Change automatic transmission fluid?

sergeyv said:
Hi there. My CX5 2012 has 110000km and I bought it at 105000. I don't think transmission fluid has been ever changed on this car and I don't believe in lifetime fluid either. Should I just drain and refill like most here are writing, or remove the pan and replace the filter too?

I agree with Conrad 16.5 and Id do the same - drop the pan and change the filter cartridge. Further, I may even consider doing it twice like this video showed: do ATF drain-and-fill for the 1st round, and after a week or two drop the pan to replace the cartridge for the 2nd round.


And this thread is very informative for DIYers:

So I'm not too late for the metal shavings to be there yet?

Nobody can guarantee you anything. We can only say your transmission is approaching 68,750 miles and the better bet at this stage is doing the ATF and filter cartridge change if you want to keep your CX-5 for another 50,000 miles. Follow the video and use Mazda genuine ATF FZ, and most likely your transmission will be fine.
 
Permatex High-Temp Red RTV Silicone Gasket Maker is ok for the gasket or should I use the Permatex Ultra Grey RTV Silicone Gasket Maker - Rigid High Torque I already have?

Although Permatex High-Temp Red RTV Silicone Gasket Maker has higher temperature range, but based on specs of application I probably choose Permatex Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker as it does mention automatic transmission pans in Suggested Applications but not on the other.

I would try to find one with a silicon gasket as well... Good to see these options show up as it makes the job a lot easier. You can do it in one day instead of having to deal with cure time for the RTV.

Thankd for the info. With ready-to-use pan gasket the job should be a lot easier and more consistent for not leaking at the first application than applying the silicon gasket. But from my past experience those cork gaskets for automatic transmission pan would start to leak eventually, not as reliable as the silicon gasket.
 
WAIT -- it's the same company - do NOT use it. I had used the exact same thing but for 2007 Toyota Corolla. After 3 months thankfully in my garage found blood all over ...... only to realize its transmission fluid!

The gasket is made of some type of hard material which was crumbling when I dropped the pan again. I believe its due to high temp.
 
I wonder if a few kits out there?

Official instructions do not say anything regarding the filter replacement and sump removal. Bummer. Called mazda today to order oil and filter and they told that if I drain the oil from the sump and replace the filter, that'd be only 3.5 litres of oil. If I do the flush with the mazda, they do it with special machine and they put in 10 litres??? That's a lot. And moreover, they don't drop the sump and don't replace the filter when flushing.

I once stood at the parts counter of a Toyota Main Agent trying to buy brake fluid for a vehicle still under warranty. The guy there appeared with the equivalent of your 8oz bottle. I asked for another bottle and ended up in an almost heated discussion about whether I needed one. I tried to explain that the bottle in front of me was hardly enough to replenish the reservoir and his response was, well thats all we use and it wasnt necessary to completely flush the whole system.

The point Im coming to is that even Mazda themselves are capable of dishing out suspect information. Whether its errors in sales brochures or as in this case, stabbing at info theyve gleaned from the many service publications that cover the range. The information I trust are the technical papers that originate from the design offices in Japan.

Above in the service pdf, it says that you can get up to 4.9 litres into a refill and the attached pdf says that the factory capacity to fill an empty transmission is 8 litres, neither of which correspond with the info you got. Maybe they flush with 10 litres and sacrifice a couple of litres. I guess because the filter requires the removal of the pan, they dont believe there is any benefit in changing the filter. They will have tested transmissions in development that have done astronomical mileages and should have the details that generate the service info. Most Toyota transmissions are sealed for life. It seems to be the way they are going and of course, gearboxes will eventually become motors.
