Transaxle oil change

Ideally, I would advise 30,000 miles, then 90,000 miles then every 90,000 miles, most metals seem to be suspended early.

My dealer charges $110, but shipping to Mississippi seems impractical. (any gen 3 'how to' will show you how)

 

I did a first change at the one year mark, around 15,000 kms. I think it was warranted; the drained fluid looked quite dark. I then went a couple of years, did a second change around 40,000 kms. This time it looked quite clean/new still. I'm a bit past 5 years and 57,000 kms right now, resolving to do the next one around the 7 year mark.

My plan, considering regular miles being put on the odometer:

first year anniversary: change
(go two years)
third year anniversary: change
(go four years)
seventh year anniversary: change
(carry on with four year intervals)

It's a relatively easy DIY, about on par with an oil change. The main difference being that the car should be raised and level. The fill and drain bolts are a little oddball, are socket cap screw style, with 10 mm hexagonal pockets. They have washers you should replace, and the torque is 29 lb/ft. The simplest way to get the new fluid in is to snake a funnel with 3' hose extension through the engine bay, from above. Just fill 'till it starts coming back out. It'll take around 3.5~ quarts or liters, so you need 4.

Last time I purchased was in 2013, liters of Toyota ATF-WS cost me $9.32, and the washers were $1.99 apiece. (Canadian dollars)
