0 alex g Posted May 27, 2021 Share Posted May 27, 2021 I think you'll be fine pulling them Hills you'd better take it easy coming down the other side. Where are you pulling 15% grades?

0 mrsmackpaul Posted May 28, 2021 Share Posted May 28, 2021 It will climb fine, as said, coming down will be more interesting A nice low gear, usually a gear lower than you climbed is my rule of thumb, most people say the same gear but I'm a pussy lol Paul Quote Link to comment https://www.bigmacktrucks.com/topic/66774-mack-e7-400-8ll-trans-with-563-ratio/#findComment-474434 Share on other sites More sharing options...

0 Steve L Posted May 29, 2021 Share Posted May 29, 2021 How very true Hayseed I lost a truck over the range going down to Balina from Adelaide early 70s in a Ford D1000 185 Cummins overloaded to the crapper ( as we did back then ) the red reflections on the bitumen from the hot brake drums were brighter than the side lights on the trailer. It stayed upright tho and I’m here to tell the story. So I have been a pussy going down hills ever since. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/66774-mack-e7-400-8ll-trans-with-563-ratio/#findComment-474484 Share on other sites More sharing options...
