Changed the gears in my 95 Silverado. Speedo is 10 mph off and i dont know how to adjust it. I know with the vortec trucks it can be changed by the computer. Any tips on how to fix this would be much appreciated.

Only way to adjust it is by adjusting your drac/vssc. I like the old write up better as they showed you how to put in "dip" switches, which is what I did to mine. But here is a link...

DIP switch way is best way. Keeps you from having to move jumpers around all over again trying to find the best setting, as the one the table gives you isn't always the most accurate. That 1995 model probably has two banks of 7 jumpers which are mirror images, so a pair of switches will need to be installed and set accordingly. Easy work if you can handle a soldering iron, and costs practically nothing.

My 1995 has the two banks of 7 jumpers, but can be replaced with the drac that only has 1 bank of jumpers. I have several of them if you need em. I wish I would have put a DIP switch in. Took me several tries to get mine right. That chart/table was way off for me.
