Here is more proof for the pudding: 2008 Trailblazer 5.3V8 4l60 trans, 3.42 rear. The same setup in run of the mill half ton pickups. It could not do 60MPH downhill 7% grade. In fact it could not stay 4th gear going downhill. 300HP and commuting rear ends are meant for grocery stores and daycare jaunts!
Thats more responses that dont make any sense what so ever..
So you could not do 60 mph down hill? Why? Hmmm tow haul mode on? Were you towing something? Of course its going to slow you down...
Why would a 3 42 rear and a 3 73 rear differ down hill? My commuting rear will do the same as a 3 73.. no difference but 200 rpm or so...
If you cant lay the facts to your response and be more clear please do not respond at all...
Duh... going down hill 7% you want the truck to hold back. so from your post the truck did what it was supposed to do...
Another uneducated post IMO... All my opinion of course.
