I made a post on here a while back around Christmas with some questions about my transmission that lost some gears and got some really knowledgeable input from some great people. As of that post the 3rd and 4th gear were unavailable with slipping in 2nd. Since then, my step father took it on a test drive because he...didn't believe me that it was broken?? and came back 30 minutes later in reverse as 1-2 were now gone as well. Anyways, at the time I was planning on looking for a junkyard swap but I got to talking to a friend of mine who has rebuilt a few GM transmissions who said he would teach me how to do it if I bought the parts, which leads me to todays question. What parts kits include everything needed to restore my 4l60e to its stock state? the truck is an 04 and a lot of the rebuild kits I see only go up to 03. What I'm seeing online there are a ton of different kits, some offering upgrades, some with extra parts like new sun shells which I'm not sure I need (unless an old one is cracked, right?) and pretty big differences in pricing that I'm having a hard time understanding. I called around about getting the torque converter cleaned but it seems my best option is to just get another one (new or rebuilt?). Does anyone know of a complete rebuild kit that includes everything for a stock experience without any special upgrades that goes for a reasonable price. I will end up having to sell the truck soon so I don't want to put a bunch of money into upgrades that I likely won't get a return on. Thanks for reading and I appreciate any feedback on the matter!
