OK guys, I am finally doing the write up for my 2001 Corolla 4speed auto transmission drain/filter/refill.
3 hours for your first time, around 1.5 for your second
14 Millimeter socket
12 Millimeter socket
10 Millimeter socket
A big plastic sheet
3.3 quarts of DEX III auto tranny fluid (i used castrol)
White lithium grease
Make sure the engine, tranny, and fluids are warm. You will drain more this way.
Put the car on ramps., and locate the transmission drain plug.
Use the 14 MM socket to take out the drain plug and empty out the fluid.
When the fluid slows the draining, Gently, and CAREFULLY push the front suspension up and down, moving the fluid left in the pan. (make sure the e-brake is on).
Put the drain plug back on, and using the 12 MM socket, start to take out the bolts holding on the pan. Make sure you keep them in order, as you are supposed to put them back in the same spot. Make sure the big plastic sheet is underneath your car because you will get old transmission fluid on the pavement underneath if you don't have it.
the pan will come off, and fluid will get everywhere underneath. Wear eye protection.
Clean out the pan, and make sure you get the old gasket off as well. you can use simple green to get extra clean, but I just used some lint free paper towels.
When you have the pan down and clean, make sure you clean the magnets very well. There are alot of metal shaving on them, but it feels like a grey cream more than metal.
Use the 10 MM socket to get the old filter off. The side that has one bolt is a long bolt. The other two are shorter.
Put the new filter back on. I took some new fluid on the cork gasket. Make sure you use the correct bolts.
Now, with the new filter back on, you need to get the gasket on the pan.
Use the white lithium grease to hold the gasket to the pan.
Clean the bottom of your opened transmission with a lint free cloth to get out any fluid from where the gasket meets the transmission.
This is were two people are needed. One person needs to hold the pan on it, wile the other puts the bolts on the corners on the pan, holding it on while you can get the other bolts on. The bolts should be tightened to 48 inch pounds. Don't guess, use a torque wrench.
Take out the transmission dipstick, and put in 3.3 quarts of transmission fluid via the dipstick. Pour it in slowly, because it has a tendency to come back up and spill out the dipstick.
Roll the car down(with out starting the engine), and wait a couple mins to let all the fluid go down the dipstick. If you don't you will not get an accurate reading. Once you get an accurate reading, add more if needed.
When you do start the car, take a look underneath and make sure nothing is leaking and that the gasket is hold up with no problem. If there is any leak, you might have to redo the gasket by dropping the pan again.
I did this yesterday, and my shifting is much better. I can barely feel the car shift. If you have any problem, feel free to contact me.
This is my first write up for anything. If you have any comments, feel free to tell me.
