Just finished installing 700r4 tranny from a GTA into an IROC shifts fine ,lots of pull .However now when checking level ,fluid is kinda like a pink milk shake a small hint of milky white color .Suspect some water mixed in with old tranny oil which was a nice lite red color .My Q is will this water evaporate when tranny is heated up from running or is another flush needed ? THANKS

 

FLUSH!!!!!!!!
