Yes, that is what I did... Tranny then shifted nice and smooth...
After that procedure I have used a hand pump fluid extractor to pull a quart at a time of additional tranny fluid out from the dip stick tube and replaced the extracted fluid with fresh Dexron VI... I have done that about a quart at a time, each weekend for 3 times now... I'll do that a few more times so that I have a high percentage of clean Dexron VI in the tranny...
