sorry i don't I've taken quite a few apart before from other autos and couldn't visually see any issues, they are supposed to be vacuum tested. I actually have a wholesale automatics valve body on the way for my A442f. i just saw your other thread :A442F Slipping -...
I once owned a T100 with a A340, had the same issue, cleaned them. got me about 10k miles then acted up again, replaced them a second time and added an inline filter. I sold the truck but still see it around prob 40k more miles on it now still working good.
