down-grade at 90-100 kmh = 60mph even WITHOUT engaging tow-haul a light tap or two on the brakes will cause a downshift, and sometimes it won't.
Is there any way to make that happen predictably on command??
