Drain and refill of pan should take 4 to 5 quarts.
Might want to get 6 quarts if you drain the differential also....
The ATF type you need will be printed on the transmission dip stick.
My 2003 Sienna, with the 1MZFE motor calls for Dexron III rated fluid.
I just changed mine yesterday.......used Redline D4 ATF.
The drain plug on the transmission requires a 10mm hex....might require some convincing to move it.
You might also have a drain plug in the differential.....also takes a 10mm hex.
The differential on my sienna is filled when you fill the transmission through the dipstick tube.
I verified this by putting the pan back on......and filling......until I saw fresh fluid coming out the differential drain......then I stopped and put the differential drain plug back in.
Here is a picture that shows both the differential drain plug and the tranny drain plug......the differential drain plug faces the rear of the vehicle........arrows point to the 2 drain plugs.
I bought the Beck/Arnley transmission filter kit through Rockauto......the filter "media" is just a nylon screen.....the kit came with a rubber gasket....vs the OEM cork gasket.
The transmission pan is held on by 17 x 10mm bolts.
When you put the pan back on, the torque specification is 69 in-lb NOTE INCH pounds......not ft-pounds.
Drain plug torque specification is 36 ft-lb
There are 3 x 10mm bolts that hold the filter in place.
There was a wire that I had to slide out of a clip on the top of the OEM filter.....it will be obvious.
The replacement filter did not have a clip at that location.....not important.
The torque specification on the 3 bolts that hold the filter to the valve body is 8 ft-lb
This is the new filter installed with arrows that point to the 3 bolts that hold it in place.
You can see the nylon screen filter media through the window in the filter case......OEM filter was the same.
Bottom of picture is toward the front of car.
Inside of pan as it came off of vehicle.....note fuzzy magnets in pan.
Pan wiped down, new gasket laid on....ready to install
New Redline D4 fluid next to the old fluid (I think it was Valvoline)....which has just over 30K miles on it.......needed changed.
Some have used Amsoil ATF, others have used Mobil 1 ATF.
Double check what is called for in your vehicle.....it is mostl likely Dexron III specification....but they changed at some point over to Toyota T-IV.....not sure what year they made the change for the Camry.
Read the transmission fluid bottle and verify that it meets the specification that is called for in your owner's manual or on the dipstick, if you don't have the owner's manual available.
I went by feel for tightening all the bolts...but listed the torque specifications in case you want to use a torque wrench.
I also installed a auxillary transmission fluid cooler and a magnefine filter in the fluid cooler line.
The magnefine filter provides 30 micron filtration, has a bypass in case the filter media becomes clogged, and also has a magnet.
