3/4 Ton Suburban Transmission.
This is a fuzzy DISCUSSION post. After getting a new Chevrolet 1500 6-cyl truck for work vs. our Trailer vehicle (2011 3/4 Ton Suburban)- the Suburban seems to perform awful- nasty shifting habits and crummy mileage.
I know it's an apples to oranges comparison, but with a light utility trailer (~3000 lb), the 1500 actually pulls nicer AND gets better mileage than the Suburban pulling the same trailer.
I'd almost swear that it all comes down to how the computer is programmed on the transmissions....The 6 cyl usually is running at a lower RPM (yes, it drops down for hill climbs, but the Suburban is MUCH WORSE- seems like it doesn't like to pull and really likes to be running 3000 RPM- with the lighter trailer!).
Now- for the camper (Old 7000 lb, 27 ft TT), The 1500 seems to have very inadequate springs and the six might come up a little short on power AND would very likely get crummy mileage. (Never actually hooked it up, but it takes very little to squat it down)
Still, I feel (yeah feel) that the Suburban should perform better and upshift more when on level or slight downgrades (It spends lots of time in third and fourth gear....I get it that maybe 6th isn't called for but sometimes it almost refuses to go into 5th....3500 RPM on a slight downgrade!
I guess the real question here is if anyone can comment on a newer 3/4 ton Suburban vs. an older one and if the shift patterns and gas mileage have improved markedly?
(PS- oh for a good ole four on the floor :-) )
