more questions -

If I am doing both pan drop / filter and flush , what is the recommended order ?


Is anyone draining the pan some by pumping out thought the dipstick tube or cooler line
to reduce the amount of ATF in the pan before removing it (less of a mess ) ?


Adding a bottle of Lubegard Red at the refill seems to make the ATF last a little longer . Many transmission shops use it when they install their rebuilds . It is not a magic fix or substitute for regular maintenance. Also, adding an inline filter ( such as the Magnafine available at Automatic Transmission Parts & Transmission Coolers, Makco Distributing ) is not a bad idea ( Webshots - Full Size Photo) either but remember that it has to be changed on a regular basis .

The shop I use drops tha pan, cleans the pan and replaces the filter, then flushes. The transmission has 231k mile on it and runs like a charm.

That' * what I wound up doing . It was amazing that there was hardly any residue in the on or metal on the manget . I must be doing it right with my gentle driving habits ,periodic flushes , and adding Lubegard Red at each flush . - Thanks
