The 6L80 disease hit our Silverado - full trans rebuild at 113k miles 🤬 

Yes sir, got an 07 Tahoe myself with 200k on the 4L60, no issues. Simpler was better!

Definitely can't hurt to check on it! During the first two transmission services I did, the fluid in the trans pan was nowhere near as dark as what was shown in the video. Once the converter clutch starts to go...they go really fast. Sonnax makes a billet converter retrofit kit that uses your stock converter but replaces the poorly designed parts with much stronger ones, so that's definitely a worthwhile upgrade if yours is still in good shape and you don't want to spend the money on a full converter. Thanks for watching!

get it tune .. it will save you thousand of dollars...

Ain't that the truth...I'd even take another 4L60 at this point, the one in my Tahoe has 200k on it and hasn't missed a beat. Better yet, they should just stop worrying so much about the EPA and just make reliable products...wouldn't that be great! lol

@@AllThingsMechThey could have the EPA standards and still have reliable products, I think they get too high tech

Definitely agreed. Biggest things seem to be 1) trying to shoehorn too much tech into a too-small package, and 2) trying to push the envelope to see how cheaply they can produce something and still make it reliable. Both seem to be happening here, but it's usually #2 that causes the biggest problems.

@@AllThingsMechYep, I guess for the most part we are better off if you consider the power we get with the high MPG now, Brings back memories of adjusting points and replacing spark plugs @ 10,000 tires @ 20,000, oil @ 3,000, valve job @ 30,000!

No, it doesn't. Deep first and tall sixth make for a better truck than the old 2.52 or 2.48 first and no OD.

I sucked some of the fluid up just to see what it looked like before taking the time to drop the pan, that's all. Wishful thinking I guess, but I'm a fan of taking the least invasive approach to a repair. Once I saw the color of the fluid, the pan came off the very next morning. You also have to remember that this was before I had done all of the research and realized how widespread of an issue this is.

With all due respect to your many years of experience, I encourage you to do some research on the 6L80E and educate yourself a bit on the JMBX converters used in these vehicles - starting with the article from Sonnax that I've conveniently linked for you in the description of the video. This is not a new issue, and is well documented. 1) No, this truck isn't driven hard; its my wife's daily. 2) The bands and clutches in the transmission were not out of adjustment, and have nothing to do with the failure here; it's isolated to the TCC within the converter, which comes apart and sends shrapnel through the entire trans. Please watch the video in it's entirety, and then go do some digging of your own on the issue and see what you come up with. If you can come up with a different cause of the failure (other than what you've already suggested, which was not the case), I'd love to hear it...but keep in mind that I've already gotten the issue fixed and have spoken at length with the shop about what failed. What I stated in the video regarding my trans is not conjecture or opinion.
