Ehhhh, I've stayed away from the Hondamatics after seeing all the early model problems people where having, but after seeing @basfnb
's 06 Rubicon get beat on for 10 years of hard use, I've kinda changed my mind on them.
The early Rubicons definitely had issues. Oil pumps or Hondamatics, depending on who you ask, but they would either go 10K miles without a hiccup or blow up with 500 miles of light riding on them.
05-14 Rubicons you hardly ever see transmission issues. In fact, I've never personally seen an 05-14 that had transmission issues. They DO have a lot of electrical crap on them and that could be a PITA to troubleshoot, but in the 10 years I've been around these things, they 05-up Rubicons have changed my mind. Basfnb's has been tough. Ridden hard, put up wet, and he's never had electrical or transmission problems. Just bearings and a top end cause he didn't maintain his air filter.
My father in law has an 06 with 14K on it. It's been abused, stolen and recovered, and is still ticking (it really does tick now, but still runs, drives, and doesn't smoke).
We have another guy we ride with who sank his 07 3-4 years ago. Flushed it out, still runs great to this day.
I got one a few months ago. It had electrical issues, so I put a used wiring harness on it and so far it's been a great machine. I really like the seamless power from the Hondamatic versus the clunky shifting in my wife's 420AT with the newer DCT style automatic transmission.
I guess automatics have always seemed like voodoo magic to me, and the Hondamatic is no different in that regard, but after @harig
posting up on how they work, what could possibly go wrong, and just seeing some of them hold up to a lot of abuse over a long period of time, I've become a fan of the 05-14 Rubicons.
