Re: Synthetic ATF: need advice

[Avi <Avi@cosmoslink.net>]

I am currently using Mobil 1 ATF on my 86 5K turbo about 5,000 miles, so
far no problem and no more leaks than before, the Mobil 1 will mix OK with
the std. ATF so no need to suck it all out (of course it would not hurt),
there is only a strainer, no filter.
If you change the ATF via draining the transmission remember that you are
only changing about 33% of the ATF, the rest remains in the torque converter.
