Serving 4L60e’s for dinner

[KaulinGraves]

Hey all, I pulled this trans from an ‘07 Classic 4.8L 2WD from a salvage yard and intend to rebuild it for my ‘00 4.8L 2WD. I’ve done what research I can do to find and make sure this would at least be a good “core” for a rebuild trans. I can tell somebody has been in it before as the pins don’t correlate with the correct year of the truck, but the stamped code is for an ‘07 on the casing. If I remember correctly, the green 13-pin male end is until ‘03 or ‘04 as they had an internal speed sensor which changed to a white 15-pin. Even the female end is a 13-pin. Either way I have a rebuild kit that includes a 13-pin harness that I’m going to already replace it with. Right now, I just transferred the trans from my truck bed, to my kitchen floor XD. Let’s hope the Mrs. doesn’t notice. Wish me luck in the process.

If I said something incorrect, please let me know, I’ll take all the information or criticism I can get to make sure this goes as smoothly as possible for a first-time trans rebuild. Thanks

Ideally, you want a unit that's never been apart as your first build. But you gotta do what you gotta do.

Did you get the manual? May be a good idea to print it and have it handy.

I think I mentioned somewhere on this forum before, but you need to have 3 areas generously sized: the case on a stand you can rotate (I welded a copycat gizmo to mount to my engine stand), an area for all the sub-assemblies (a 6 ft foldable table works well for this) and a dedicated cleaning area (parts washer is nice, but I've used a 5 gallon pail with paint thinner with some brushes.)

Familiarizing yourself with all the sub assemblies is what you should do first. Try learning the correct names. Clean parts twice before taking a good at things with good lighting. If you need to, get a magnifying glass or take things outside to look under natural light before calling something good or condemning it.

Practice reinstalling the subassemblies back into the case. This will give you practice and confidence and help develop how drums sounds/feel when they are fully seated, for example.

Good luck and may the Force be with you!

I’m probably gonna have to be working off the back of my truck bed under a tin roof in the yard honestly, unless I rented a storage unit to work on it. I’m willing to take my time to do it right the first time. I’ve found several guides online and even have the steps written down and typed down(that I plan on printing off) to disassemble, reassemble, what to check, and what tools I need for each step. The only thing I haven’t bought yet is a torque converter and trans cooler(I don’t mind buying the latter at a later point in time, either way the truck drives in every gear except 3/4). I have a scribd.com link to a 4l60e manual here:

I’ve looked to find others but most of them seem to be this one. If there’s another you suggest, I’ll take a gander at that one too.

PS: At my current state of accessibility, I don’t have an unopened core to work with, even the one in the truck. Either way I’m going in blind with not much more than a “road map”, a torx plus bit, and a pair of snap ring pliers XD

I have the 4l65e in my early 06 and I heard mid year they changed to the 4l70e. These are supposed to be much stronger and heavier duty. The modifications needed to update your 60 to a 65 or 70 are supposed to be simple. You may want to look into it.
