Is it possible for an average DIY'er to replace the sunshell in these units? I've heard its a weak spot in the 4L60E and I'm planning to replace it as preventative maintenance. Probably looking at replacing the 2/4 band clutch also. I'm not planning to heavily overhaul the transmission but I'm wanting to not remove too many parts if possible (valve body, clutch plates, snap rings, etc.)
4L60E sunshell replacement?

while transmissions are the only thing we do not rebuild 'in house' with our fleet, we still do enough of them to remember the ole 4L60E's!

They also have other beefed parts, do it right and it lasts forever. We actually had very little problems with ours, but i blew up the one in my Impala SS about 3 times before I finally had it professionally rebuilt with aftermarket stuff. It was fine then even behind a 409 stroker!

I'm not comfortable rebuilding an auto trans. I had a TH350 in and out of my elcamino 3x before I gave up and took it to a shop.
The answer to the question is that you have to take the transmission completely apart to get at it, so unless you are experienced at transmission work (not a typical DIY-er as you specified) and equipped to do this particular one, the answer is no.
It's not something I would attempt.
That said, the original 4L60E in my truck went 200k and it didn't die from the sun shell.
The second 4L60E went 130k and also did not die from the sun shell.
Neither had any fluid changes and going from D to R and R to D while the truck was moving was the rule, not the exception.

+1 The Chevy truck dealer where I bought 2 of my Suburbans actually had an in house "expert" rebuilder who would do the whole job for $1500. He was with them for 25 years and would do 3-4 of them a week aside from his normal duties. I thought that was a bit unusual to actually have enough trans failures to keep a full time employee on it. As for the OP, find a guy who has done 1000 of them and then get all of the heavy duty aftermarket parts and have it done right.

Not really a DIY project.

You did not inb4 correctly, therefor your argument is invalid
Seriously though, I would never attempt to rebuild any part of an automatic transmission myself. They are just too complicated, I'll swap one out myself if it's a RWD car (like our jeep was) but I'll leave the actual rebuild to a pro.
Side note, is this what could be going on with Js 4L60E?

Are the later 4L60E (2009) and up trans any better?
IIRC, my POS Safari has a 4L60E. It also says that anything 1992 and later was a 4L60E as opposed to a 4L60, and that the E was dropped when everything went electrical anyways.
I myself was planning a fluid swap with 30%-50% Royal Purple Trans MAX fluid. I found the line going to the radiator and it should be a cinch. Adviseable? It shifts fine, but I don't like 200k virgin fluid. Want to change it.

Oh, and http://helpwrench.com/forums/showthread....Pics-and-Tricks This is a guide as to the 4L60E. I Googled it to be helpful.

So I may have problems with the 4L60E in my 2012 Silverado?
watch this video to see what you are in for. i dont see the point of tearing it down and not doing a complete rebuild.

Relax, man. We had a ton of these in Silverados and NO issues. The only one I blew up was in my Impala SS at the strip! Remember you never hear anything from the many thousands of customers who never had an issue.
Your 2012 has numerous updates and will last a long time behind that 4.3 V6!
