Auto Trans Service
Looking to service my transmission soon. Can anyone recommend a really good ATF to fill it with?
Also what about the transmission filter, how do you change that? I've never serviced an auto tranny before.

Whatever fluid you end up filling it with, you'll need about 12 quarts to properly flush/fill the tranny.
Here is where you would normally drop the oil pan and change the filter. However, a bit of research has shown me that although you can buy a filter and pan gasket kit for about $15, the service manual shows the transmission being removed and partially disassembled to change the filter. If the $15 is worth it to you, go pick up one of those kits and see if the instructions come with it. I'd be interested to know if it can be done without pulling the whole tranny apart. If it can't, you can probably return the unused kit.
Carry on.
TRANSMISSION FLUID CHANGE
If you do not have an transmission fluid changer, replace the transmission fluid by the following procedure.
1.Disconnect the longer of the two hoses which connect the transaxle and the oil cooler (inside the radiator). Place a container under the hose to collect the discharge.
The engine should be stopped within one minute after it is started. If all the transmission fluid has drained out before then, the engine should be stopped at that point.
2.Start the engine and let the transmission fluid drain out.
(Running conditions: "N" range with engine idling)
Approximately 3.5 dm3 (3.7 quarts) of transmission fluid should be removed.
3.Remove the drain plug from the bottom of the transaxle case to drain the transmission fluid.
Approximately 2.0 dm3 (2.1 quarts) of transmission fluid should be removed.
4.Install the drain plug with a new gasket, and tighten it to the specified torque.
Tightening torque: 32 ± 2 N·m (24 ± 1 ft-lb)

Carry on.
Stop pouring if the full volume of transmission fluid can not be added.
5.Add new transmission fluid (DIAMOND ATF SP III) through the oil filter tube.
Approximately 5.5 dm3 (5.8 quarts) of transmission fluid should be added.
6.Repeat the procedure in Step 2. (to pump out the rest of the contaminated transmission fluid)
7.Add new transmission fluid (DIAMOND ATF SP III) through the oil filter tube.
Approximately 3.5 dm3 (3.7 quarts) of transmission fluid should be added.
NOTE: Check for contamination or a burnt odor. If the transmission fluid is still contaminated or burnt, repeat Steps 6 and 7 before proceeding to Step 8.
8.Reconnect the hose which was disconnected in step 1 above, and firmly replace the dipstick.
9.Start the engine and run it at idle for one to two minutes.
10.Move the selector lever through all positions, and then move it to the "N" position.
11.Check that the transmission fluid level is at the "COLD" mark on the dipstick. If the level is less than this, add transmission fluid.
12.Drive the vehicle until the transmission fluid temperature rises to the normal operating temperature [70 - 80°C (158 - 176°F)], and then check the transmission fluid level again. The transmission fluid level must be at the "HOT" mark.
NOTE: The "COLD" level is for reference only; the "HOT" level should be regarded as the standard level.
13.When the transmission fluid is less than the specified level, add transmission fluid.
When the transmission fluid is greater than the specified level, drain the excess fluid through the drain plug to adjust the transmission fluid to the specified level.
14.Firmly insert the dipstick into the oil filler tube.
