What kind of transmission does a Sierra 1500 have?
HI I bought my old company work truck about 6 months ago. It is a 2007.5 sierra 1500 extended cab with the 4.8 with auto trans. About 2 weeks ago I was getting on the freeway and it shifted from 1st then 2nd and then like it was in neutral.
Which is GM rear wheel drive transmission is the best?
It has been considered to be the best rendition of the finest overdrive automatic transmission ever produced. The 4L60-E is found in nearly every GM rear-wheel-drive application, including the C/K Truck, Sonoma, Jimmy, Tahoe, Yukon, Astro, Safari, Suburban, Bravada, Firebird, Camaro and Corvette
What happens when you put a GMC Sierra 1500 in drive?
I then changed the speed pickup on the transfer case, which did not help the speedometer. Now the truck will shift 1-2 manually, but when you put it in drive, it free wheels: nothing at all; no drag or anything. The computer just checks code 12. If you put it in drive, it stays in low.
Can a 3rd and 4th gears work on a GMC Sierra?
3rd & 4th gears would work sometimes, other times not. You checked all the wiring, pins and plugs and all look good. You put in a used vacuum control module and that didn’t change anything.

Why does my transmission not shift into 3rd or 4th?
P0121 is a throttle position sensor and the P0171 ha to do with the engine running too lean Any luck getting this addressed since your last post, Ozzie? Not yet, I think I will try replacing the solenoids in the transmission first. If that doesn’t work then I guess its time to have it rebuilt.
