I am well aware of the service manuals recomendations. I am also aware of who wrote that manual and the real world implications of following it. There is such a thing as "planned obsolesence" and looking at the factory band and the service manual it just kinda jumps out at one.

As for the band strut falling out, that was due to a misadjustment to start with, or the lock nut coming loose, or a failure in the band apply linkage. If all the pieces are in good shape, set correctly form the start, and locked correctly you can burn the band material off down to metal and the strut will still not fall out. There is not enough band material to allow that.

On my 05 I validated the band adjustment at 10k. It was almost perfect and still had plent of threads showing. I ran to 105k towing 10-15k frequently with power level up to 450 hp. I burned upo the direct clutch pack and when we tore it down the front band was perfect and well within the intital setting specs. Set it once every 100k and if everything else works correctly it doesn't need frequent adjustment. If it does it is a symptom of another problem.

Here is what the OEM band looks like. It has very little material to scrub off. If you have to adjust frequently it will be down to metal and eating the drum. I am not advocating never adjusting, just not using it as a cure for ANOTHER problem that will eventually trash the trans.
