    NEED HELP 2003 Trailblazer transmission

    Do a search on Transgo shift kits. The kit comes with metal actuators to replace the stock plastic ones which crack over time and allow fluid through them, which can cause sloppy shifts. I put one of these kits in my old '03 TB and it made a dramatic difference. That said putting it in involves...

    Looking for a unique idea for a new mod?

    Resident. It's been a while but I the sales stat was the entire state. From a legal counting perspective, GMC and Chevy are different brands, but they are the same trucks save for trim and a few options. GM far outsells them all. That said I've driven mostly GM my entire life, that interior...

    I'm a little surprised it's not a Chevy. Chevy 1500s outsell F150s in WI.

    Auto 4WD strangeness, help me confirm my thinking

    I don't disagree which is why I took it in. They said if the rear wheel is slipping while turning it's going to be engaged and the wheel hop is showing it's actually working as it's supposed to. When going straight I can't feel the wheels slip like I could on my '08 Sierra and my TB. But I know...

    Auto 4WD strangeness, help me confirm my thinking

    Just a follow up. The dealer says it operating normally, binding is normal when the wheel is turned, even in Auto 4WD if the system is engaged. So, it doesn't look like we're getting any more heavy snow, but next time I use the system I'll turn it off when turning corners. That said they at...

    Auto 4WD strangeness, help me confirm my thinking

    I talked to a dealer today, not the one I bought from because of the distance away, but one I've had good service from before. They said that doesn't sound right, like it indeed going into 4HI. I have an appointment to drop it off next Wed. Thanks all!

    Naw, just normal acceleration. I mentioned the CPO because I'm planning to get it in, I just wanted additional thoughts. I really appreciate it!

    That was my understanding. I was thinking about the age of the fluid too. My guess is due to low mileage it was never changed.

    Auto 4WD strangeness, help me confirm my thinking

    I got a 2016 Silverado Z71 LTZ 2 about a month ago. CPO and 37k. I don't think the previous owner ever had in snow or salt. This is a rust free truck. I mean, really rust free, which is phenomenal for any 5 year old vehicle in WI. The only rust is a little on the muffler. I also don't think the...

    2006 Denali Battery type

    I'm actually surprised 48 volt systems are not already common. I read a number of years ago that manufacturers were going to start using them. Both my old 2008 Sierra 1500 and the 2016 Silverado 1500 have top posts. They are an odd design though. The posts are sunk in on the corners so that...

    2006 Denali Battery type

    Funny this conversation comes up now. I just bought a very low mileage 2016 Silverado LTZ a few weeks ago. We had sub zero weather over the weekend and the truck turned over slow. I'm putting a new AGM battery in this afternoon. After lots of reading yesterday this seems like a good option, it...

    Longevity of the 4.2 and 4l60e

    That's awesome if you have the time to do all of that.

    Longevity of the 4.2 and 4l60e

    I will say this. In 5-10 more years the issue becomes weakening spots of frames and other structural components. The other thing that happens is parts start to become scarce. I had a '95 Suburban that I bought with 107k miles. I think it was 8 yo when I bought it. I drove it until it had about...

    TSB# #100601008G : Excessive Oil Consumption in AFM V-8 Engines 2007-2011

    Oh yes, I found this about a year after I got my Sierra (it had 85k back then). My intention was to get the updated valve cover but never found the time. Or the desire. So I pop $14 every 6 months or so to replace the #1 and #7 plugs to prevent a CEL and limp mode. It's got a 160k on it now and...
