Not true.
You can do a complete flush 13 quarts or so by disconnecting the outlet transmission hose that is going to the radiator in the front of the car.
I am going to do this method this weekend. Might even drop the pan and clean the metal filter screen. I'm sure there are magnets at the bottom of the pan as well to be cleaned.

Also look at see if there's another plug on the pan. Seems like there was a check plug. Can't remember though, haven't been under mine in a while. Basically when the temp is right the fluid will slowly run out of the check plug, then you put the plug back and add just a tiny amount and it's full. But again you have to have the temp just right to use this method. That's why I said it would just be easier to measure and refill what came out

This is what I would do.
Add 3 quarts or 3.5 quarts. This is what comes out when you drain the pan.
Check the fluid properly by making sure the transmission is in the required temperature. There is a fluid check screw near the drain plug. Any excess fluid will come out of this tube. If nothing comes out you need to add more fluid and start the process all over again.
Here is how to check initialize the transmission fluid temperature check.

Not one on the 05
it has to be a certain volume at a certain temp, the reason they made it sealed in the first place and made it a dealer service item.
This is a 03 V8. It's the red one.
if you have AAA get it towed to the dealer and let them do it. If you know what you are doing.......you can can drain and fill the sealed trannys without a hitch, however it is a particular task and it takes some attention to detail.
Good Luck man

I'm confused... My pics are in the quote but I don't see anything addressed to my pics....?
I should have been more clear... in the pictures it is showing an 03 (like mine) that has a serviceable tranny. the OP has a 05 without these... sorry for not posting that, and thank you for taking the time to take pictures to try to help another member.

:iagree:
By '05, the trans dipstick had gone the way of nickel candy and 8-track tapes. Do a search, there are several write-ups on the rather extensive, and specific proceedure to refill the 'sealed' transmissions.
And, here I thought we had seen the last of this type of fluid change 'oops' some time ago. I remember when there was one of these posts just about every week or so. It has been a while...............

Since this is a a750 you want to overfill it when cold. Then drive around till you are at operating temp, the fluid will expand with the temp increase, park it on a level surface, then drain the excess fluid. The pan has a lip so only the correct amount of fluid will remain. You have two bolts, one is the drain plug and one is the overfill.
FYI the overfill plug uses an allen wrench.

Considering that the check temp is something like 115 degrees, how does that method not let too much fluid out?

Well hopefully they dont romp on it. Just drive it easy, warm it up, and drain the overfill. Simple.

OK, makes sense.
The official method is so ridiculously convoluted I've always suspected there may be some excessive precision built into it.
so.. I was driving it last night, turning on the highway, and the accelerator just revved..
I brushed it off thinking I was just imagining things.. I wasn't.
I went to a dealership to look at cars and my car "chug chugged" (best way to explain it, kind of a jerking motion) and acted like it might die. I put it in park, shut it off, turned it on and headed home. I had to turn around and take it to the Yota dealership.. I barely made it.
The tranny was slipping so bad. It wouldn't engage, jerked, just revved the engine up. OMG. I am dreading this repair bill. It literally makes me sick.

What? Engineers over engineering simple things? NOOOO!!! *Totally not a sarcastic statement
*But yeah, its such a ridiculously complex and unnecessary way of filling the transmission, I doubt that a few ounces of under or over filling are really going to affect the transmission. I know they can be finicky, but I seriously doubt they're THAT picky.
Does anybody know if the process they used for the Tacoma's (in the link above). Will work for our T4R's? Specifically the part about using a wire to jump pins 4 and 13 of the OBD port then shifting the tranny from "N" to "D" 6 times to enter tranny temp check mode???
So again, do WE jump pins 4 and 13 and use the same shift sequence as listed above?
Thanks!
Yep. Same process. Itll take about 15 minutes to get it to temp unless you drive around for a few minutes, then put it in check mode. I upped the temp of mine by putting it in drive or reverse and holding the brakes while giving a tiny amount of gas. It increases the friction in the TC. Probably not the best in the world but I was tired of waiting for the temp to come up. I used a scan gauge to monitor the temps and they were spot on with the a/t oil light. I made a thread about it last week..
