I did a flush at 90,000 miles with my major service. Seems a lot of people don't recommend it, but the local Toyota Service recommended it. I just don't think that fluid with that kind of miles would do every thing we ask tranny fluid to do. It's been about 6weeks and 4,000 miles and no troubles so far. I know after the major service the truck runs better, and my shifts are smoother--even increased my gas mileage by 1mpg. Just my .02

My understanding it that if you are at that high of mileage you might as well not touch the fluid. This was just a casual conversation with a friend who is a Cert. Tech. that works at Toyota. I asked the same thing and that was his response at that mileage. Hope this helps.

Hey marcus, what was included in that major service you mentioned?

This should be a sticky as I the same question pop up every week or so.
I did a full flush on mine by removing the transmission return line to the radiator, started the engine for 10 seconds or so that 3 quarts of WS fluid came out. Turned off the car, added 3 quarts of new WS fluid, repeat, repeat, repeat until you see cherry red fluid coming out of the return line (around 13 quarts). Then I properly checked the level by jumping the OBD pins as indicated by the Toyota manual to set the transmission in temperature check mode.
I would personally do a full flush. I do now have the time to do a serial dilution and change the transmission fluid 5-6 times to flush it. This means that you have to check the fluid 5-6 times properly not just add the same amount back in. I rather just do it once and be done with it for 60k miles or so.
Do a search on here and you can see the procedure to do it.
It is extremely easy. The only problem I had was getting the transmission to get into temperature check mode. Had to try 4-5 times.
All I can say is that I am glad I changed my transmission fluid (13 quarts) at 58k miles. The fluid was noticeably dark brown and not cherry red like the new fluid.
Also I would not go to the Toyota dealer to do this. They will charge you $150-200 just to change 3.5 quarts of oil (basically just a fill and drain of the oil pan). Which you can do easily yourself for $40 bucks.
Good luck.

Here is the receipt for the work--its what they recommend, and goes along with what I have read here and what the owners manual says.

hey I really appreciate you posting that, thank you.
Greatly appreciate it too! I'm about to reach the 100,000 mile mark sometime this fall and will need to have a few things serviced.
I just bought an '03 limited with 166000km roughly 100000 miles and did a trans flush by;
1. draining the pan oil.
2. adding 5 liters to trans.
3. disconection trans line at external cooler and droping line into 5 liter jug.
4. Putting vehicle in neutral
5. starting vehicle and filling container with approx 4 liters of old oil at a time until I begin to see clean oil coming out of line.
I ended up going through 15 liters of Toyota oil for a total cost of about $150.00 which is less than 1/2 price for a complete flush if I was to have Toyota do it for me.
:wave:
4runner shifts much better now, much smoother etc.

Not as long as you're happy doing the work. I may try the exchange using the engine pump in the future (long way off) but the drain and fill has gotten so easy for me and it's so safe I'm reluctant to change.
The only risk I can think to mention is tightening the drain bolt. Go easy on it.
