The 6-speed was available in the 2000 model year with the standard output motor. I have one with 102,000+ miles. Of course it is not standard now..... added EZ and DDII's awhile back. I have a 2004. 5 on order and I truely hope I do regret the upgrade. The biggest problem with mine now is that I really need a 3500 chassis and the brakes on the 2000 suck bigtime. The 2004. 5 had mucho mucho better brakes.
