I'm deciding between doing a normal tranny flush: drain, fill, shift, repeat 3 times versus purchasing an Oil Boy to do the job.

Does anyone here know if the Oil Boy will remove all of the tranny fluid so that I don't have to mix high quality new tranny fluid with the old dirty fluid ? Thanks.

Does not seem to work that well, can't get it all out

 

damn I was hoping that the Oil Boy would be able to remove all the tranny fluid so I wont have to contaminate/waste expensive Redline. Oh well, thanks man for the insight.

 

I would only use Honda auto tranny fluid which is required in the manual unless I was outside the 100,000mile--7 year warranty extension. Why risk Acura questioning that issue on a $5000 part although they probably won't.
