I changed my Transmission Fluid today on my 2017 RTL it had 31,400 mi on it. I'm attaching a couple pictures of the change and the one is quite surprising considering this vehicle only has 31,000 mi on it. The fluid doesn't look healthy to me at all. More like you'd see from a vehicle with higher mileage IMO. And since I've never had a Honda vehicle before this one I have none of those to compare to. So I'll rely on everyone here's judgement to see what yins' all think. I did take a sample for Blackstone labs to sample and get some results on the additive package wear in particular (asked specifically in the comments for that one on the return slip) so we will see what they have to say about the condition of the fluid at 30k miles. It will be interesting to see those results for sure since I've had them testing my Ford 1900 Tractor for a while. It looks to me like 30k fluid changes are a good idea though. And while 3.3 quarts is what everyone has been saying to put in I measured my removal oil at a little over 4 quarts. I ended putting in all 4 quarts! I will have to check again but it was at the lower mark.
