I was wondering how many others had ever had an issue with theyre computer causing an over pressure situation in the trany. I have a 93 Suburban with a 5.7 and 4l60e that got rebiult about 8K ago. It has a 24K/24MO warranty on it and reverse was going out. I took it back to the shop and got told it wasn't the trany, it was the truck. It was running almost 2x normal pressure and had stripped out the luggs in the trans. I just wondered if this had happened to anyone before or how offten it dose happen.
