JoyFans 10L Pneumatic Automatic Transmission Fluid Extractor and Dispenser

Work incredibly well. Serviced my Mercedes trans and bleed brakes with it too.

I’ve never had a uses for this type of system until I picked this boat that has only one way to get the oil out of the engine. So I order this not really knowing much about how it all works. I am pleased to say that it worked great. No mess and no headache from uses it. Very easy to operate and very clean. Thanks

So it did the job. Seems to be built well. Only complaint is that it should come with a regulator so that it isn’t always blowing the safety check valve open to relieve pressure. It’s kinda annoying!!

Used to replace transmission fluid on Touareg; made the job a jiffy. The right tool to handle heavy fluids.

It takes forever to extract all the oil out of the engine. Its probably faster to get on the floor and removing all the plastic paneling from underneath it and drain the oil that way.

This works very well for adding small amounts of specific fluids. We use it in our professional shop when we need to add 1-5 ltrs of transmission fluid, transfer case fluid, or something else where we only need to add a small amount. It works well except the controls on it that direct you to twist the knob and the lever to switch between extraction and filling are backward. When you put it on extract, it tries to push fluid out, and vice versa. It's not a big deal, just kinda annoying. But, it does work well. It has sturdy construction and is big enough to fill a transmission without having to add more fluid to the dispenser.

Working with no issues so far so good

I started to use it today very quick and easy to use. Before I used manual hand pump when I saw this decided to get one.
