I am preparing to do service on my friends QX4. I do not have a machine that I can use to pressure all the fluid out but I would like to know what other ways I can get all or most of the fluid out of the transmission?

We plan on replacing the transmission filter as well.

Thanks.

Hello and thanks for donating

First, drain the fluid from the pan. Once you've replaced the filter, the pan gasket, and reinstalled the pan, you're ready for the next step.
Fill the transmission to the proper level using the proper type of transmission fluid. Then disconnect the return transmission line (the line in which transmission fluid flows from the transmission cooler back to the transmission), located. Once the line has been disconnected, attach a clear piece of tubing to the transmission cooler, the same diameter as the transmission line, approximately 5-6 feet long, using the transmission line clamp to secure it.
Place the unattached end of the clear tube in a plastic, one gallon milk container and place it where it can be seen ( not under the car).
For the next portion of the procedure, make sure that the parking brake is set prior to continuing. Start the engine. The transmission needs to be put into "Drive" so the torque converter fluid is changed as well. Some transmissions will only circulate fluid through the torque converter only in drive. This especially applies to the electronically controlled transmissions.
After approximately 4 to 5 quarts (obviously, if it's more than 4 quarts, you'll have to turn of the engine, and fetch another milk jug) of fluid have been pumped out, you should notice a change in the color of the fluid. It should go from a brownish red color, to a bright pinkish red color. When this happens, all of the old fluid has been replaced with new fluid.
Be careful not to overfill the tranny during this procedure.
When completed, reconnect the transmission return line to the transmission cooler. Check the fluid level as you normally would, and add fluid as required.
