Changing Transmission Fluid soon...should I change any other fluids too?

I've been noticing my transmission is shifting a little jerkier in the low gears. My transmission dip stick reads a bit low and the color is that dark amber/wine red color. Might be time to change.

Got the car at 56k miles, now 13k miles later it's only had A1 and B1 service but I thought I might as well change it now, regardless of MID. Main question is, should I change the transfer case fluid as well? And even the rear differential fluid? Or should I just change the rear diff fluid when MID advises me to? Thanks in advance everyone!

Will do sir! Guess I won't be following the MID for those changes anymore. Slight bummer.

My A123 (oil, transimisison, transfer case) came up at around 50k miles. Rear differential (item 6) came a little bit earlier.
Maybe your previous owner didn't following the MID?
If you bought the car used it is always a good idea to change all fluids.
However I bought the car new and now at 80k miles I never see (item 5 coolant) come up. Not sure if MID is just wrong on this one. Maybe I should change it soon to be safe.

My 13' TL FWD just hit 5 years and 55k miles. I got the usual oil change but I also got the transmission fluid and brake fluid changed for the first time. I'm too lazy to ever look at my fluids but I can feel the auto tranny is definitely smoother going from park to drive, whereas before it could be a little jerky at times. I also switched to full synthetic on the oil change, not sure if that really matters.
I'm trying to go by the service manual so next oil change I'll probably get the power steering fluid and coolant changed.
Since I'm out of warranty I'm not going to Acura for service anymore, I found a very good local shop with reasonable prices.
BTW, last time I went to Acura, they told me my brakes were shot and I needed new everything.
I took it to these guys for a second opinion and they physically showed me exactly how much pad I had left, 8mm front and 6mm rear. Everything looked perfect.
I may never go to a dealer again for any type of service other than warranty.

Thank you for the information! I generally only go to the dealer to get fluids I need when working on the car. Other than that I stay far away. Although dealerships generally do the best work and are specialize in working on whatever brand it is, they always felt like it's a premium service. Always try to find a trustworthy local mechanic that gives fair prices or even better, attempt to learn maintenance steps yourself.

Carfax reported a lot of trips to the dealer but you're right. I should have done everything once I got the car. I was just too excited to drive it than anything lol.

Yeah, while you're changing the transmission fluid, go ahead and change the transmission fluid. After that go ahead and change the transmission fluid

No really, I'd recommend a 3x3 "flush" which consists of doing three drain and refills of the ATF, usually putting a few miles on the car in between to mix everything around. A lot of guys on here will do that if they purchase a used Acura to get new fluid in the transmission. You shouldn't do any sort of power flush on a Honda or Acura transmission but doing the 3x3 replaces a good portion of the fluid which will help more than doing just a single drain and refill.

With the 4G, you can actually get about 3.5 quarts out; even 4 quarts if you give it a few hours to drain. With three 4qt drains and refills in a 10 quart capacity transmission, you'd end up replacing 78% of the fluid. 40% of the fluid the first time, 24% the 2nd time and 14% the third time.

Don't forget the brake fluid, if it hasn't already been done have it changed.

I have a 2013 Acura with 62k still on original brake fluid. Never changed brake fluid on any of my previous cars. What is the importance of getting it drained and refilled?

Because brake fluid absorbs moisture, which can lead to brake failure.

Moisture from your brake fluid can cause failure | Northwest Herald

From that article:

Your brake fluid will accumulate moisture over time. In fact, according to a report by the National Highway Traffic Safety Administration, 20 percent of the cars it tested had brake fluid with 5 percent moisture content. 3 percent moisture content in DOT 3 brake fluid reduces the boiling point of the fluid by more than 100 degrees.

“When the moisture in the brake fluid boils because of the tremendous amount of heat generated by the brakes, you can actually lose the ability to stop,” McAllister said. “Plus, moisture can cause corrosion of the wheel cylinders or brake calipers and eventually cause a leak.”

So basically that would be an entire system flush like the dealer has been trying to pursue me to do. Guess Iíll take care of that as soon as possible.

Rule of thumb, always do a flush on brake systems, never do a flush on automatic transmissions.

Dealer tried pushing the Transmission flush on my car but I told them to only drain and fill the transmission. Donít know if the dealers actually flush the system or if itís just a drain and fill.

I typically get about 60k miles out of brake fluid (my mechanic bases his recommendations on fluid discoloration, not mileage) If you drive a lot of highway miles without using the brakes much, that'll happen.

But most manufacturers will tell you 30k at most between brake fluid changes. Which, if you drive your TL like I don't, is probably too long.

Here's a recent photo of me:

There isn't a single vehicle manufacturer (or competent mechanic) in the world which makes a mileage based recommendation on when to replace brake fluid. The fact is, brake fluid is utterly and completely unaffected by mileage, however, time is a different story; whether you drive one mile or one-hundred-thousand miles per year, brake fluid will degrade at the same rate per unit of time.
