Do I wait for the 5 speed?

I've read about some of the horror stories but my experience with the passon 5 spd is I love it. No issues with it jumping out of gear. Initially what I did experience was a clunking when shifting from 2nd to 3rd. Clunk would disappear after a 15 to 20 minutes of operation. This seemed to occur in cooler weather. After talking to Jammie and trying to figure out what was occurring, this included removing Trans and taking back for inspection. Nothing apparently seemed to be wrong. Same result, clunky at times when cold. Shortly after this they came up with a different type of gear oil and it cured the issue. Can't recall the brand or type at the moment but I have it documented. As for the price, yes it's expensive but so is everything else today and tomorrow. Was a bit of a pain in the beginning but I'm happy and glad I went with the 5spd. Running 3:55 rear gears and cruises effortlessly at 75 mph and up. I drive the duster 7 hrs to Carlisle and other long distance cruises. Hopefully if you purchase one you will have positive experience also. Good luck with your decision.
