You can still shift an "automatic" transmission manually... There's just no clutch pedal needed...
I love to shift manually, both up and down, and I usually shift for myself (when in my Chevelle)... Never been a problem manual shifting my automatics. I have never broke or burned one up by manually shifting, and I am hard on cars (or used to be)....
I prefer the automatic in mine, although I wish it had OverDrive... Its kind of like the best of both worlds: shift when I want but can do it automatically when I am tired and lazy. :thumbsup:
My driveway is also short and relatively steep with a shallow stall where the Chevelle goes. I'd hate to be burning up the clutch trying to get it into the garage every time I drove it...
The only drawback I see, is I am stuck with a limited amount of stall speed...
Of course, my '70 came with an automatic already, and it has enough power to scare people (it will smoke the tires from a 20+ MPH roll).
After the 5-speed in my convertible, I was tired of shifting (mainly tired of the clutch pedal)... Also harder to launch (IMO), and much harsher on parts (dropped a few driveshafts, etc over the years)...
My other Chevelle is a factory 4-speed (not running)...
