i was wondering if the transmission went out or it hopefully something else. i broke down a couple of days ago, i went to go see what was wrong with it and i put it in drive it just made the loud grinding noise from underneath the truck and i wont go and where unless its in reverse or in 1 or 2 gear but in those two gears it still makes a very loud grinding noise but not in reverse. Thank u for any help.

Hello, I'm Danny.

Yes, it sounds like you had an internal hard part failure. Just to give you an idea most transmission repair shops will not just do a quick fix but rather they will require a full rebuild. A transmission like your 4L60E will be in the ball park of $2,000.00 for a rebuild to give you an idea depending on your area and what kind of repair shop you take it to. Here is a tutorial showing how to remove and replace a manual transmission which is similar:

I've attached picture steps below on how to remove and replace the automatic transmission on your Silverado. Hope this helps and thanks for using 2CarPros.
