To say that clucthes (sic) in an automatic trans never wear is absurd.
If you’re referring to what I said, well, I never said that.
What I said was THIS:
Automatic transmissions rarely wear out from simple clutch wear. The clutches do not slip when applied. Transmissions wear out from some hydraulic failure from worn or hardened seals. Seals wear more from heat and old fluid, not from shifting. Worn seals leak pressure, and then THAT causes clutch failure.
And it’s so true that I’ll say it again. Even in the full throttle “power shift” you suggest, later model transmissions raise application pressure, making sure that the clutches STILL don’t slip.
Automatic transmissions fail far and away more often from hydraulic failures than from simple friction element wear. If the friction elements are worn out, it’s not generally from simple use, it’s from inadequate pressure causing them to slip.
