What maintenance should I do 2012 SH-AWD auto
 

I was just sort of thinking about what maintenance I should be doing to my TL. I think im good for everything except for possibly changing the rear diff fluid. I bought this car from auction and it came from another province so it was kind of a gamble but I managed to get its service records. Remember all numbers are in kilometers not miles. The rear diff fluid was last changed at 81,184 KM. The car currently has 107,700KM. So im wondering if anyone can suggest when I should get this done? Or any other maintenance I should be doing to it. It has all recalls done and since I got it ive changed oil and filter, the transmission software update was done by the dealership which included changing the tranny fluid, and it got 4 new rotors and 4 new brake pads. For reference these are pics of some of the records I got. The KMs at the top right of the second pic I was told must have been a typo and the third pic shows when the rear diff was last serviced 06/03/2015.... I could only get it in French since the dealer it was done at is in Quebec. Any advice would be much appreciated.

Can a mod please delete this thread so I can repost an edited version? Thanks!

I would perform a brake fluid flush and change the rear differential fluid. The brake fluid flush is due every 3 years and the rear differential is due at 15k miles (~24k km). I would also look at a drain and fill on the transfer case fluid which is typically due around 60k miles (~96k km), typically the ATF fluid is changed as well but it looks like you did that already.

Thanks for the info I will defiantly look into having these things done. The third page that I posted which is in French says they did the transfer case fluid on 11/30/2015 / 96,271KM which is spot on the 96k km you said. So it looks like I only need to do rear diff fluid change and brake fluid flush.

Heck I overkill just about ever oil change I do a replacement of rear diff - after I read a story about the fluid and ability on sheering forces. I do transmission yearly and transaxle every 2 years. Overkill

Hi. I'll be doing all three (ATF, rear diff, transfer case) in the next week or so. I bought my car used and I'm wondering if my '14 TL SH-AWD 6AT is missing the front passenger-side undertray as referenced in the acurazine how-to (link below).

Do you all have this? Any idea where I could buy a replacement? I know it's probably not a huge thing if it's not there, but I'd rather have it. I've checked some OEM acura parts stores online, but no luck so far.

Thanks in advance.
