Changing transmission fluid with high mileage

Gaskets, crush washers etc can be reused, BUT, the only way to ensure they do not leak or malfunction is to replace them and torque the binding nuts/bolts to spec.
If you are going through the expense and time to do something, why be penny foolish.
I would say plan ahead and have the reeded parts ready.
In a pinch, go ahead and reuse, but if the gasket is buried then take the extra time to get the replacement. I generally go to my dealer to get these. [I know they charge almost $2 for a 10c crush washer].

The pan gasket is a cheap part..get a new one and prep surfaces clean to avoid leaks. Crush washers i typically flip them and lightly sand with fine grit paper if they are not smooth after cleaning, then torque to spec.
Due to the area of work and its exposure to sand and dirt, cleanliness helps alot and ensures a good seal. Though it seems compulsive, i put all the removable fasteners into a small jar and shake around with degreaser and pat dry. This ensures me that i can torque correctly during re-assembly because of the light torque spec.

yeah cheap but since i was told to just clean the metal filter i forgot to order the gaskets. i didn't want to wait so long for shipping and was already getting antsy from having put off the DIY for several days so i started the job. i remember when i changed my engine oil couple weeks ago there was no washer. it's nothing serious but the area around the plug is a little dark so either it isn't tight enough or it needs a washer (or is something else altogether). definitely isn't an issue but i'll get a washer to put on next oil change. strange to be how one plug is hex and one is allen wrench when they perform the same function. just another socket i needed to buy 
at least the washer is the same.

hi, I was wondering how’s your transmission now acting after you did the drain n fill because I’m about to do it very soon at 110mi and that’s my first drain n fill ! Any help would be appreciated
my FWD rx has 150,000 on it and transmission fluid has never been changed. it sounds like changing is the best thing to do despite lexus manual, and from what i've read think several drain and fills w/cleaning is the best way to go about this given the high mileage and lack of service.
since there are many reports of tranny failure right after a fluid change, i'm wondering if it's ok to check and clean the filter often during the days following the change without adding fresh fluid each time. since i don't want to introduce too much new fluid too quickly into the vehicle, would it be ok to drain and fill once, then each 100 miles or so check and clean the filter (replacing with the same fluid that was drained) to rid of any large debris that may have come loose? then do the same thing over a couple times until most of the fluid in the system is replaced.
i want to do everything i can to prevent failure. what's strange to me is how people who have been doing regular changes from the start have had their tranny failed while mine is still smooth after 150k...
