First, I apologize if i missed a previous thread, every one I read was confusing.

1. What is the interval to change the transmission fluid?
2. Is it worth doing yourself? I have read that it is a bit difficult.
3. Anyone know how much it would be for a 3rd party to do it?

If you do a drain and fill, do you not replace the filter?

According to the owners manual severe schedule 50k mi normal schedule 100k. Drain and refill 9.5qts, drain plug is on the bottom and there doesn't appear to be a user accessible transmission filter.

Drain and fill is easy. Plug is on the bottom. Exactly 5 Quarts will drain ( assuming you were filled to the correct capacity to start with.. You will not get it all out, but 5 is better then none. I did 2 drain and refill ( 4 months apart ) , search the posts. If I find the link I will post it. You cannot get to any filter unfortunately, its internal in the transmission and is NOT accessible. My fluid was extremely dark at 20K. Literally will take you 20 min to do the partial drain and fill easier and cleaner than an oil change.

If you're planning to keep the car, for the bit of extra cost, it might be worth having the dealer power flush the entire system.

Never let a dealer "flush" a transmission. GM recommends only a drain and refill, never a flush.

Nothing wrong with a transmission fluid flush. Most transmission flush machines don’t really flush or power flush, they just hook up to the transmission cooler lines and let the transmission’s pump change or exchange out the old fluid and simultaneously pump in new fluid. In the end, you end up changing more fluid out, including what is trapped inside the torque converter.

Can you give us a reference as to why "never flush"?

Agree, X2; a flush will insure all the old fluid is removed and replaced with new. I've done them for fifty years and never been given any valid reason for not doing a complete fluid exchange.

You don't know what your getting. If the equipment is not meticulously maintained, it can introduce contaminants into the system. I would rather not take a chance.

Most machines keep the clean and dirty fluids separate. No chance to contaminate your car with contaminated fluid from another car. Contamination from a transmission fluid machine is a nonexistent issue.

You can still dislodgel particles trapped in the filter which would then circulate throughout and clog small passages. I, for one would not risk it, especially since it is not necessary and GM does not recommend it.

The filter would require separating the trans and engine I believe so not easily changed. I too would just recommend draining and filling, month later do it again. If you repeat that process a few times you will get most of the old stuff out.

"Most machines" and "nonexistent issue" are contradictory.....

I should have said All transmission service machines keep the dirty and clean fluid separate. No shop would use a machine that did not because it wouldn’t make any sense to.

Exactly what I did. At 20K, fluid was dark brown, not cherry red. I did 2 Drain / Fills 3 months apart, will do a third once the weather warms up in NY. It is exactly 5 Quarts with the Drain and fill. Easier and cleaner than a Oil and Filter change!

My 2010 SRX 3.0 has 106000 miles on it and recently the last 9 months started with shifting problems. Going into 2nd gear and then abruptly dropping back down to 1st. Was told by a local transmission shop ( beware of some of these guys ) that I needed a new transmission control module. This would cost me $1900 dollars. Problem is once the tranny warms up the shifting problem goes away! Takes about 5 minutes to reach operating temp. SO I decide to drain and fill with fresh fluid. Did this twice one month apart. Shifting problem GONE! Point is a $30 drain and fill solved my problem and saved me $1870 dollars. Won't work for everyone I know but this tranny shop could have suggested the same but like used car dealers not always so honest.

I changed our 2011’s at 45k and just today at 88k - drain and fill. It’s about 4.5 qts. Clean fluids are always good. Don’t overthink it and just do it. It takes more time to clean up than to drain and refill.

Hello all, I no longer have my 15 SRX traded for XT5. But I wanted to share the following for what it is worth...

I did a total of (4) Drain and Fills. about 3 months apart from each other. The car only had 22K on it. The fluid on the first change was amazingly dark. I used a clear cup to do a sample before each change and I snapped a photo holding it up to a light. You would think that 15 quarts total in 9 months, the final sample would be noticeably lighter in color (Cherry Red) well..... No. Absolutely no VISUAL difference. The reason I say VISUAL is I am sure there are some benefits with the cleaners etc. in the fluid, but without seeing the visual change, I personally would not recommend you waste your money on the above. I did the homework and VISUALLY saw NO noticeable difference.

I was quite surprised to see it be so dark with what I consider such low millage. Since you cannot do the filter because of the transmission design, I would recommend a FULL FLUID CHANGE. I wont get into the semantics of Power Flush etc. but would highly recommend a FULL FLUID SWAP. There must be a lot going on in this transmission design to get the fluid so dark so soon. Find a reputable dealer or shop. The drain and fill is only partial and I understand that, but noticeably NO VISUAL DIFFERENCE.


I noticed the post by roswell1952, I experienced a similar problem on my 2014. It was low on fluid in my case, and had nothing to do with partial fluid swap. It does not state if the fluid was checked prior to the partial drain and fill.

I would recommend that SRX owners do the following.


1. Professionally swap ALL transmission Fluid.

2. Do a suction out (by any means possible) of Power Steering Fluid and fill with Fresh Transmission fluid (OEM) or quality PS Fluid.


3. Full Drain and Refill of Radiator Fluid every 3 to 4 years,


4. Power Bleed your Brakes. Simple procedure with MOTIVE system. Takes about 30 to 45 minutes max. For sure a shady tree mechanic job. Recommend every 3 to 4 years. I personally do every 2 to 3.

I do have a mild case of OCD, but I do like to do the above. Keeps my OCD in check....

Positive / negative comments welcome.

I'm planning to do mine soon. I'm an Amsoil Preferred customer and I change all my oils to synthetic soon after purchasing a used vehicle. I'll be changing trans fluid(100%), power steering fluid, engine oil and brake fluid.

I did it on my 2003 Silverado when I bought it used in 2007 w/160,000 miles. Now getting replaced by the SRX and now has 265,000...no repairs except brakes and electrical stuff.

Just something to consider.

Everyone gets so caught up in fluid color and the truth is modern transmission fluid turns from bright red to brownish-red relatively quickly and that does not indicate it is dirty or needs to be changed.

Try telling my OCD that.... Same with Oil.... Dark is particles... I appreciate the feedback and more than likely you are correct. That's what's great about these forums. But my OCD and I get along just fine after it looks nice and sparkly clean... Before every oil change, I dump in Snake Oil ( Sea Foam ) let her idle for 15 min. then do the drain and fill, heck I put the plug back in, wait additional 20 minutes, you will be amazed at how much more oil (dirty) drains out. Then I have some open unused oil, grade doesn't matter, I pour in a bit of it and wait till I see it come out of the Oil Pan drain hole, then she is ready for final fill. My OCD tells me that the tiny little oil valley's and orifices are free from varnish. When I look down the filler neck of any of my cars / vans it is pristine, no yellow or brown varnish look. Again, overkill and is more of a personal choice. Statistically I will probably not have the car long enough for all of the extra attention I give it and statistically the next person that owns it could care less.
But that's just me.
When I was a kid, my friend would change the oil in his GTO by opening the drain plug and letting the engine run until no more oil came out.:suspense: The engine survived.
