When I had my 2008 Chevy it had the spin on filter which was nice. My 2020 GMC with the 10 speed transmission does not have a dipstick or any place to check the ATF. It is a closed system that I will probably have to take to the dealer to have the ATF changed.

You simply just don’t give up, do ya?

For any interested AS69RC owners......a “complete” exchange is not necessary, basically for a couple of reasons.

First....the service manual does not specify that a “complete” exchange is required.

Second.....my previous 2014 RAM 3500 with AS69RC made it to 362k miles with the transmission maintenance being performed basically by the book. Guess what? My current 2018 RAM 4500 with AS69RC is at 357k miles, and is doing great with the same maintenance by the book.

Sure...I may have been over on a few drain and fills by three or four thousand miles, and perhaps a sump filter change by a similar amount, but the 2014 and 2018 have been superb.

Finally a breath of fresh air.[emoticon] Same with my 68RFE , no interest in a complete fluid change. Stupid me [emoticon]

GS nice to see you here. I am sure you have missed me on the TDR as my suspension won't be up until August 15th. This thread is nearly two months old, you must be bored.

I stand by my statements saying if possible ALL your transmission fluid should be changed. So far I have not figured out how to do so on the AISIN.

Maybe explain if the AISIN is perfect with partial changes WHY you added a deeper pan to allow for more trans fluid on your truck??? Not criticizing you for doing so because that's what you wanted to do.

2014, it's really simple to do a fluid exchange on the 68, why would you not do it???

It's simple for me, what's the benefit ? Haven't heard of a reason yet, other then do it from you . I can't remember if I have ever heard anyone besides you say to do a complete fluid change on a 68RFE. Pretty sure if I have someone do it ,dealer or otherwise its going to be drop the pan, change the filters ,and refill. If not mistaken that's the recommended way.

2015 user guide simply says "Change automatic transmission fluid" or "Change automatic transmission fluid and filter(s)" then goes on to give intervals.

I see nowhere partial fluid change. Common sense tells me it's better to change "ALL" fluid if possible.

People do what you want and I shall also. Funny how it rubs some the wrong way when I suggest changing all if possible.

Yes, you’re right, and yes you’re wrong…
I too prefer the fluid replacement method getting all or nearly all the fluid out and replaced at once. However that is not how the maint intervals are called for on the Aisin. It’s basically half the fluid each time.
Maybe no coincidence that the intervals seem about 2x as frequent as they would seem to be.

My wife’s 2005 Acura MDX called for a transmission service that entailed draining the transmission, filling, driving, and then repeating 2 additional times for a transfer of 9 litres. I simply drained the transmission every second oil change and refilled (3 litres each time) and the fluid was like new right up until we sold it this past spring. So for the Ram I would do the simple drain and refill as per the book (or more often if it makes you feel better) and call it good.

And it’s very easy to get a full drain and refill on my G56 manual truck! [emoticon]
