oil pans don't rust
I guess I'm in a different world or sumthin.

It does seem kinda counter-intuitive. I mean, it's literally full of lubricant.

When my buddy's RAM oil pan rusted through I made fun of him because I thought only Dodge could make a pan full of oil that rusts through....but the last time I was under my wife's Mazda I realized it's getting there, and will need replaced sooner or later. I guess my Chevys have always just leaked enough oil down the outsides that it keeps all that stuff from rusting .

^^^^^^^^^^^^^^^
Or the issue folks run into with the Tundra in removing the pan is that the bolt holes are open on the top of the transmission so all the mud and crap gets down into the threads of the bolts and it’s pretty easy to snap trans pan bolts. Which creates a bigger issue.

Lifetime fluid, not in my lifetime. Our 2019 C7 with 25,000 miles needed new fluid. The local GM dealer said we were lucky that’s all it needed as they had a backlog of 52 transmissions that needed replacing.

I don’t understand how an Explorer drains most of the fluid. My Odyssey and F350 only drain half and the rest is in the torque converter. I do three drains and fills to wind up with 87.5% new fluid.

It doesn’t I got about 4.5 quarts which is a little over 1/3 of the fluid.
As easy as it is on this thing just do a drain and fill every 30k miles and you’re good. Or like you do 3 or 4 fills in quick succession and go longer on the mileage.

.

They have the threads open for when they used RTV for a gasket from the factory, didn't want the bolts hydro locking with RTV in a closed bolt hole.
Not sure if they went back to gaskets from the factory, haven't seen anything that new.

Totally agree. My 2009 Corolla still has a drain plug and a dipstick. Also crank windows.

DCTs for me. No hydraulic fluid.

It may not be hydraulic fluid, but it still needs lubricating oil in the gears, and also the clutches if they're of the "wet" type. (Most DCTs I'm aware of use dry clutches.)

^^^^
I don’t expect that the DCT of my Genesis G70 will need service while I own it.

Boy are you right about this!!! I watch the Care Care Nut on YouTube. He's a Master Tech who specializes in Toyota and Lexus. He says if you haven't had the fluid changed every 30,000 miles and you reach 100,000...LEAVE IT ALONE!!!! Other You Tubers say it can be changed and if it begins having problems after a change, it was on the way out anyway. Most agree that a drain and fill should be done on a high mileage car, not a flush. Differing opinions....

My fricking Volvo doesn't even have an engine oil lipstick. I looked retarded searching under the hood, even had a flashlight.

I was in his shop this week and that’s exactly what he told me in regards to my 2013 Corolla. I was wondering about doing a partial drain and fill. He told me to leave it alone. Said I have a better chance of increasing the longevity of the trans by not doing anything.

One of the few things that aggravates me about my new Jeep is its 8 speed transmission. It shifts 3 times before the end of the driveway! 8 speeds is 3 too many! This and auto start/stop are the epitome stupid automotive ideas!

Wait until that one needs servicing.
