I have a 2011 GSR with 66k miles on it. I’ve been religiously changing oil every 3-5k miles but other than motor oil I have never serviced the car fluids wise. I know it’s definitely time to do transmission oil but what else does everyone recommend ??

Trans, diff, AYC fluids.. I would do spark plugs too and replace the fuel pump relays if you haven't been doing that. I would honestly recommend changing these closer to 15k-20k instead of 60k. That's a long time.

Other stuff you could look in to is swapping the brake fluid and coolant out with some fresh fluids too.

 

thank you so much this is great. My AYC pump failed a little over a year ago and was still covered under that extended warranty and the dealer replaced it so I’m probably good on that. Otherwise this was big help thank you

 

Still need to do it. As far as I understand, this is those are two separate things. But everything in that link should take care of you.
