Transmission Fluid - My car is ruined - help

[jekqmb]

Doing a drain and fill does not get particles out of the tranny as well and can cause even more build up, get a fluid exchange.... No pressure on the tranny and gets alot of old nasty debris out. I'm an ASE certified tech, i do not like doing drain and fills....I always suggest an exchange in an AT. Drain and fills were okay back in the day when filters were changed out...

Are you sure about that? I've seen several transmissions ruined by 100k because they did a couple of flushes. When I pulled the pans, filters were clogged...transmission was spic-n-span, but filters were trash, probably because mechanic wanted to keep his hands clean. Maybe the flush machines have better features now, these occurrences happened about 5 yrs back. Filters are still sold and changed out and still serve the same purpose they always have, just takes more time and uniforms and hands can get dirty during the process. btw, ASE certified grease-monkey here...A1, A5, A6 and A7 ;)

I changed the fluid in a 1995 Saturn once, they used a spin on oil filter! There was even a doughnut shaped magnet on the tranny to catch metal debris.
BTW, in the Saturn owner's manual it tells you HOW to do the procedure yourself.
No mention of flushing out the trannny either.
Also, I've heard that the dirt build up in an older tranny may actually seal up leaks and flushing the tranny could actually create leaks.
Is there even a changable filter in the Yaris A/T?

Apparently so. A quick check showed PNs from Fram & Wix
