"My truck will downshift to second gear and fly up to around 5 grand on hills occasionally. But it just stays there very briefly, gains speed, and upshifts."
Unacceptable for a heavy duty towing vehicle gas, diesel or otherwise.....IMHO. If the engine can't pull it's own in the 3000-4000rpm's range with heavy loads on steep grades it's not up to the task. Not being able to keep it from doing that 3-4 gear downshift deal doesn't cut it for me, when I select the "manual" mode the ECM shouldn't go ahead and seek lower gears then "buzz" the engine in my $60,000 truck to and past 5000rpms. Doesn't matter how well it's made or designed that kind of RPM isn't cutting it for me and it can't be good for the engine in the big scheme of things.....IMHO
"The surging and the transmission lugging and then all of a sudden downshifting with the grace of a buffalo in a china shop is annoying."
Excellent description and the dealership thought that deal was perfectly fine. I tell everyone I know about it even if some folks on these Forums get their panties all wadded up about getting a little off-topic. The general public needs to know the good and bad points of these vehicles before going out and paying more for one than I paid for my last house!.......FWIW.......Cliff
