Hello lebloom
I have a problem with transmission and you are not alone here. Every Honda dealer refuses to see the problem but problem persists. It shows worst in winter time. When I drive in stop and go traffic with speed 0-30 mph ten of 20 times HAH chatters on acceleration resulting in retarded acceleration and sometimes noticeable slow shifting gears. Another feature is a little jerks in steady highway driving when I just a bit move my foot on a throttle sometimes even without foot move. I bought 2007 HAH brand new and it was a fine car first 10k or 4 month. But above mentioned problem started and progressed afterwards. It is resulted in FE drop (about 5%), I'm getting about 31 mpg on my average commute in a summer and 27 mpg in a winter. 80% - highway. I regret that I bought a car w/o NAVY and now can't monitor my instant FE. I think to buy some data logger or inexpensive OBD-II scanner for my car. Any recommendations? I'm not a spirited driver but rather light footer. I keep my tire pressire 33 psi because I think about safety rather than FE.
