So a lil while ago, my Trans lost all gears. I have a 2007 Yukon with the 4.8/4L60e So I’ve been searching for a replacement. I considered just replacing the pump. But don’t wanna just throw money at a trans and can get a rebuild. (Trying NOT to rebuild) So before I get to that point I searched all over the web and junk yards for this trans. What years 100% work? I mean bolt up and go. Only 07-09? 07-13? Is this a 13 or 15pin? Purple or green plug? ISS or Non-ISS? 300mm? Can I use old TC? Thanks for all help.

Not too many questions on the 4SP lately. @NickTransmissions is the MC of transmissions around here.
Any late 2006 to 2008 with the ISS will work, assuming the particular transmission you buy is in working condition (gigantic assumption when it comes to used 4L60Es). Do not buy anything 2009+ or early 2006 and older (non-iss).
If I were you, I'd rebuild your transmission, install hydraulic upgrades, new electrical components in addition to new clutches, steels, band, bushings and converter. Your 4L60E has a TLBX converter given you have a 4.8L so make sure you put a replacement TLBX converter back on. DO NOT reuse your existing converter and definitely DO NOT BUY any converters from chain auto parts stores like Autozone!!!
