Hello,

I bought my 2007 in 2015 with 100K miles. Now in 2021 she has 150K miles and I'd like to change the transmission fluid. I bought the car at Carmax but not sure what they did to the car before selling it.

The color is a medium reddish brown(not black) and there's no burnt smell, so wondering if it was changed sometime before I bought it? Transmission works well, no issues so far. Just afraid about what I've read regarding changing the fluid with high miles and having tranny issues afterwards. Appreciate any thoughts you have. Thanks

Thanks Spector and Slimm, good info. That's exactly what I needed to know.

5 yrs. later & 50K miles, the "brownish" color indicates the fluid is beginning to oxidize. I would go slowly on the fluid changes as you don't want to introduce to much newer fluid (you don't want the "detergents" to dislodge to much crud @ one time as it may clog the passageways). I would drive a few hundred miles between ea. change. 44/66/83/92% is what ea. d/f will give you new fluid wise (dilution). You may want to change the inline trans. filter on the last d/f.

Good info KW..... when I do the change, guessing I should only refill with exactly the same amount that drained out? Thanks again!
