Transmission fluid capacity

Was thinking about changing my transmission fluid and filter pretty soon. Was just wondering how much fluid the transmission is supposed to hold. It’s the 5 speed auto (Limited).
Do you
have the same problem?

There is a procedure for that transmission that involves more than just draining the fluid and refilling. Fluid used is DIAMOND ATF SP II M or SP III

1. Disconnect the hose shown in the illustration (first image) which connects the transmission and the oil cooler. Place a container under the hose to collect the discharge.
2. Start the engine with the transmission in neutral and let the fluid drain out.

Caution: The engine should be stopped within one minute after it is started. If the fluid has all drained out before then, the engine should be stopped at that point.

3. Remove the drain plug from the bottom of the transmission case to drain the fluid. (Second image)

As you are planning on changing the filter step 4 gets modified a bit, just reinstall the plug so it doesn't leak. You will replace the filter and gasket after you remove the pan after step 6

4. Install the drain plug with a new gasket, and tighten it to the specified torque.
Tightening torque 24 ft-lb
5. Pour new fluid in through the oil filter tube.
Adding approximately 6.3 quarts

Caution: Stop pouring if the full volume of fluid cannot be poured in.

6. Repeat the procedure in Step 2 to pump out the rest of the old contaminated fluid.

Here is where you will drain out the fluid from the pan as in step 3 and then replace the filter. This way gets more of the old fluid out than refilling the transmission and not changing the filter. Also at this point most of the fluid is new so you won't be sending dirty fluid through the new filter. It uses a bit more fluid but gives a better result.

7. Pour more new fluid in through the oil filler tube.
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 1 - 2 minutes.
10. Move the selector lever through all positions, and then move it to the "N" position.
11. Check that the fluid level is at the "cold" mark on the dipstick. If the level is lower than this, pour in more fluid.
12. Drive the vehicle until the fluid temperature rises to normal temperature 158 - 176 F, and then check the fluid level again. The fluid level must be at the "hot" mark.
13. Firmly insert the dipstick into the oil filler tube.
