Awhile back we came up with the question what this 3000rpm thing actually mend, I posed this question on another forum and what came out is that in 4th and 5 th gear you don't want to go over 3000 rpm. For me it works out to simply keep it under about 12 mph in low range. Feel better about that and yes I absolutely love that screaming little box, makes my little Jeep go places, that I otherwise would be burning the clutch on and helps a ton on control on big rocks. Where other people with bigger tires struggle and work hard my little put put walks right over it got to love it
