I cant agree more with Howard.... Do Not Mix F and Dextron, totally different properties and they do hold different shift characteristics..i.e. Dextron shifts noticeably smoother than F.

I warranty Transmissions running either fluid but I do tend to lean towards Dextron and very happy with its performance.

IF you do drain, dont forget to drain the Converter as well. Drain the brass plug, turn 180 and drain the other plug.
