3.6L 6 speed trans flush advice please

46181 Views 71 Replies 23 Participants Last post by  SilverSport
09 malibu 3.6L 6 speed with 50,000 miles on it. I was reading the owners maual and from what I understand the fluid is "lifetime" unless you fall under the severe duty catagory and then you need to change it at 50,000, is this correct?

I don't think I fall into the severe duty but I think I would like to change the fluid as a preventative maintenance thing, don't think it can hurt can it?

So if I do this do I need to flush it or can I drop the pan and drain and add new fluid? Also is there a servicable filter I need to change?

Any advice with this would be much appreciated,
Thanks,
Scott

"But: transmission fluid flushes? Uh uh. Flushes have been known to break crap loose that eventually clog a fluid filter, and fry the tranny."

I disagree with your comment. A tranny should not have any crap in it. If there is, it is already to late for the tranny. Most people follow mfg. suggested intervals for tranny maintenance which is mostly too late IMO. You need to check your oil often to see any discoloration and smell. If it si dark and smell gas, it is time to change it regardless of your mileage. I find Chevy's 50K interval too late. I believe this should be 30K.

I also have 05 Ford Escape, which is the easiest vehicle to work on it and I do my own flushes. I ve 85K on it and I've done 3 flushes so far.
