Iím debating what to do about my 2006 buick Rainier awd 4.2 with the 4L60E transmission. Truck has 192k original eng. & Trans. Both eng. & trans. Are running well and I feel like the engine could go another 190k. Iíve seen a few of these trannyís go 160 to 190k then need a rebuild. I installed an oversized pan with drain plug around 50k & have changed out 5-6 quarts max life atf every 25k or so. Probably 80% hwy miles since new. Anyone seen these units go 250k+

If it runs good, just keep doing what you been doing. A used one if something does go wrong is easy and fairly cheaper.

Both my cars have a 4L60E, one has 120k on it one has almost 180k, no issues.

Then again the ones after 2002(?) I think are much better than the older ones.

If you don't tow or haul heavy loads with one, they seem like the newer ones aren't bad (and a Rainier isn't that heavy)-but they're really not meant for trucks, vans, or SUVs that haul a lot of weight. Keep doing what you're doing, at 192K you already have beaten the maximum mileage that any of mine made it!

Sounds like you are doing the right thing. Is there a filter that can be replaced as well? I would do that every 50-75K is possible and clean out the crud at the bottom of the pan as well.

You're in a good place.
1) You maintain your trannie.
2) Even the old ones were not too bad(?). As mentioned, you have a newer one.
3) If ever it does die, there are soooo many out there any trannie shop can order a rebuild and swap your out in a jiffy.

Mine has right at 160k on it with no issues. A friend of mine has the 4L60E in a Trailblazer with 198k with no issues. They are a good tranny, i wouldn't worry if i were you just keep on going until something goes wrong then R/R.

I have a buddy with a 2003 Suburban. He bought it brand new and has done drain and fills on the transmission every 60-75k. It has 260k on it and still going strong.

I believe that trans was used in 3/4 ton trucks so it has to be good and strong, no?

I remember tending to a neighbor's 2001 Camaro. He let it get >1 qt. low and in a particular configuration (the position I first saw it in) it didn't go into gear for a full minute. That's when I checked the fluid.
I was amazed and angry (as I had no way to beat the owner-and get away with it).

It ran perfect with a full belly. They sold it

My experience is based on my transmission guy stating that literally every light duty 3/4 ton Chevy or GMC work van he maintained smoked the 4L60E by 150K, and my departed C1500 Suburban ('94, TBI 350) had a rebuild with the 7 clutch update due to the previous owner killing it pulling a 22 foot cuddy cabin boat regularly, even with the factory tow package, cooler, etc. In LIGHT duty non-commercial applications, I would think 250K would be possible-but a supplemental cooler and temperature gauge would be a VERY good idea.

My 2005 1500 Avalanche just rolled over 193,000 this week. Siphon and fill about 4 qts a couple times a year with Supertech High Mileage Dexron. Pan has never been off. Never towed. No problems yet.

I think you are in good shape. My 1997 GMC 1500 has 245000 on original engine and tranny and it has no problems at all. I did add a deep pan, spin on transmission filter, and a tru-cool 40k transmission cooler behind the condenser. I have towed a boat and camping gear (about 5,000 lbs) in 100* F temps up mountains and it ran great (always tow in 3rd). I also took it from CA to VA with no issues.

I have found if you keep it maintained and cool, it should last a long time.

They have been known to go 250K with no service at all under light duty use....Especially the 2005 & up with better (Dex VI) ATF.

Being behind a 6 cylinder & your taking care of it.....It could last a long time!!!

Debating what to do in terms of what, replacing the vehicle or trans?

I wouldn't do either until problems actually arise. You've done all the right stuff. From what I've experienced, if you do *some* type of trans service at that 30-50K mile mark and then KEEP maintaining them, a higher than typical lifespan will result.

We have a 2004 5.3 Silverado at work that got close to 400K on the original trans. Lots of highway miles, stingy maintenance. A 2004 Sierra 5.3 at work got about 300K and probably would have been usable for a while longer, but the trans was replaced before it got really bad.
