wide ratio vs. close ratio 10-speed manual tranny. - Diesel Forum

**SmokeyWren** · 11-25-2008, 10:34 PM

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.

With some of the Roadrangers (which is what he has) you could dis-assemble the trans and "X" four gears, main shaft versus countershaft, and you'd end up with different ratios in the top couple gears. Without a shop manual stating what number of teeth gears give you what ratio, I doubt if anyone here, including my self, can be of much help.
