Thanks "FastBob", much appreciated. And yes, it is quite a rare and well kept specimen! Whoever had it before me certainly looked after it! I did have one before for nearly 15 years and that went was the Indicator Stalk! Sadly one day it just gave up and it would have proved uneconomical to repair. It was a 1998 (S). See below in its prime!
As to the Transmission Type, not a clue I'm afraid. All I know is that it is a 1.8vvt-i Engine and the car is a 2001 (Y).
I got the ATF Spec off Opie Oils, Fuchs ATF4400 being one of the choices and seeing as I have used Fuchs (ATF4134 ) in my CLK320 and it did the job, I chose that. I suppose it will be best to get the Filter from Toyota, unless someone can give me a pointer as to where else to get one...
Anyway, thanks again.
Regards, Bill.
