Aisin transmission fluid

[smittyd174]

Everything I change fluid on gets drained at operating temp overnight. In the 70s I didnt really change oil, just added it when the red light came on.

All:
I know the threads on oil, transmission fluid, differentials, powersteering, and maybe brake fluid has different opinions on how to do em. what to use and when, but for my part, getting as much of the old out and the new in is good, however you want to do it. FSM or whatever procedure you use is good.

My final comment on flushing my transmission when filter change required likely puts me in the smallest percentage on the forum and in the universe (statistics term) and it don't bother me at all. And I don't criticize anyone for the way they do it. Its all good, but I won't mention it again.

Cheers, Ron

No worries Ron its your truck and in noway was I making a judgement on you . I agree that it would be nice to do a complete flush but unless you can do it yourself the dealers won't do it. A 7 liter change is about half the fluid so maybe its not so much of issue of dirty fluid but maybe insuring that the additives in the fluid are kept up. Who knows ? Have a Merry Christmas and hopefully the New Year will be a little more normal. Take care , stay safe and drive it like you stole it.

Smitty/All,

I checked with the dealer when my 2017 Ram 5500 was due 30K mile fluid change and was shocked it was going to cost $400 for just a drain and fill; same delaer I got flush and filter on my 09 4500 for $300 in 2015ish. I bought two cases of 3309 and did it for $70. With the drain plug on the pan, I may very well join the DIY gang when the filter change comes up in 20K miles if cost gets rediculous.

EDIT: BTW, what a novel idea for a transmission manufacturer to install an aluminum pan WITH a drain plug.

BTW, my wife had training in Niagra Falls Canada in 2011... made a three week RV trip a week getting there, a week there, and a week back. Great fun... Best Italian food I ever had... Played fetch with my Lab Shepard on Lake Onterio beach, I beleive.

All is good in Pleasantville!

Christmas Cheers, Ron

The fluid capacities should also state all that is needed to be known.

Overhaul: 13.7 quarts
Service Fill: 7.2 quarts

Changing 52% of the fluid is built into the service interval.

I like to do the same, but there is still a large amount of oil left in the engine. Axles drain a little more completely, as do manual transmissions.

Yep!

Greg,
You have the highest mileage, towing wieghts, and duty cycle of anyone I know... do you see any significant difference in color or wear particles when you change your Aisin fluid? I thought you posted once the before and after on a paper towel. I saw some tow numbers comparable to yours when hauling generators and a few things for sure: I'm glad it was with a Ram, a Cummins, and an Aisin. I beleive we all share those bragg'n rights!

Finally, as with all the oil, transmission, and axle fluid threads, it's expected to be lively, but in the end, it's still interesting to see all the positions represented.

Christmas Cheers, Ron

I’ve never witnessed any wear particles except for the first drain and fill and *maybe* the first sump filter changes on either my 2014 3500 (traded at 362k miles with services as @AH64ID referenced) or my current 2018 4500 that happpppppily turned over 280,643 miles as I pulled into my driveway this evening.

The fluid still looks pretty good when I service it. Not long ago.....my cumulative 60,000 mile service was exceed by about 13,000 miles or so (missed the drain and fill by about 6,000 miles +/- and I missed the sump filter change by about 6,000 miles +/-.) The ol’ AS69RC keeps chugging right on along....

Still trying to dissect why ol’ @Cummins12V98 feels the need to berate some on here though....

[Cummins12V98]

I wonder if everyone worried about changing every bit of fluid out realizes how much engine oil is still left in the engine after a 10 min drain......

I let mine drain overnight.

 

[AH64ID]

I let mine drain overnight.

There is still about a quart that stays in the motor, most of it on the head.

There is enough oil in the block that on the trucks with really black oil, mainly 04.5-07 5.9's, the new oil is jet black within seconds of operation.

so if doing ALL the fluid s person could reasonably go longer. Of course after warranty is gone.

You can do anything you want with your own rig... but to get ALL of the fluid changed you will have to remove and overhaul the transmission, clean the cooler, and then put it back together. It's the only way to get ALL the fluid, even your method on the 68RFE didn't get ALL of the fluid and neither will any flush machine.

Now you are picking fly Chitz out of the pepper bowl.

I'm not the one capitalizing ALL.

Either you want to change all, or ALL, of the fluid or you don't. Even a 99% flush is a partial fluid change.

OK

Asian transmission fluid.... I'm sure it's abundant in Thailand.

I just still find it strange that our recent purchase of a Mini Countryman has a transmission fluid change interval of 100k (Aisin 3309 fluid) while my Ram requires it at 30k! It also has no dipstick or fill port. Both drain and fill plugs are on the transmission.

 

[JR]

Intended duty cycles are certainly different between those two.
One reason for manufacturers eliminating dipsticks was to aid in the increased service intervals. The dipstick is a possible source of contamination including moisture/condensation, which will break the fluid down quicker over time.

Just like my 4Runner which has no scheduled change. Different duty cycles, thou I think my Ram is easier on the trans fluid than my 4Runner.

The Mini never gets the chance to pull the 17,000# 5r

Make it happen cap'n!
