What transmission Fluid is approved or safe for an Aisin

[brillmtb]

So I have run amsoil in my 5.9 without any issues. I have seen some put Mobil 3309 in their Aisin then there is the OEM oil. Are any of these OK. I am about to do my oil change and filter and I am at 50K, little early but to me oil is cheap since I am doing the labor. Dealer wanted 600.00 for the transmission fluid and filter change

Thanks

I will be using Amsoil ATF in my Aisin.

I called and talked to Amsoil tech's and asked why the factory has 2 fluids (68RFE vs AISIN) and why Amsoil specs the same. They said that in their testing of the OEM fluids there wasn't any appreciable difference, and that the Amsoil ATF meets/exceeds the requirements of both fluid specs.

Signature Series AMZ/OIL ATF.

Just need to figure out how to bi pass the valve on the side of the trans to do a fluid exchange.

I use Mobil 3309 in mine, sticker on the side of the Aisin says it's OK to use. No issues.

So I wonder if the 3309 and the deal labled Aisin fluid are one and the same?

Let’s use our powers of deduction. FCA doesn’t make fluids. They buy them. The only other fluid thats recommended is 3309. The 3309 is in parentheses. What do you suppose?

AMZ/OIL ATF is listed Mopar ASRC on their cut sheet.

They also say it’s the same as ATF+4. Will they warranty the trans if FCA says “ show me your maintenance records” if there’s a problem?
Don’t bother, we all know the answer.

Why would FCA care? Why would you be afraid to show them your maintenance records?

From the owners manual. "Only use Mopar ASRC Automatic Transmission Fluid or equivalent. Failure to use the proper fluid may affect the function or performance of your transmission."

Amsoil ATF meets that statement, no different than Mobil 3309.

j, I suspect they play both sides. They are using the others oil but want you to pay for a transmission if you use anything but what they sell over their counter at a higher price I think I might go for amsoil this time. Heck, with having to change fluid every 30K I think I could put anything in there,.....not really....but you get my point. Its like putting full synthetic in the engine and changing every 5K, overkill but fluid is relatively cheap. Doubt it broke down, contaminants might be there where extra oil filter capacity might hep. And why I am thinking about it....who was the idiot that put my filter in that ridiculous position.

“ show me your maintenance records”

I will try to request the technical backup from AMZ/OIL, as I have no skin in the game here will be interesting to see what they send back if anything, or is it just a marketing ploy, smoke and mirrors.

Why not show them your records. It's no big deal to take a pic of your stuff anymore and save it on your phone. If you buy on line you most likely have the email, if you dump your waste our place needs an appt I have slips for that. I do OA on my stuff have the slips for that. None of this for me is in a nice binder but some basic digging I can assemble it in a day or so.

Carfax wise you can for sometime enter your own records and upload supporting documents on the "mymaintenance" area. Name could have changed.

I have a "dealer approved" place for oil changes, whatever that marketing term means, they are all ASE certified in something there. They have have that paperwork as well and I will ask if they save their records next time I'm in.

Agree the dealer network is thin on good help and a big issue for me, I have a FCA dealer .1 miles from my shop, have a Chevy dealer .2 miles from my shop, I travel 30 miles to my FCA and 35 miles to my Chevy dealer, because of service and sales issues at my local places, find a different dealer who will try to support you. When they turn over plan on moving it's a hassle, I really don't want to use a warranty ever, rather not have issues at all.

Was pretty easy format.

The thing that bothers me about boutique oils is they tend to shy away from obtaining certs like the one in question. You are essentially taking their word it is adequate. Costs are always cited as the reason but they have no problem pumping up the marketing hype about superiority. Results used to matter more than claims.

They would care because amsoil has no documentation to prove their fluid meets specs. Because I say so may work with your children but it won’t with warranty. Claiming their fluid meets both ATF+4 and Aisin specs is more than a little suspect.

Thought I would throw in on this... the dealer filled the Aisin on my 09 4500 with ATF4 when they serviced it. I always read service tickets and when i found they used ATF4 on it, I challenged them about it. They told me it works fine, and apparently, were right. that was back in 2015 and 20K miles when I traded the 09 4500 in 2018.

Cheers, Ron

Guys who pull heavy commercially are getting hundreds of thousands of miles running Mobil 3309, which is reasonably priced, not to mention called out on the decal above. What's to gain when there are no fluid related issues? Especially with 30K service intervals.

What else am I to do at that hour of the AM.... my daughter is getting used to a real bed so she is up at odd hours till she figures out she can actually stay in her bed. Might as well submit technical requests, it was that or figure out to ditch the 6.4 with 4.10s, compared to a '18 6.7 with 3.42 AISIN or 68RFE, dealer is sitting on a few left from when I got my '18, I cant make sense of these 20page reply posts and cant dare start a new one. Was doing some ratio checks on the AISIN. Might as see what type of fluid it could possibly use.

I'm interested in the possible reply and any follow up info or lack there of, they list a ton of oils on that spec by name, so just more curious then anything else. It is smoke and mirrors?

Skip the warrany build stuff that is reasonable to maintain if you choose too do so, I have no room for down time so I'm one to pick OEM anyway...

Driving down the NJ TPK today it's pretty amazing the ratio of Hotshot heavy Rams to others, they are logging some serious miles and weights with these rigs for sure.

Back to the drive...

I've never seen a dealership ask for more than what's on the bottle, but hey it could happen I suppose. Not something I'm overly worried about, considering that ASRC isn't anywhere on the Mobil 3309 spec sheet Kinda funny actually.

3309 and ATF+4 really aren't that different, 3309 is just friction modified to reduce torque converter shutter and harsh shifting due to converter/clutch design. Additionally ATF+4 is synthetic where 3309 isn't, which might have something to do with the shorter drain intervals.. don't know, even if/when I switch to Amsoil I'll stick with OEM drain intervals.

After looking into the fluid spec differences a little more it's understandable why one fluid can meet both specs, which isn't limited to just amsoil.

My biggest desire to change is that I prefer synthetic fluids for there extreme temp operation... even thou I don't spend a lot of time in extremes. Folks who have switched to synthetic fluids in their transmissions that spec JWS 3309/T-IV have noted improved cold weather operation.

I was surprised how long the trans took to heat up the other day while towing on a 41° morning. Granted I got into TC lockup quickly and stayed there, but it took over 25 miles for the trans to get to 163°, which included a 6% grade at 70 mph.
