Tranny fluid disappearing

1991 Mazda B2600i pickup, automatic. Uses 1 qt. fluid per 200 miles. Absolutely no drips on concrete carport. Bottom of tranny dry. Where is the fluid going? All help appreciated. Ivan Vegvary

It MAY have a vacuum modulator with a perforated diaphragm which can cause fluid to get ingested by manifold vacuum.

Looks like it does have a vacuum modulator. Disconnect the vacuum line and check; ANY fluid indicates an issue.
