Not really much of an auto fan in general; I personally like that extra pedal to the left. The 4L60E (and 700R4, for that matter) is pretty well known as a problematic/weak/short-lived transmission (at least in stock form). I might stick an old TH400 in something if I just want to act stupid (drag racing), but other than that the autos don't really do much for me. |
I assumed from your 6.0 thread post you bought it because of the deal and it was a 6.0. (not MPG capable) [was was the title 'what a deal!']
When I read
(Suburban vs. Impala (or similar) fuel economy?) I assume were discussing fuel economy as most of these cars don't have original motors.
Aero to aero.... same motor and rear gear set... impala wins 10 out of 10 times
By your last post I'm assuming your talking suburban vs. impala with OEM motors, trans and rear gears then.
If that is the case.... suburban will have some input and probably impala will be the wrong forum or only a response or two from actual impala owners.
It'll be a wash as the impala has twice the weight.. twice the aero.. truck is half as heavy but just a boat sail.
Maybe consider a diesel swap otherwise if your chasing real MPG. (cummins 4BT, 4BD1/2T isuzu etc. if you want 30+ mpg)
Good luck to your endeavors of a 4 door impala vs. suburban. Hopefully you figure out what you really want it for... as impala is passengers and a big/short trunk... burb is tall cargo that can carry passengers on occasion.[a YOU decision]
