4L80e Transmission HD2 kit
Pretty straight forward with a little homework to see how its done if you're not confident in transmission building. Parts are high quality, packaging is clean. Shipment was really quick! Though this was gonna take longer than a valve I ordered later to come in.

Great for the 80e
I've bought three of these. I never use the pressure relief valve but the shift kit is great. I never have issues with anything out of them.

Check it when you receive it
I orders this a few months ago and never opened it til this weekend when I was going to install it. The separator plate was jamed into the one gasket and rip it so now I need to find another gasket

Highly recommended.
Can't go wrong with this kit. Read the instructions and follow them closely. There are a few things you need to drill. The size of the hole makes a big difference and they only give you the medium size drill bit. You will have to get the other suggested sizes for the other options but for a work truck the provided bits are fine.
