1. At 51,600 Miles, without any previous AT service, YOU NEED TO CHANGE YOUR FLUID AND FILTER NOW!!

2. I don't care about anyone who says they drove their Mazda for 4Million miles without an AT Fluid Change. You need to change your AT Fluid
and Filter NOW!!

3. Whether you want to spring for a full PROFESSIONAL SERVICE FLUSH or just change the Fluid and Filter is your call. If you have the money to do the full Flush,
do it. But you are not going to do it yourself because you need the Adaptor Plate to do it or it won't work.

4. Perhaps contradicting my friend, Callisto, who knows 1000x what I know, changing the fluid and filter is better than doing nothing. Maybe not as good as the flush but better than doing
nothing. On the Mazda 247 site there are many debates about this and plenty of people JUST drain the fluid, no filter, and others drain the fluid AND change the filter. Flushing is not discussed much if at all. But, again, all respects to Callisto.

5. I am going to address another piece of bullsh_t: That when you drop the pan and drain the fluid, you are only draining a tiny bit of the ATF fluid because such huge quantities of fluid are trapped in the Torque Converter and Valve Body, etc. It is NOT a tiny bit of the fluid that drains. I did this on my Toyota Sienna and on my Chevy Cobalt (Sienna for 20 Years) and after dropping the Pan and draining the fluid, changing the filter, putting it back together, the fluid on the dipstick was perfectly pink until the next service. Perfectly pink. Now that would be impossible if you were only draining 20%, 30% of the fluid. So, the people who say that are so full of sh_t that if you look at their eyes, you can see the brown reading midway in their eyeballs like reading a dipstick. OK? You are not draining 100%, but you also not draining 20%-30%.

This is the truth. do not ask again whether you need to drain fluid and change filter, you do. If you don't want to, then don't, but don't ask again.

Callisto, your turn. Best, Reuben

If you abuse your body, eat 5 lbs of pig lard a day, take huge doses of methamphetamines, etc. you might not drop dead at 23 Years of age.

But you won't be running marathons at 65. Do you see the point? Of course you don't have problems now. The problems will be when you

hit 100K, or 150K, or 200K, and lose the transmission. At 50K the Car is practically brand new!

Call back and ask them if they have one my guess is NO! Why the better ones start at about $3500.00 and requier that someone be trained to do the service correctly.
So naturally they are going to tell you it's not needed or maybe other reason why NOT to have it done!
Sierra College in Rocklin CA auto Shop has one of the only existing Transmission Dynameters in the nation at a college or any school even for Automotive mechanical institutions. the professor would often let me use it to test transmission and some of my builds when I was professionally Racing in NHRA. Even in the 80's and on to the 20's he stressed the importance of fluid Changning and complete fluid replacement to prolong the life of automatic transmission and to prevent their slow decline. What he often says in his class is that same thing I keep saying here on this forum that although many have become accustomed to not servicing an automatic transmission and not the antimanufacturing supporting that there is no need to change the fluid we all think it is ok. It's not. And the first time you are having to pay for a new transmission that can be determined was failure either completely or supported by not servicing it you will be on threads like this and suggesting doing more frequent filter and pan fluid changes and considering a complete properly serviced fluid replacement at no more than 50k miles.
Anyone that has over 50miles on their transmission can get an oil analysis and post up the information and let's see how many of your transmission are in the good shape you think they are?
In the meantime, go look what a replacement transmission cost installed.



Or hey what is better is keep looking on the internet for the answer you want to read.... LOL

I do not believe in lifetime transmission (with no service). Transmissions run hot and fluid turns into varnish. I guess when they say lifetime it means drive until it dies.

P.s.Main reason in this topic for me was like could the refilling transmission fluid harm the transmission or not,because i'm not a specialist in that kind of things but lucky me i found that forum and couple of friendly users which told me that it's necessary at least to do drain,refillings and filter replacement and that will prolong the life of transmission.
P.p.s.Unfortunately you wasn't from this list of few friendly and informative users and told only about laboratory analysis and wrote many LOLs
