AC60E Transmission, how much fluid drains out?

Hi Everyone,

I have a 2022 SR Taco with the AC60E which if I understand correctly, is a unique version of the 6 speed automatic Toyota transmissions. It has fewer parts, more simple which I love. I plan to get 300,000 miles out of it easily. I do a lot of my own maintenance on vehicles being a public school teacher. I keep my trucks and cars a long time, got 17 years out of my last truck that needed no major repairs.

Anyways, I'm at 17K and plan to do a drain and fill for the transmission by 25K and since I doubt I have access to a bidirectional scan tool, I may have to do a drain and fill where I measure how much comes out.

But I don't trust that because when I first got the truck, I noticed a small leak at the plug and my dealer dropped the pan to do a full inspection, replaced the fluids, and put new seals on and then torqued correctly. (They think the factory undertorqued).

Since i'm not sure if the dealer put in the correct level like the factory would, does anyone know approximately how much fluid will drain out of the AC60E so I can see if I have the right amount to replace when it's time? I of course would expect the dealership did the job instructions from TechStream/toyota directions but I have trust issues.

My undrestanding is the AC60E has fewer internal parts, but does it have the same body size as the others but it still may hold different fluid levels I assume. This transmission is rare I believe, only on 4 cylinder rear wheel drive Toyota trucks which would be some Tacomas in USA?

thanks.

 

I thought all the 3rd gen had same A/Ts, regardless of engine and 4x4 option.

 

search for drain and fill procedure
it's the only way to be sure of the correct amount of fluid is in the transmission

 

Not sure what my trans model # is off hand (‘16 V6 auto 2wd), but typical drain and fill is 3 quarts. That being said… the first time I did it, it took about 4 quarts to fill to get it to the proper level using the level check procedure. You don’t need a scan tool to check the level… there are a few write ups on it with the Toyota procedure.

 

No,

Very few people know about the 4 cylinder Taco that has the old school cast iron 2tr-fe engine. And around 2018 or 2020, the started coming with a really cool simplified 6 speed transmission that has fewer clutch packs than the standard 6 speed. I think it's only found in the Tacoma because it's for rear wheel drive.

I wonder if it has to with when they stopped offering the manual transmission for the 4 cylinders?

But it's cool that have less parts. I think that means it has less chance for failure, hopefully.
Here's the article on it.

Thanks,

So you mean the right way is to do the procedure where you know what operating temperature the transmission is. That means a bidrectional scan tool if you are saying it's the best way.
That's true.

But.......if someone simply published exactly want comes out of a properly filled one and your truck is completely level, measure how much could work.

But I agree that if no one has published how much comes out from a factory filled AC60E....then the only way is for me to do the proper procedure. I agree.

 

You can use built-in temp check mode. On newer models, you need to move the shifter in specific the sequence to put the truck in tranny temp mode without additional steps.

 

Most of us, as you know, have the AC60F transmission. We will be of little help with actual experience.

There is a long thread somewhere on here about the drain (partial) and fill procedure for the AC60F, perhaps you have already found it. My advice is to find it, read through it and understand that there is a lot of discussion of the Toyota factory not properly filling the AC60F transmission, your AC60E may suffer the same. This is contrary to your confidence in the factory.

A dedicated scan unit is not required for the AC60F check level procedure; early units used some pins on the OBD2 connector to put the vehicle into a fluid level check procedure. My 2021 does not have one of those pins installed and instead relies upon a procedure you get into by... well, I forget, but it was all done with buttons and gear shift changes. See if your AC60E can be put into the check ATF level procedure in the same manner, i.e. you very likely do not need any extra tools such as a scan tool or Tech Stream. It will take a bit of reading in that thread to comprehend, but once you do I think you will be on your way. If a similar procedure works on your AC60E then you got it made. I would suggest practicing the procedure once you find it and are confident it is what you wish to use as some find it tedious.

There is also a 11,000+ page Service Manual someone posted for the 2016MY that might have some missing detail.

 

Thanks everyone, this is all very helpful and I'll do my reading. I'm planning ahead so I'll take my time. Thanks
