What is the deal with Transmission fluid changes?
|
|

I have been searching the web trying to figure out what is the best approach with transmission fluid flushes. I cannot find a consistent answer. There seems to be a real divide in the automotive world about this matter. I made a survey to try to find an answer. Here is the link

I would really appreciate some help.
Thanks!
My car is a Chrysler Town & Country, 2008...but I will just like to have an overall understanding at this point.

Flushing shouldn't be necessary if you change your fluid and filter as per manufacture recommendation. Fluid and filter change is recommended every 60 K miles under normal conditions.
If you have your heart set out for flushing, that doesn't mean you don't need to change your filter. If you flush, you should change your filter, fill the transmission with clean fluid, and then flush. Don't put any chemicals in before or after a flush. In fact no chemicals whatsoever should be put into the transmission other than transmission fluid unless specified by the manufacture.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Let me add a differing opinion.
I see no need to ever drop a pan and change a filter that is usually no more than a screen anyway. I think the word "flush" is just misused in the case. The machine is just a total fluid replacement tool. It helps you replace all of the fluid rather than the approximately 1/3 that will be removed by removing the pan.
I agree that additives should not be used, just complete replacement of factory approved fluid. If the filter gets clogged, then it's already too late for that transmission.

There will be clutch material and planetary/differential gear metal in the bottom of the pan and caught up in the filter media as the transmission is being used. Plus dropping the pan is a good idea when servicing the fluid because you can tell the state of health of your transmission by looking at what is laying in the bottom of the pan and stuck to the magnet.

I think complete, timely fluid changes would avoid all of that.
