How long should Transmissions last? (Page 1/1)

Looking at vehicles, many have CVTs that are rated "up to 100,000 miles" before replacing. Is that actually "Good"?!?

That seems kinda bonkers to me. I Think we will get a gas vehicle with GEARS...

Depends who made it then how bad then owner abuse it like other Auto trans.

in general terms...
Often Honda has problems from the start because made "cheap" while Toyota last longer.
Ones w/ real First gear last longer still because saves the "belt" from high loads @ stop signs/lights etc.

People abuse by never checking/changing oil or use any other oil not OE oil from Honda etc. CVT oil isn't same as other oils for most auto trans & very picky about base oil & additives in them.

The owner's manual of my 2019 F150 says the first service interval of it's 10speed automatic is 150,000 miles. Like many newer transmissions, it doesn't even have a transmission fluid dipstick.
Yep, seems crazy.

It will be a very long time before I consider the purchase of any vehicle with a CVT.
From what I can gather, Nissans are particular problematic.

AGREED. We had a Nissan 2013 Rogue, one of the only years they DIDN'T recall (but should have)

ABSOLUTE GARBAGE.

I have a 2018 Honda CR-V with cvt. Didn't notice that when I bought it. Bought it with 18,000 miles, right now have 118,000 with -zero- issues. Honda recommends CVT fluid changes every 40,000 miles, which I let the dealer do. Other than that, it's just oil changes, tires, and finally, front brake pads at 117,000 miles. And I have a history of destroying drivelines. Other cars, I've gotten 200-300K on GM transmissions without a hiccup. And one that died at ~100K.

Yes, early Nissan cvt's are notorious for their failures. My condolences. But Honda has been building cvt's in Japan for decades, so it's not the technology, it's the execution.

AGREED - The Rogue should have had a system which cooled the fluid, but didn't. They added it after ours started having issues, but it was too late, damage was already done... later model years came with the cooling system as standard...

I guess it depends on what they're more or less "guaranteeing" or suggesting. I've only had one transmission fail, and that was in a 1997 Pontiac Grand Am GT... and I bought the car with 65k miles, and it failed at 78k miles... so who knows. Of all the other cars I've owned over the years... stick or automatic... I've never had one fail. All of those cars went well over 100k miles. Like, my 2002 Ford Explorer Sport, I gave that car away with 186k miles on the original transmission... oooh, wait, I lied. Ok, that transmission failed too... forgot about that one. Haha... I bought that car with 32k miles, and it failed at 70k. Damnit. Ok, all the other cars have been awesome.

The most fatal (and most sudden) transmission failure I ever had was a 1961 powerglide in mid January, 1972 but, it was to be expected.
Ya just can't sit in neutral at a redlight (the only 1 in that little Arkansas town at the time) rev that powerpacked 283 pedal to the floor, with two 4 barrels and drop it into drive. A sudden lurch forward, a loud "KAPOW" I both heard and felt thru the floor board and coasted ahead just enough to see transmission case parts, gears and all that fluid laying in the road. The lever the gearshift was supposed to be hooked to just dangled beneath the car. The friend (Corporal Peterson) I was racing stopped 100 yards ahead and came back to see why I stopped. My modified 283 didn't quite make 300hp but made more torque than the powerglide could handle. T'was a long 55 mile tow back to Memphis, hooked together, my buddy in his new Z28 Camaro, and me in my '61 vette, held fast with the only thing we had. A set of tire chains I happened to have in my trunk, hooked end to end at 60mph over I40 with the top down in freezing weather with the heater going full blast to keep me awake. Yep, beer and a search for girls was involved. After I got a better built Powerglide (with a shift kit) installed, I pulled that intake off and put the single 4bbl Holley back on to help prevent me from doing such foolishness again. .

Imagine the kids of today reminiscing like this..."So I pressed the start button and the car took us to Lookout Point, I asked they/them if I could kiss them, and then later, we set the GPS for the local pizza and ordered a gluten-free plain pie using their app..."
