2009 GMC Sierra 1500 SLE 4dr Crew Cab 5.8 ft. SB (4.8L 8cyl 4A)
Ok guys, this is my update. I sold my 09 gmc after owning it for 8 months. When I did, it had 17 service records! The clunk and hard shift you have on the transmission was due to a part installed backwards! I had the sounds of rocks in the rolling wheels at slow speeds, and sloshing gasoline sounds when pulling out of the driveway. I was at the dealership so many times I got to know the staff! For appearance sake, the truck was gorgeous, but mechanically, it grew very old very fast. I spoke to a friend who bought a silverado, and he had the same transmission problems. So let's hope they've fixed it by now! I'm buying a Ford next! I didn't even look at them before I bought my gmc. Big mistake! Bad bad!
Make sure you build them right! If a Truck costs nearly $40k, it should be ROCK SOLID... here I come FORD!
