I was and still am a little in awe? of the I shift. I stated in a previous post, I had changed the air filter, since when I have found the I shift a little more amenable, especially changing between 1st and 2nd.
Having driven conventional automatics for over 10 yrs, I am trying to get into the habit of foot off footbrake and handbrake on when stopped at lights etc, leaving it in gear. As far as I can make out, reading the info in the manual etc, providing the engine is not running above tickover, the clutch is disengaged. I like most, wonder about the 'clutch release bearing but conventional stick shift cars seem to cope with people sitting with their foot on the clutch, in gear at lights etc.
I am mindful, that when sitting still for any length of time, an auto box should be put into N or P as the torque converter will overheat. The I shift doesn't have a torque converter, so presumably the clever little men at Honda have set the system up, so that when stopped, with the engine on tickover, the clutch is disengaged. SO back to the clutch release bearing, I suppose you pays yer money and takes your chance.
