I have a 2017 Escape 1.5 L AWD and I'm due for a transmission service.
Here in is the problem. My owners manual states "drain & fill", Replace the same amount as drained out (4-5 liters).
I know Scotty doesn't recommend a "trans flush" but is this the same as a "fluid exchange"?
I of course want to get as much of the old fluid out as possible, so do I drain and fill, or fluid exchange? I'm confused by these terms.
Thanks: Dave {black}:amazed:
Please follow every posting instruction. It's not there for fun. We need the mileage to provide accurate answers to your question. Thanks.
That way I've always used the term is that a "flush" uses an external pump to force the old fluid out and pull new fluid in. This has the potential to cause internal transmission problems due to excess pressure.
On the other hand, a fluid exchange uses the transmission's own internal pump to change the fluid. Transmission internals are not subject to any unusual pressure this way.
Both of the above are done by tapping into the transmission cooler lines. (Obviously not possible with an air-cooled automatic transmission.)
Drain & fill means manually draining the fluid from the transmission pan much as you would do for an engine oil change. This has the least potential impact on the transmission but not all of the fluid is changed because a large amount stays in the torque converter. (Some automatic transmissions have had torque converter drain plugs but most do not.)
Good to know.
TMK, fluid exchange is synonymous with drain & fill.
uhhh no. You ought to try this thing called a web search.

Hahahahhaha.
I’d like to hear others thoughts.

Transmission flush is something different than this.

You should follow the manual.

These are just worthless marketing words. They have no basis in reality. What really matters is what the guy with the wrench is going to do to your transmission. Talk to the guy with the wrench.

If you don't abuse the transmission, and keep on top of maintenance, then it doesn't matter. You don't need to get it all.
How many miles do you have? Have been maintaining it regularly? Has the transmission shown any problems? What is the condition of the fluid right now? These are the question you should be asking yourself.
Plus, this has been discussed endlessly here. You should check the FAQ, and use the search before asking old questions again and again.
