NB: The mileage shown in the video is from my corolla, but I changed the oil on my daughters corolla with ~110,000 miles (175,000 Km).
My process
1. Get 5 qts of AISIN ATF TFE oil from Rock Auto. Filter, O-ring 90301-22014 & Gasket 35168-12091 elsewhere. It’s an Aisin K313 transmission, so a google search for the filter should work.
2. Jack up left front wheel, remove wheel & plastic panel behind it so you can see the fill bolt marked with “FE”. Loosen bolt. Put wheel back on.
3. Drive car up on ramps for 4 wheel lift to keep car level – within ±1° so for wheelbase of 106”, wheel height must be within 106*tan1° = 1.85 inches from level. Handbrake on.
4. Remove tranny drain bolt (6mm allen hex) & drain fluid into container, not drain pan, so quantity can be measured.
5. Remove in order, sump “straw” (6mm allen), sump (10mm hex), filter (10mm hex) and continue draining fluid into container.
6. Clean out bottom of drain pan and magnets & note any debris. Replace magnets in sump pan, replace straw in sump pan, replace drain bolt finger tight.
7. Install new filter with oiled O-ring. (low torque)
8. Install sump pan with new gasket. (low torque)
9. Measure amount of oil drained. I got 4qts + 20 ozs (4.625 qts)
10. Remove fill bolt and use funnel and tube assy to put the same amount of oil back in plus a little bit. Check for leaks.
11. Put OBD connector into temperature sensing mode – see video. I used paper clip
12. Start engine and move the gearshifter thru R, N and D for 3 seconds each. Now shift quickly (1 second each change) from D-N-D-N-D-N etc until the display shows D even when the shifter is at N. Then shift to park.
13. If the D disappears, the oil is cold, remove drain plug. If no extra oil comes out add till it does, ELSE wait for D to show up, when it does, put the drain plug back in, then shut the engine off. If D is flashing, the oil is too hot. shut off the engine and wait for it to cool down
14. Torque the drain plug to 30 ft lbs. 30 seemed OK
15. Replace the fill bolt torque to 36 ft lbs – 36 seems too high, 30 seems right. With plastic panel out the way, torqueing from under the car is easy.
16. Replace plastic panel and wheel 76 ft lbs.
