i met this elderly gent and while we were talkin trucks he was puting fuel in his newer 90's truck he took out a bottle of tranny fluid and put two capfuls in the tank,,,said it helped to keep things lubbed up,,,never tried it myself.
anybody else heard of this...this ol timer swore by it and said he never had to rebuild an engine .his cars and trucks fell apart first
