Aisin transmission fluid change

[Ram4Sam]

Ineresting......here is the page from the 2016 diesel supplement.......just as the 2014 book says...... fluid every 30,000 and filter every 60,000.

Obviously a KOOOOK must have won the bid on the 2015 manuals. :-laf
Here's from my '14 manual....first edition.

Could we just get Trans Engineer to chime in and set us straight?....or anyone that has an FSM.

 

[Cummins12V98]

This is all for debate so it is interesting to see different schedules. I will be doing COMPLETE fluid exchange and filter every 30K. I think is is a good idea since I tow a combined 32,500#.

Seems more realistic but i don't see anywhere that any of these call for partial fluid change.

 

[gsbrockman]

So from that I would expect they wan the FLUID CHANGED not just part of it

Is the 68RFE service a partial fluid change???

I see no where that it mentions partial fluid change ANYWHERE for 68RFE of Aisin.

Where did this partial change come from? Documentation?

I see no where that it mentions a "FLUSH" or "EXCHANGE" or "100% fluid swap" for the transmission fluid ANYWHERE for the 68RFE or AS69RC.

Where does the "FLUSH" or "EXCHANGE" or "100% fluid swap" come from?

 

[kthaxton]

Does anyone have an FSM? I intend to buy one soon.....but.... it should have the procedure in it.

I think I mentioned it before...on all of the previous transmissions, transmission "service" consists of removing/draining pan, change filter, adjust bands and refill. In fact I know they would recommend against a flush unless the transmission had been flushed at all previous services since new.

I think it's pretty darn clear what I am doing. Now someone please SHOW me where it says to partially change the fluid.

Everything that is shown says to change the fluid. Don't see how a partial change can be claimed as proper procedure when it does not say so. So please show me!

I would bet the old school trans service regimen you speak of is outdated these days......The new fluids are light years ahead of old school trans fluids and the transmissions are too smart to hurt themselves like in the old days. Unless there is a catastrophic parts failure of some sort, burnt, smelly fluid full of metal, is a thing of the past.

At least with the 68RFE....it's the same fluid (ATF+4). But the point I was making is that at least for me and likely others, when asked about where a partial fluid change comes from, it comes from the way they always did it in the past.....unless someone shows us otherwise.

It seems that any vehicle I've owned with an auto just had you dump what would come out of the pan, and that was good.

How about you show me where it says to chance running the trans dry pumping fluid out through a removed line. If the factory intended other than just dropping the pan they would have made a provision for draining the cooler and converter.

I'm not disagreeing with you. I don't think anyone on here would disagree that the more fluid that is changed is indeed for the better.

All I'm simply pointing out is the verbiage cited per the manuals above in posts #21 & #22 above do not declare that a "FLUSH" or "EXCHANGE" or "100% fluid swap" must be performed at the time of a drain & fill or drain & fill w/sump filter replacement.

#ad


I have 127,016 miles on my '14. The first drain & fill was at 33,445 miles. My 2nd service drain & fill w/sump filter replacement was at 68,667 (a 35,222 mile interval). My 3rd service was at 102,978....a 34,311 mile interval. I have 82,921 miles of towing with this truck......77,518 logged through the towing trip odometer.

Guess what......the ol' AS69RC shifts better than it did when I drove it off the lot w/11 miles on it. I'm no chemist.....but some how or other, I have a little faith that the service procedure I've followed has not been detrimental to my AS69RC. I'm not like #ad
"I didn't get 100% of the fluid changed all these previous times!!!!!!!!!!!!!!!!!!!!!"

Now someone please SHOW me where it says to perform a "FLUSH" or "EXCHANGE" or "100% fluid swap". :-laf

Hey do what you want I have done this to MANY transmissions without harm. When the fluid starts to sputter it sure is not going to hurt a darn thing. But hey that is MY OPINION and if someone wants to do a full fluid exchange I clearly described a easy to do it.

 

[Cummins12V98]

Still waiting on something in writing showing to ONLY drain the pan. I really don't care but I get jumped all over for saying that "I" will change all the fluid and filter because that's how I want to do it. Then I get only the pan needs to be drained and refilled without anything in writing saying so. Everything says to change the transmission fluid. Or I get the sky is going to fall if you let the fluid sputter when doing an exchange as I have described doing.

You have, on more than one occasion, questioned a few people with "why only change part of the fluid?" and stating that it doesn't make any sense. Well, even though we can't prove (yet anyway) what the current procedure is, the partial has been the procedure for a very, very long time and for most, if not all manufacturers. That's why to many of us, a transmission fluid change involves only draining what comes out with the pan.

I'm not saying it is the correct way for the new transmissions or not, but, it is not as ridiculous as you make it sound because, well, it has (or was) always that way.

Ugh, service manual note for a 2013:

TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:

Remove dipstick and insert clean funnel in transmission fill tube.

Add following initial quantity of Mopar® ASRC ATF to transmission:
If only fluid and filter were changed, add 6.8L (7.2 quarts) of ASRC to transmission.

If transmission was completely overhauled and the torque converter was replaced or drained, add 13L (13.75 quarts) of Mopar® ASRC ATF to transmission.



Check the transmission fluid and adjust as required.




I seem to recall reading this elsewhere before I bought a manual as well.

Finally!
Things have not changed apparently.
