Well my ES350 is up to 50,000 miles so I decided it is time to flush the trans because I don't ever want to run ATF 100k like the manual says. I did it today successfully via the trans cooler lines and the old fluid was very dark red and stunk quite a bit.
12 quarts WS ATF ( $6.60/qt by the case at a Toyota dealer)
Crush washer gaskets for the drain & fill plugs.
Engine & trans must be completely cold. (best if sat overnight)
The trans fill plug is located by removing a small plastic splash panel in the drivers side wheel well. (15/16) It is stamped WS on the plug. Turn the wheel all the way to the left for easy access.
The drain/dip tube plug is on the bottom of the trans pan (6mm allen)
Remove the wheel well spash piece exposing the fill plug. Break the plug loose.
Remove the driver side plastic under pan exposing the 2 rubber cooler lines on the bottom of the trans.
Remove drain/dip tube plug from trans. About 1 quart of ATF will drain out
Replace drain/dip tube plug in trans pan snug but do not torque
Remove fill plug and insert hose/funnel balance funnel on strut spring in wheel well
Add 1 quart of WS ATF leaving hose in fill hole.
Remove the clamp (slide up hose with pliers) on the cooler line on the drivers side
Slip cooler hose off fitting aim into bucket
Slip clear tubing over cooler fitting aim into bucket
Have helper start car....2 quarts of fluid will pump out. When air pumps out shut off car immmediately.
Add 2 quarts of WS ATF to fill hole with funnel
Repeat pumping out 2 quarts at a time starting car and shutting off quickly until you have pumped 11 quarts through.
You should have 11 quarts out and 11 quarts in( be sure to count them)
By 11 quarts the fluid should be coming out clean.
Reconnect cooler line with factory clamp
Add 1/2 quart WS ATF in fill hole. Install fill plug snug but do not torque yet
Start car and check for leaks.
Cycle trans shift lever through PRNDL 3 times
With car running check trans oil pan with IR thermometer until it reaches 104F
AT 104F remove trans pan drain/dip tube plug and allow fluid to drain until it becomes a trickle. Quickly install plug back in pan. ( about 1/2 quart came out of mine)
Shut off engine.
Torque fill plug to 35 foot lbs
Torque pan drain dip tube plug to 30 foot lbs.
Start car and test drive 5 miles and check for leaks.
Replace plastic underbody and splash panel.
You are done.
Note: the car should be level for the trans oil dip tube measurement so since my ES sits low in the front I used 2 floor jacks to lift the front end about 6" .
Good luck hope this helps.
The TC I found states to add 200ml back in (about 6.7 oz), here is the last page of the Tc:
TRANSAXLE FLUID LEVEL – TC011-07 August 11, 2007
Page 5 of 5
5. Check the ATF fluid level.
NOTE:
The fluid temperature MUST be between 104 and 113°F (40 and 45°C) to accurately
check the fluid level.
A. Remove the overflow plug with
the engine idling (A/C OFF).
HINT:
Removing the overflow plug before
reaching fluid check temperature
makes it easier to confirm when fluid
starts coming out at a steady rate.
B. Check that the fluid comes out of the overflow tube.
If fluid does NOT come out, proceed to step 6, “Refill the transaxle’’.
If fluid comes out, wait until the overflow slows to a trickle and proceed to
step 7, “Complete the transaxle fluid level Inspection Procedure’’.
6. Refill the transaxle.
A. Remove the overflow plug and gasket.
B. Connect the transmission fill system pump and hose to the quick disconnect
adapter already connected to the refill hole.
C. Add ATF into the refill hole until ATF flows from the overflow tube.
D. Wait until the overflow slows to a trickle and proceed to the
“Complete the transaxle fluid level Inspection Procedure’’ procedure in step 7.
7. Complete the transaxle fluid level Inspection Procedure.
A. Install the overflow plug with a NEW gasket.
B. Add an additional 200 ml of ATF WS through the refill hole.
