i never said it was lifetime - it is not... nothing is lifetime... well... maybe the pyramids...
the problems with those gears is that as they wear off and contaminate the fluid, the material builds up inside and becomes part of the fluid - if it has not been changed early in the cycle, those chunks of the metal shavings inside actually "help" prolong the agony of the system... however, once you remove them and fill the void with the fresh fluid, the worn gears do not have the gunk to stick to and they start to slip...
i am tryinig to say, that if the tranny was not serviced before 40K, then just let it be... if it was serviced at that time, then do the regular changes at regular intervals..
it is like dental clean up - the moment after the clean up, the teeth are very sensitive as they protective layer of "gunk" is removed... I am not saying that you should stop doing the semi-annual dental clean-ups!!!
just a reference to the tranny!!!
