I just purchased a new 2017 Ridgeline RTL and hear a clunk in the transmission, sounds like i ran over a garbage can, on upshifts driving around town. To me it is a concerning sound. Of course the response of the service department is , don't worry its under warranty. Mechanic went on test drive with me and agreed it doesn't sound correct but, of course no one wants it admit that there might be a transmission concern. Having regrets I didn't purchase a Chevy or Toyota.
