Yeah I know, lifetime fluid blah blah blah. I still don't buy that it's anything beyond "lifetime of the warranty" fluid. Has anyone actually tried draining and filling theirs yet?
According to this:
there's a drain plug and elsewhere I've seen there's a fill/level check hole into which one inserts a dipstick tool to check the level.
I think it only holds 6-ish quarts... if say, 3 came out the drain plug it'd be worth doing once in while if you ask me. Drain, measure what comes out, put that much back in, check the level, adjust.
"How hard could it be?"
Actually you are correct that there is no such thing as lifetime fluid.
But with normal use, that is no towing or serious off road usage, 120,000 miles might be the lifetime limit in my opinion.
I tow and will probably change it out at 50-60k to be safe. The dealer will do that change for me. Several considerations you need to consider.
*Its a sealed transmission and you have one shot to get the level correct. That is not over or under filled at the correct temperature.
Its not like you have a dip stick to easily pull out and check. There is also a way to check it but you need a special tool which you may want to invest in.
Desoto's tip is a good one also.
*Also you must be careful not to introduce any contaminants.
*You also need a specific
fluid which is not necessarily inexpensive.
*There is also a filter that needs to be changed when changing the fluid I believe. There may be other things that need to be done also.
* u-tube video may help as it does show you how to check it and what tool you need:
If you know what you are doing and are confident, I imagine its pretty easy. But for me I'll let the dealer handle it as its not quite like an oil change.
