Installing a shift kit in a 4l80e I am looking into a transgo shift kit for my 4l80e and was wondering if this was something I could attempt myself. I have access to a lift an a huge assortment of tools so thats not a problem. How involved is this? I do not want to screw something up an ruin my tranny. Thanks

I would have to say the TransGo for the 4L80-E has a difficultly level a full point above the kit for the 4L60-E.
There are quite a few holes that have to be drilled into the valve body with the 80 kit, versus the 60 kit which requires zero. Both kits have you drilling some and plugging some hols in the separator plate. The 80 kit also has a full page of mods to do if the transmission is torn down for rebuilding. These can of course be skipped if just the pan is coming off.
As far as tools you'll need some circlip pliers, needle-nose pliers, sockets and speedwrench, pin-vise for tiny drillbits and a small electric drill, brake or parts cleaner, new filter, gasket, and some fluid. I also found masking tape helpful for covering up areas of the valve body I did not was drill shavings falling into.
If you are mechanically inclined you can do it. I would not expect someone not comfortable with machinery and tools to be able to get through this install. If you're afraid of it, that is probably a sign that you should hire some help.
