After much waiting here is the DIY flush procedure for the U660E/U760E transmission of the FWD Toyota's without a dipstick. Did this on my brother in law's 2008 Camry with 70K on it. The fluid initially looked good but there was a noticeable difference in look between the old and new fluid.
This procedure applies directly to the 2007-2011 V6 and 2010-2011 I4 Camry with the 6 speed automatic transmission. This transmission calls for WS fluid so you can use ant WS compatible fluids. This procedure will be similar for all 2008+ Avalon, 2007+ ES350, 2011+ Sienna, 2010+ RX350, 2009+ Venza, or any other Toyota with a similar setup.
Note: U660E and U760E use a different cooler hose setup. The difference does not change the DIY in any material way.
Disclaimer: Myself or Toyotanation are not responsible for any damage or injury that may result from use of the DIY. Automotive maintenance and repair should be performed by qualified technicians. This DIY is for informational purposes, use it at your own risk.

Fill plug gasket: 90430-18008 (fits almost every single Toyota transmission all the way back to the 90's). If you need a lot you can buy Dorman 095-149 from Amazon and save money from the dealer price.
Inspection plug gasket: 90430-12008 or 90430-A0002
Note: Having a helper here is highly recommended but not required.
Let's begin!
1. Drive the car around the block one time to warm up the fluid then park the car on a level surface, set the parking brake and place the selector in park. Shut engine off and open the hood.
2. Jack up the car and secure it on jack stands. I like to use the nub located on the front subframe to jack in the front. The nub is located about center of the car. Lower the car onto jack stands on the pinch welds or frame rails.
3. Remove the driver side lower splash shield. Depending on who has worked on your car previously or any kind of curbs you may have hit some of these may be missing. Here is when it would be a good idea to have extra clips handy (I broke 2). Using your flat head screwdriver remove the 3 push clips holding the splash shield by prying out the center section and removing the clip. Remove the 5 10mm screws securing the splash shield and small mud guard piece to the car and remove the splash shield and mud guard.
4. Remove the driver side inner splash shield. Turn the steering wheel all the way to the left. Remove the inner splash shield by removing the 2 10mm bolts using your 10mm socket and ratchet or impact and 1 plastic clip by depressing the center of the clip down until it unlocks and then using your fingers or screwdriver to remove the clip. Remove the inner splash shield from the vehicle.
5. Remove the transmission return hose from the radiator/transmission cooler. Locate the cooler hoses which go from the radiator to transmission (2GRFE V6 with U660E) or transmission cooler to transmission (2ARFE I4 with U760E). On the 2GRFE V6 with U660E the return hose is towards the driver side and the supply hose is towards the passenger side. On the 2ARFE I4 with U760E, the return hose is towards the passenger side and the supply hose is towards the driver side. To verify which outlet is the correct return hose outlet, remove both hoses from the radiator/transmission cooler outlets and set them into a bucket. Briefly start the engine for around 2-3 seconds and observe the hoses. The hose that has fluid pumping out is the supply hose and the hose that does not is the return hose. Then reconnect the supply hose to the cooler supply hose outlet and attach your hose section to the cooler return hose outlet (2ARFE I4 with U760E) or vinyl tubing to the return hose itself (2ARFE I4 with U760E).
To remove the hoses, using your needle nose pliers depress the ears of the hose clamp and slide the clamp down the hose (angled needle nose are priceless here). Using your hose pliers or very small pocket screwdriver break the hose and line seal and slide the hose off of the line.
NOTE: It is a good idea to have your drain pan and container in position here to avoid spilling fluid on the ground.
2GRFE V6 with U660E:
2ARFE I4 with U760E:
6. Pump out one quart of fluid. Attach your section of 3/8" or 7/16" hose to the radiator outlet (2GRFE V6 with U660E) or insert your 5/16" ID by 7/16" OD clear PVC/vinyl tubing into the return hose itself (2ARFE I4 with U760E). After ensuring the hose/tubing is well inside your suitable drain container start the engine and allow the transmission to pump out a bit less than 1 quart of fluid. When it is about there shut off the engine. You will notice that after you shut off the engine, a small amount of fluid will drain out. This is where a helper is valuable.
Note: The transmission pumps fluid at a relatively easy rate. You are not in danger of pumping out all of your fluid unless you are not paying attention.
Warning: Hot transmission fluid can cause burns or injury. Take proper precautions when dealing with hot fluids.2GRFE V6 with U660E:
2ARFE I4 with U760E:
7. Fill the transmission with exactly 1 quart of fluid. Remove the transmission fill plug using your 15/16 inch/24mm socket, ratchet, and extensions. Insert your funnel or pump and add 1 quart of fluid into the transmission. Reinstall the fill plug finger tight only since it will be coming off several more times.
8. Repeat steps 6-7 around 9-10 more times. You will notice by quart 9, the fluid will look brand new. The 11th and 12th quart arr there to top off if you were a little off after the warm up.
9. Reinstall the transmission return hose onto the radiator/transmission. Remove the 3/8" or 7/16" ID hose section from the radiator outlet and slide the return hose onto the radiator outlet (2GRFE V6 with U660E) or remove the 5/16" ID by 7/16" OD PVC/Vinyl tubing from the return hose itself an slide the hose back onto the transmission (2ARFE I4 with U760E). Using your needle nose pliers reinstall the hose clamp in its original position.
10. Check the fluid level. Level the car by jacking up the rear of the vehicle until it's level. Start the car in the air and warm the transmission fluid to the proper temp (104-113 degrees Farenheit/40-45 Degrees Celcius per Toyota). If using a thermometer I like to contact the fluid itself immediately at the overflow point. This way your fluid reading is more accurate to the fluid temp at the sensor. If using a Techstream observe the fluid temp in the data list or place the transmission in inspection mode (I will update this portion of the procedure when I use a Techstream). If using the paperclip, see below.
Note: Some fluid has to come out of the overflow for the thermometer check to work correctly. If no fluid comes out, you will need to add fluid through the fill hole and recheck both flow rate and temperature.
Note: Thanks to forum member Black73 for the following steps.
1. Connect terminals CG (4) and TC (13) of the DLC3 (OBD2 connector under steering column) using a small paper clip or jumper wire to jump PIN 4 and 13 together. Keep note of the orientation of the 16 pin DLC3 connector when jumping the terminals.
2. Move the shift lever back and forth between the NEUTRAL and DRIVE positions at 1.5 seconds interval for 6 seconds.
3. The D shift indicator on the combination meter comes on for 2 seconds when the fluid temperature is within the appropriate temperature range.
4. The D shift indicator will come on again when the fluid temperature reaches 40°C (104°F) and will blink when it exceeds 45°C (113°F).
5. After confirming that the D shift indicator turns off, move the shift lever to the P position and remove the SST from terminals CG and TC.
Cycle the car through the gears with the brake depressed a few times. Using your 6mm allen socket and ratchet remove the inspection plug from the transmission pan. Observe if fluid comes out or not. If no fluid comes out remove the fill plug and add fluid until you get a steady small stream/trickle of fluid draining ( I had to add around another 1/2 quart). Light dripping or heavy flow is a sign of an underfilled or overfilled transmission. When the desired flow rate is reached reinstall the fill and inspection plugs and tighten to 30 lb ft. or snug (tight but not too tight to damage the gasket).
11. Reinstall the driver side inner splash shield. First using your brake parts cleaner liberally spray and clean the transmissino fluid from under the car. Position the splash shield inside the inner fender liner and reinstall the splash shield clip and 2 10mm bolts. To reset the clip you will need to push the center section back out past the flush position using your fingers. Then insert the clip and depress the center until it is flush.
12. Reinstall the driver side lower splash shield. First using your brake parts cleaner liberally spray and clean the transmission fluid from under the car. Set the splash shield into position (remember that at the front of the splash shield/bumper area the splash shield extensions go under the bumper. Install your 3 clips and 5 screws. Be sure the the mud guard piece goes on the outside towards the wheel area. Remove the drain pan from under the car.
13. Lower the vehicle off of jack stands.
14. Go for a good long test drive of at least 15 minutes and try to get the vehicle up at highway speed and verify shift quality.
Admire your work and money you saved!
I did this entire flush for around 80 bucks your cost may be slightly higher depending on fluid cost. The going rate where I live is $189.95 and who knows what fluid is used.
Hope this helps.
