This on behalf of a friend who has an '84 5k automatic and no E-mail address: Someone recently posted here to the effect that Audi's maintenance schedule doesn't say anything about changing ATF, ever, and this could have something to do w/the prevalence of 5k's w/blown transmissions in junk yards. So, how often <should> ATF be changed? Thanks. --Andrew Buc, Seattle, WA; 21-Sep-97, 11:09
