i have found that once on the freeway, i 'shift' into 6th gear...and leave it there until i exit the freeway. doing this has increased my mileage a little....the car usually hasn't had any problems pulling hills, albeit not the same type of hills in other parts of the country, but, if it really begins to struggle...it will downshift on it's own.I like it as well. Never any clunky shifts. Seems to make the car pretty responsive and peppy given the engine size. I would say my only complaint if you would even call it that is the programming to plant it firmly in 6th gear and not budge unless you really punch it.
Like "They" always say. "It isn't the size of your engine, but how you use your shifter."
I am interpreting "lousy" as upshifting too soon or the wrong shift points for a given speed? The GM transmission is adaptive, so it's not easy to judge them by a single drive in a single car, especially if it's a rental car that's been beaten ruthlessly.u guys wanna feel a lousy 6 speed tranny ? check out the latest buick lacrosse tranny...horrible. the koreans out engineered them by a long shot.
