Anyone have specifics on doing a full A/T fluid change? Procedure details and amount of time it took you to do it? Or are you guys just doing the ~3-4 quart pan fluid drain and fill?

I'm at 60k and my mechanic is doing fluid swaps. He's disinclined to disconnect the cooler lines and do a fluid transfusion, in part based on the amount of time he thinks it will take and in part because he says its difficult to properly measure the fluid input and make sure the level is right (he has some concerns about possibly not getting enough fluid into the system and running the TC low, causing damage I think).
 
It might be worthwhile for you to buy a short term subscription to Toyota's online tech service here: https://techinfo.toyota.com/techInf...urce_url=https%3A%2F%2Ftechinfo.toyota.com%2F

I do this occasionally, and did it some time ago when I first bought by 2013 LC. At that time I reviewed the full transmission fluid replacement procedure and, to the best of my recollection, the procedure required both a physical lockout of a part of the transmission fluid stream (placing a pin or similar into an exterior fixture on the transmission) and use of the Techstream computer to lockout or lock open internal fluid valves. At that point, I decided that when the time came, I'd just bring it to the dealer and have them do it right.

Sorry this doesn't completely answer your question, but I would caution that it is doubtful that your local mechanic could do a proper job of it. Of course, I could be all wet and the fluid change in actuality is not as complicated as the Toyota manual makes it seem.

Update: My mechanic called the local Toyota dealer and after he does the other fluids he's going to take it over and let them do the A/T fluid. They evidently have a specialized pump to do the fluid exchange, and they only charge 1 hour of labor. win-win.

Sounds like a good plan ;)
 
Yup, just did an OCD fluid change with 30k miles at a local dealership for $250. Odd that the other dealer in town wanted $500. After consulting the FSM, I came to the previous conclusion of just taking it to the dealer.

Title: AB60F AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION FLUID: ADJUSTMENT; 2013 MY Land Cruiser [01/2012 - ]
ADJUSTMENT
NOTICE:

  • This transmission requires Toyota Genuine ATF WS.
  • After servicing the transmission, you must follow the ATF adjustment procedure.
  • Maintain the vehicle in a horizontal position while adjusting the fluid level.
1. PRELIMINARY PROCEDURES

(a) Using compressed air or equivalent, blow dust off the thermostat cap to clean it.

(b) Using a screwdriver, push in the shaft of the thermostat.

HINT:

  • Pushed amount: 5.5 to 7.0 mm (0.217 to 0.276 in.)
  • Push in the shaft until the screwdriver contacts the step inside the cap.
(c) With the shaft of the thermostat pressed, insert a pin into a hole on the side of the thermostat cap. Insert the pin until it passes through the hole on the other side of the thermostat cap to fix the shaft in place.

HINT:

Pin diameter: 1.0 to 1.8 mm (0.0394 to 0.0709 in.)

2. BEFORE FILLING TRANSMISSION

  • When you have replaced the entire transmission, transmission pan, drain plug, valve body and/or torque converter, proceed to the "TRANSMISSION FILL" procedures.
  • When you have replaced the transmission hose and/or output shaft oil seal, proceed to the "FLUID TEMPERATURE CHECK" procedures.
3. TRANSMISSION FILL

(a) Remove the refill plug and overflow plug.

C161092E02.png

(b) Fill the transmission through the refill hole until fluid begins to trickle out of the overflow tube.

C161094E02.png

(c) Reinstall the overflow plug.

(d) Fill the transmission with the amount of fluid listed in the table below.

Reference Capacity:

Repair

Fill Amount

Transmission pan and drain plug removal

2.1 liters (2.2 US qts, 1.9 Imp. qts)

Transmission valve body removal

4.7 liters (5.0 US qts, 4.1 Imp. qts)

Torque converter removal

6.1 liters (6.4 US qts, 5.4 Imp. qts)

(e) Install the refill plug.

HINT:

If you cannot fill the listed amount of fluid, do the following below:

(1) Start the engine and idle it.

NOTICE:

Check that electrical systems such as the air conditioning system, audio system and lighting system are off.

(2) Move the shift lever through the entire gear range to circulate the fluid.

(3) Wait for 30 seconds with the engine idling.

(4) Stop the engine.

(5) Remove the refill plug.

(6) Fill the transmission with the remaining fluid until the amount in the table has been reached.

(7) Install the refill plug.

4. FLUID TEMPERATURE CHECK

NOTICE:

The ATF temperature can be confirmed by using the Techstream.

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON.

(d) Enter the following menus: Powertrain / Engine and ECT / Data List / A/T Oil Temperature 1.

(e) Check the ATF temperature.

NOTICE:

If the ATF temperature is above 48°C (118°F), turn the ignition switch off and wait until the fluid temperature drops to between 43 and 48°C (109 and 118°F).

5. FLUID LEVEL CHECK

NOTICE:

  • It is necessary to change to temperature detection mode in order to idle the vehicle appropriately.
  • The ATF temperature must be between 43 and 48°C (109 and 118°F) to accurately check the fluid level.
(a) Enter the following menus: Powertrain / Engine and ECT / Active Test / Connect the TC and TE1.

Standard condition:

Indicator lights on the combination meter blink.

HINT:

When not using the Techstream, using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

(b) Start the engine and idle it.

NOTICE:

Check that electrical systems such as the air conditioning system, audio system and lighting system are off.

(c) Slowly move the shift lever from P to S, then change the gear from 1st to 6th. Then return the shift lever to P.

HINT:

Slowly move the shift lever to circulate the fluid through each part of the transmission.

(d) Move the shift lever to D, and quickly move back and forth between N and D (once within 1.5 seconds) for at least 6 seconds. This will activate the fluid temperature detection mode.

Standard condition:

Indicator light [D] remains illuminated for 2 seconds and then turns off.

(e) Move the shift lever to P and terminate the Active Test on the Techstream.

(f) While checking the fluid temperature on the Techstream, allow the engine to idle until the fluid temperature reaches 43 and 48°C (109 and 118°F).

HINT:

The indicator [D] will come on again when the fluid temperature reaches 43°C (109°F) and will blink if it exceeds 48°C (118°F).

Indicator [D] Indication of ATF Temperature
Below 43°C (109°F)

Looks like this is the same process as fluid transfer on the 4Runner and Tacoma. You can use paper clips and dash indicators to tell when you are to the correct operating temperatures. I successfully did this with my old 4Runner a couple years ago. I'd check t4r.org and tacomaworld.com for additional info (assuming both procedures to get into transmission check mode are the same--I'd check that using paper clips before doing anything else on my own).
 
Transmission temperature is critical to get the proper fill. You can use any scan tool that supports trans temp display. We have local quick lube shops that have burned up Toyota Transmissions because they have filled at the wrong temperatures. Mine took a couple hours and lots of patience. Take a muddy glass of water and pour a clean glass of water in it. It takes several clean glasses to have the first one run clear. Same principle but just keep an eye on the temperature.
 
This site follows the incremental version. They have color test after each exchange which is interesting.

In case you didn't find this thread.



Also, found this while i was looking for that.

 
I am curious why multiple drains and fills process is not sufficient to get the old fluid out and new one in. The fluid does rotate through the system it seems. Thoughts?

Simple.
Its not stickler enough for our personalities.

Contamination. You rain the pan and refill it with new fluid, then pump the new fluid into the system to force the old stuff out. However old fluid is flowing back into the pan at the same time. So the multiple drain-and-fill method using the FSM process only replaces maybe 80% of the fluid.

It is sufficient. 1 down and 2 more to go. After that I will start doing a single drain and fill with my fall or spring oil change.
