So you are saying 2nd prime/3rd gear is completely safe and not a "weak link" in the tranny under full load, as another member put it? I know we're getting off topic from original post but I'd like to know. If it is safe, I'm assuming correct use on the strip would be to just set manual gear limiter to "3" and increase it once it has already shifted to 3rd so that the tranny can up shift once I let off. Also...doesn't tow mode use 3rd? If so, why not just do that instead of the manual route? As you can tell I'm still learning my truck so thanks for any accurate clarification it is appreciated.
