Slippery Pete - Fluid Pump for Standard Quart Bottles - 8cc per Pump Stroke and 3rd Hand Adapter, Transfer Gear Oil, Transmission and Differential Fluid (28mm)

This little guy makes changing fluid in a transfer case or differential SOOOO EASY on the refill phase. I was a bit worried about the clip on the fill tube getting stuck inside the holes but went slow and it worked perfect.

This is a handy little product. Especially for filling, transfer cases and transmissions when you have a four-wheel-drive vehicle. It was so simple to use, screw on the cap and start to pump. I would definitely recommend this. I used the 28 mm version for standard oil cans.

Works perfectly, used it to put new gear oil in my front and rear differential. It did not leak and the plastic piece held the tube in place perfectly with no leaks.

Pump works as described. Made the job much easier.

Used it for both ATF and relatively thick transfer gear oil. Works like a charm. The transmission fluid was upright the whole time, so I don’t know if it would leak out the top, but the gear oil didn’t leak when pumped sideways under the car.

This product worked great, the only thing I would have to say that wasn’t perfect is the threads are for the older more narrow oil bottles, what I needed it for was the wider mouth, but the product still worked great!

Since I do my own fluid changes for the transfer case and differential, these pumps came in handy. It takes a few pumps but it gets the job done and keeps it clean. I prefer these over the compressed air tank where you put the fluid in to transfer. Even though I needed the two sizes to fit on the different jugs, it was still worth it because I didn't make a mess.

You get a good pump for a good price. It is easy to use and easy to clean.
