> This is an aside, but transmissions are often replaced by a dealer.

Really? I mean I know dealers do some transmission work, but everything I can tell says that transmissions generally will last far beyond the warranty.

By the time it is time to do something the car is on the 3rd owner. Very little of such work is done by the original dealer. (though in the case of some heavy trucks transmission wear is common enough that the dealer will automatically rebuild every single one they take in - but these are not the original manufacture dealers but an independent used dealer) Most will go to an independent transmission shop, even smaller dealers will take a car needing transmission work to an independent shop because that is specialty requiring training they don't give their mechanic.

Even at that, transmissions have enough non-wear parts that the manufacture will rebuild them in general. There is a reason when you buy a transmission from anyone there is a core charge: they send it back to be rebuilt.

Like most major components in cars these days if it fails early, it's likely a common manufacturer defect.

Nissan CVTs for example, are known to die multiple times before 100k. Nissan even bumped up the warranty to avoid a proper recall.

People are offering rebuilt transmissions, but like you said the average individual is at most going to use their transmission as a core for a rebuilt one that very specific places make.

The dealer isn't going to point them to a transmission shop (or take their car to one)
