Years ago on this web sigh, there was a formula to correct the inaccuracy of the speedo in a 1988 full size truck. It involved resoldering some of the jumpers in the box behind the glove box. Well as things happen, my computer crashed and I lost everything. Now I am in need of this program and was hoping someone would have a copy I could download or direct me to where I might find it. Any help with this would be appreciated. Thanks

  I turned 72 today. My day began with a trip to the pharmacy to pickup meds for me and the dog and then a stop at my chiropractor before heading home. Once home I started the job of replacing the rear brake pads and one rotor on our 2018 Silverado which will probably end up taking me 3 days to finish, gotta pace myself you know. Sometimes I question myself on why I still do most of my own repairs but if I wasn't then it's more than likely I would be sitting in front of the TV all day. It seems like the list of things I need to do gets longer no matter what I accomplish. I'm not complaining but being retired was so much easier when I was 62. Peace

  google "bathub failure curve". Basically, any part of the vehicle can fail at any time. It starts off as being more likely (early failure), then the failure rate goes down (but does not go to zero), then it goes up over time because it wears/ages out.

  I went from every other day to about once in five since the rain abated. I'm not unhappy about that. Took most of the month for the ditches to dry enough to mow.

  We've done a bunch of them. Very common failure. They don't sell the park position switch separate from the shift control assembly which is stupid, because they ended up selling a switch on some other products like 2016-2019 Malibu, 2018-2019 Traverse, 2019 Blazer, and another car or two as those were having the same issue for years (but these have a console mounted shifter not column mounted).
