I love this fluid exchanger. I've changed engin oil , trans fluid, , rear end , transfer case , ps fluid and brake fluid from resevoirs. It works well because i you can suck fluid then pump it out into used container. I have filled it with gear oil and pumped it in . It is also great for boats

 

They are even better when you attach them to shop air...

I have never seen a shop air one that dispenses fluid. I have another metal tank extractor one at that uses shop air at work, but it can only extract fluid. I like my new pump one because it is transparent to see the fluid level. I can extract say rear end or trans fluid mark the level on the exrtractor then pump it out to a waste container. Then fill extractor to marked level and pump it in. I have used it on rear ends, transmission, and transfer case, landscaping equipment. It is slower than air powered extractor but it only requires 5 or six pumps . It is nice tool for garage mechanic not a shop

 

I got one of these at my shop. They are very portable and can be used anywhere.
