I changed the tranny fluid (and filter) last weekend with 8 liters of Dr. Z's secret profit formula. The old fluid was dark, as expected, but there was nothing unusual in the pan - not bad for 95K.

Now I notice that the up- or downshift from second to third is clunky, and the downshift to second causes a noticeable drop in RPM when slowing to a stop, as if this might eventually cause a stalling problem. Maybe it's staying in third too long, and then finally clunking hard into second when it realizes it better move along.

Any alternatives to visiting one of Dr. Z's US henchmen, who will automatically overcharge me as step 1 of their diagnostic procedure?

Thanks,
Tom
