No need to get your panties in a twist. Re-read your own post, it says if you use cruise and cannot stay at 65 or get into the hills then it will constantly be shifting into/out of 6th. The only reason for that would be cruise being more aggressive when trying to get back to the set speed, as I said in my post. The act of using cruise itself doesn't change shift points.I did not say Cruise or Tow/Haul locks out 6th gear. I said that if you cannot stay above above 65 mph, your transmission is constantly in/out of 6th gear, causing the gas mileage to go to S...
My trailer tires are rated at 65 mph Max. and it’s hard for me to stay right on that without variance with road conditions. That is why I have chose to use M5. Getting good mileage. My choice, not yours. Thanks.
I believe that what you are trying to argue about is what I said in my prior post, read it again. Let the V6 guys help the V6 guys.
Now, go and read the last sentence in your post, it says you can use Tow/Haul or you don't have to if you use M5, which implies they do some of the same things. There have been previous posts about Tow/Haul locking out 6th gear and your comment implies it does, at least the way I read it. However, it doesn't lock out 6th..
When I tow and use cruise control my MPG doesn't change.
When I tow and use cruise control it never shifts into 6th gear due to engine load with the travel trailer.
When I enable Tow/Haul it doesn't lock out 6th gear. It's not the same as using M5.
You want me to not comment on gas threads then by all means you can stay out of the diesel threads and let the diesel owners help diesel owners. Otherwise, sorry. Too bad.
