We have a new member who apparently uses English as a second language. I can't really understand his question, but it sounds like maybe he's asking about a 10-speed manual tranny with a wide ratio and top gear being direct drive, vs a close ratio where the top gear is overdrive. I moved the thread to the General Diesel forum, so if you don't usually monitor that forum but know anything about real-truck trannies, please see if you can help him.
