Transmission Flush/Change?
after reading this post, i went to check the trans fluid level on my gs400 and found it to be low. i'm not due for a trans fluid service yet, but i want to add fluid... but where does it go?

what do i do if i overfill? will i have to syringe from the dipstick tube?
I'm a bit confused. Some wrote that a drain & fill is about 2qts....then there are others that mentioned 4qts? So how much is it when you do a drain & fill?
How many drains & fills does it take to get rid of the old stuff and have the new stuff in there?
I currently have OEM ATF fluid in there. Would it be ok to mix OEM & Amsoil fluid? I really don't want to flush. I rather do drain & fills.
Thx!

4 or 5 drain/fills will get a good percentege of new fluid in there, however, it will never be 100%, it just keeps halfing itself
(stand 4 feet from a wall and keep taking a step half the way there, 2 feet, 1 foot, 6", 3", 1.5", .75", .375", .1875", .09375", so on and so forth... by about the 5th step you're as close as you need to be, but technically you'll never get there)

Too bad no Amsoil here.

One final question. If I can't get my hands on Amsoil products, would Mobil 1 Synthetic ATF be ok? http://www.mobiloil.com/USA-English/...hetic_ATF.aspx

I actually use Mobil 1 ATF in my PSF, great stuff and widely used as PSF in a lot of vehicles apart from Lexus.

Mobil does have one though, ATF 3309
it is compatible with Toyota T-IV, whereas normal Mobil ATF is not...
Maybe the the Mobil ATF3309 fluid isn't synthetic???
