Introduction: Vacuum Extraction of Transmission Oil.

About: As of April 2017 I have decided to no longer post on instructables. The fact that several of my published works have been removed without my consent is inexcusable. Also the insult of an author having no co...

Every year I replace the transmission oil in all our vehicles. It typically requires removing the drain plug and catching the old oil. This time however I am using my DIY vacuum powered liquid extractor.

Enough of going down low to perform this job! Arghh!

Step 1: The Vacuum Extractor.

My latest tool for car maintenance! I made it from a water pump filter and an hvac vacuum pump.

Step 2: Preparing for Suction!

I removed the dipstick and inserted the vinyl tubing as far down as I could.

Step 3: Extraction!

I was truly impressed with my homemade extractor! In less than 15 seconds the jar filled! In all it took 2 emptying of the jar to complete the job. The valve on top the catch bottle I used to throttle how fast I was pulling the oil.

From the exhaust of the vacuum pump water vapor is seen misting out.

Step 4: Disposal!

Pulling out the suction vinyl tube allows for easy pouring of the collected oil. I used an empty container to collect the oil. Now the job is done and I refilled the transmission with 2.5 quarts of oil!
