According to the comments section in the article I linked, the solenoids usually give up before the friction surfaces.

That really depends on the Transmission. Look at a 4L80E VS a 4L60E.

I have burnt up a few 60's in my 11 second F-bodies. Never any selnoid stuff, but you look at a 4T65E HD in like a Grand Prix GTP/Regal GS. It is the luck of the draw. Genearlly a shift kit will help with the life of those, but they have selnoid and hard part problems too.


Bottom line is if you want to increase cluth life you up line pressure, and you may get hard, crisp, faster shifts and a lot of the slippage goes away but other stuff could wear out depending on power levels. Most modern transmissions do a pretty good job on the stock tune with stock line pressure and clutch life isn't even a concern or hard parts for that matter until you start adding power.
