Changing ATF fluid

[David Torrey]

Audi Listers -

I replaced ATF fluid with Amsoil  synthetic in my '93 100CSQ Avant at 40K
miles.  I am now changing again  at 120K miles.

My question is whether or not to change the strainer attached to the valve
body before I refill. This means removing the ATF oil pan.  The Bentley
manual has a procedure for cleaning oil lines going to the  oil cooler with
compressed air,  but makes no mention of replacing the strainer after x
number of miles.  Anyone have an opinion about this ?

Best Regards
