Introduction: Vacuum Extraction of Transmission Oil! - Hyundai Trajet 2000.

About: Update 12 September 2017: A very special thanks to Sam Elder, a manager here at Instructables, who tracked down the cause of my lost publications and fixed the issue. Take a bow Sam!

OK it's time for my wife's car to have the transmission oil and filter replaced. My diy vacuum extractor, 4 quarts of atf oil and the filter are needed to do this job.
Read on for how I did this in less than half hour!

Step 1: Preparing for Extraction.

With my diy extractor in place, I removed the dipstick and inserted the tubing. Mind you the tubing shots go about 2 inches deeper than the dipstick. Any lower and no oil may be extracted. It's a tricky arrangement sometimes with oil extraction via the dipstick tube.

See one of my doggies just breezing behind the car? She doesn't care about car maintenance. The same can be said of my wife.

Step 2: Extraction!

The vacuum extractor quickly removed 4 quarts from the transmission sump. I emptied the oil into a gallon container and disposed of it properly.

Step 3: New Oil and Filter!

Using only my hand I removed the old filter. I put some fresh oil onto the rubber seal of the new filter and screwed it on. Yes people, there actually are transmissions with user replaceable filters!

Using a long neck funnel I added 4 quarts of synthetic atf oil.

Now the vehicle is ready for the road!

    YES, MANY MODERN CARS THAT HAVE AUTOMATIC TRANSMISSIONS NOW USE EXTERNAL FILTERS THAT LOOK LIKE ENGINE OIL FILTERS. BRILLIANT IF YOU ASK ME!

    I believe you removed transmission fluid but you replaced an engine oil filter. Is your car set up with an aftermarket transmission filter that uses oil filters?

    Did you replace the transmission filter? All I see in your pictures is an oil filter.
