Best of luck to you, it really isn't that hard to make the ABS work right. As for the previous owner, it never ceases to amaze me how much time and effort someone will put into fixing something the wrong way.
2007 4L80E 4 speed automatic was replaced by 6L90 6 speed automatic. 2007 6.6L also got VVT. New chassis, front axle and suspension in 2011. I think 2011 and newer is better if it's in your price range.
C/K Man replied to Carolina's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)The 8L+ engine rumor started about a year ago, was widely reported but have not heard anything lately. My guess is that it's a commercial engine. The 6.6L is going into the LCF 3500/4500 Isuzu based trucks. Nothing about a gas engine for the Silverado medium duty yet.
Check the fuses, make sure the battery cables and starter connections are tight. Also make sure the ground between the engine and chassis is good too. Maybe that new starter went bad?
C/K Man replied to GMdude2020's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)GM has had the same basic system used on the 6.6L on the DI 5.3L and 6.2L for many years now, and I have not heard of any major issues with it. In addition, I know GM did a lot of work managing crankcase vapor specifically on the L8T. I don't anticipate any problems. I could also comment that it seems to me that GM V-8's are 'tighter' than some of the competition's engines and use less oil......

1500? probably has a 4L60 transmission. Sounds like maybe the forward clutch is slipping, might not set a code until it starts to happen more often. Maybe oil pressure in the transmission is low. Sometimes you have to put some more miles on and wait and see if it sets a code.
Complete pouser or some real off-road capability? I really like the way they look, thinking about getting one. I have no illusions it's a Jeep Wrangler, but would want to do some mild off roading without getting stuck or leaving a bunch of plastic all over the place.
I thought I read somewhere that the 2020 HD's were supposed to have improved chassis corrosion protection, here it is from Motor Trend, in the paragraph 'Driveline Beef': https://www.motortrend.com/news/2020-chevrolet-silverado-hd-tech-seven-pub-ammo-bulletpoints/ The original poster of this thread's truck does not appear to have any primer or paint under the wax coating as stated in the Motor Trend article. The truck in question looks to have the same wax dip on bare steel GM has used on trucks since the GMT-400 series was introduced back in mid-1987. I wonder how accurate the Motor Trend article was. I heard rumors GM was going to change the corrosion protection process on the HD frames but have not been able to verify. New HD's at my local dealer appear to have to old wax dip process, nothing more. Maybe it's coming for 2021. I know, doesn't do the original poster any good, hopefully he will get a buy-back or at least get it repaired to his satisfaction.
