I have been wondering about the transmission gearing. In one of the Four Wheeler of the year competitions I read a while back, the Frontier actually finished near the bottom in their crawl test. They just put all the trucks in first gear and idled toward the finish line, and the last one to the finish line was the winner. It is kind of an unscientific test. However, I thought it was strange that the Frontier would do poorly with the low ring and pinion gearing we all have. I know our transfer case gearing is tall. I agree that transfer case gears would probably be a better choice than R & P gears, unless your highway performance is poor. Also, I think I read that the transfer case gear installation is a do it yourself job.
