I had a '91 Westy with A/T. At about 100K I switched to Redline syn and the
difference was very noticeable, as was the switch to Mobil 1 syn in the
engine. The shifting was crisper, especially noticeable in cold conditions,
and a sort of whine it had, disappeared. I drove this as my daily driver for
over 2 years with the syn in it.
As far as I know, without considerable effort, the best you can do is empty
the tranny, change to a new screen and put in the syn. The amount of syn you
wind up with is significant enough to make a very big difference, even with
the mix of the remnant dino oil left. I'm not sure but I think there is a
little less than a quart left in there that you can't get to without opening
up the tranny and transaxle.
just my experience and $0.02

I like synthetics and have put Mobile 1 in my 91
without any problems. Now I am considering putting syn
ATF in my A/T, but want to query the list.
I read in the archives that some have put it in.
How to you get all the old ATF out? What are the net
gains if any?
