1999 chevy silverado 1500 4L60E transmission problems
I have a 99 chevy silverado 1500. It has the 5.3L V8 Engine with a 4L60E tranny. I am trying to figure out whats wrong with it. when pulling out it shifts really hard as if it was skipping completely over 2nd and into 3rd. I first thought I needed to have it rebuilt but then noticed that the speed-o and rpm gage wasnt working as well as the little area that tells you that your in Park, Reverse, Neutral, or Drive. not sure what thats called. I know that there is like 4 or 5 electronic switches for this tranny. So mainly what Im asking is do I need to have this rebuilt completely or could it be something electronic causing this? And Ive also tried having the codes read but it will not read. Thanks in advance for any help.
