Expected transmission life span

[EfiniMotorsport]

Does anyone have a ball park idea on the expected life span of the 4L65 tranny? I'm at 108k and a buddy of mine that rebuilds transmissions says it's usually about 100-110k. I don't know if that's the life span of the ones he sees or if that's about all they last.

I’m at 125k and runnin strong. Beat the piss out of it and am also runnin 37’s with 5.13 gears on the original tranny.

I straight broke mine at least 3 times, I recommend not flooring it like your trying to escape the depths of hell with a pitbull nipping at your ass constantly. I think the first time it was in the 90k range, put a factory one in it lasted for just over the year warranty broke it, had it rebuilt cheap it didn't last even a year again broke it, I also broke the rear end 3 times, transfer case twice. finally put a eaton Detroit in the rear end then I just ate the bearings up but it didn't break again, got a transfer case from powertrain products it was good no problems, had the transmission rebuilt right but I still blew the manifold seal after that is lasted a couple years and I broke it again and it would just roll in park. since then I've calmed down a bit all that stuff cost's money lol, now I just break tools and buy a warranty it's cheaper.

I my factory 4L65E died at 86k. Was a sad day.... had it rebuilt by a shop that is pretty decent. In February around 95k on the odometer, a valve failed and wouldn’t allow me to manually downshift from drive to third, and so on. He replaced the valve and refilled fluid under my trans warranty, and it’s been fine since. I’m now just over 106 on the clock and it runs great. It really all depends on how you keep your transmission maintained. After losing mine so early I watch my fluid like a howl. Always making sure the right level amount is in the trans and will have it serviced regularly. If you keep your trans maintained you can probably get it to last longer.

i always used to joke that the 60e family seemed to either die at 90-110k or they would last just about forever.

 

[Doubeleive]

yes-what he said above, have it serviced regularly, I do mine once a year like clock work seems to be working out in my favor so far

I'd be a bit more optimistic than most with them... 150-200k is when just about every one dies.

All depends on what the SUV is used for. 4L60E/4L65E dont last long being used to plow. Towing will speed up their death also. There are things that can be done to help for being used as towing. Tranny cooler, change fluid regularly, oversized tranny pan, watch the temps and keep them down, never tow in 4th especially when doing hills/mountains.
Average joe use and they should last around 120k give or take. Abuse them and youll be like the guy above that has it in the shop sucking out the contents of his wallet every other month.
They can be rebuilt substantially stronger than factory for a minimal amount of cashola.

ya my case is a rather extreme example, I abused mine severely, I was even told no one had ever seen a broken transmission like mine was and this was coming from people that worked on them for several decades. I had my license suspended/revoked 3 times back to back during that time it took me 2 years to get it back so mine was easily in the 1 percent of what CAN happen, and yes it does nothing but eat your wallet doing that.

Those responses don't fill me with much hope. On the plus side I can get a rebuild/upgrade for a little over $1k. My buddy does all the rebuild at a tranny shop so I just pull it, bring it to him and he usually gives it back to me in a day or two. He upgrades the weaker parts anyway and will beef it up from there if I want.

My folks have driven nothing but 4x4 GM pickup & suv since I was in grade school... A couple of each in green and a couple more in white. My mothers sister & her son both have 4x4 GM in the 2007 or '08 NNBS, 1)suv used to pull a loaded trailer every weekend and the kids pickup has a million miles driving between home & where he goes to college. All high mileage vehicles, some purchased new & some purch used with never a transmission problem to-date that I was made aware of. And I would know. I think that you have to be really ******* a 4L60 to have a failure. if you are easy on it and change the fluid every once in a while there is no reason for failure, espc if you are not towing/hauling with it.

I got my 2011 SSV with around 119k. Those were all hard cop miles. The vehicle is set up from factory with an extra engine oil and trans cooler. I went to the dealer right after I got it and asked them to do a fluid\filter service. They said come back at 150k, it will be fine. Sure enough, I got the trans serviced at 156k. the fluid looked a little dark but no residue, shavings or bits of rubber.
A thousand miles later I break the rear end. The transfer case had a lot of play in it so I had that done as well.
The transmission always seemed to have a mind of its own. The fluid change smoothed it out a bit but I still feel that it will have to go eventually.

My 2000 4.8/4L60E Silverado went 180000 before it died. Had the hard 1,2 shift before it quit.

Hard to say. Mine went at 136 but my friend has a 2001 sierra with the same tranny (i would think its the same) and is over 200k with the original

Drop it off Friday and come and pick it up Sunday night and I guarantee I can have you picking it up with a tow truck on the side of a road with the transmission nuked. They arent hard to destroy if you drive a 5000lb truck/suv like its a Vette.

My mother in laws tahoe went 230k with the original tranny before she suddenly got stranded on the side of the road with a back glass covered in atf. She towed trailers left and right with that thing.

Mine went about 175K, but I pull my boat and camper all the time and my tow/haul button hasn't worked in at least 3 years. I fixed it after putting the new transmission in...

Holy crap you drove 2000 miles in 12 minutes! That's flying!
