At more than 225k it seemEd like a good idea to completely service the transmission. So I laid in 14 quarts of ws synthetic compatible fluid, crush washers, a filter and o ring and gasket, some 5/8” id and 1/2” id vinyl tube, a quart size pumper.
watched the very helpful video from

and got started.
ran a few errands to get transmission up to 200 deg.
removed my skids
popped the drain.
got about four quarts dark as satan’s heart.

should have done this baselining sooner.
be very careful With the pan bolts. They are 65 in lbs (5.5 ft lbs). If they resist you’ll twist them off easy. Suggest spraying all over course of several days above the pan at end of bolts to make sure they aren’t rusted in.
i had 10 come right out, and two resist. these are the outside rear corners. The reason is that the air con drain drips on them.
I twisted one off before I knew better.

The second was able to work free with much difficulty. For reference I wa s using a 1/4” short handle socket and was up by the head and still twisted it off.
i tried to drill it out, but didn’t make any progress and gave up. 11 out of 12 is really good, right? Sucks it was a corner bolt.
got six qts out of pan and drain and filter.
put that back together And put six qts back in.
ran three qts out the radiator after locking the thermostat. still dark as the abyss. Will pick it up tomorrow fillign those three and running three more out. Total capacity dry is 9 qts so I think nearly flushed .
no pics was in tranny fluid gloves the whole time. Video is better than any pics I’d have anyhow
