Worked great to fill my transmission fluid. Didn't take long at all to fill 4 quarts into my transmission. The black hose adapter held in the transmission so.i had 2 free hands to pump. Very happy with this product, i would by it again if the one I have ever breaks. Only thing I took a star off for was the bottle was to big and I couldn't screw the lid on so there was some oil mess but it was manageable

So much more convenient then angling and squeezing a bottle for filling up a rear differential. Just screw on to the gear oil bottle and pump away. My only complaint is that the hose is rather short, would be nice if it could reach a little farther. When I'm working under my F150. Another handy use for this is for changing my power steering fluid, I just put it in the reservoir, pump out the old stuff before topping off with the new fluid.

this Fluid Pump for Standard Quart Bottles， 8cc Per Pump Stroke, Transmission Fluid Pump is well made and working efficiently.

pumped 5 quarts of transmission oil with no problem, great design , durable

I used this for changing out the differential fluid in my Toyota 4 runner. Pump fits on a standard quart container and pumps/transfers thicker gear oil with no issues. Has two different container straw draw lengths. I just wish the hose were a little longer but for the price I can’t complain.

Works great

Need a way to get transmission fluid into the filler tube that is near the top of the motorhome engine cover and 12 inches away from engine access, this filled the bill without making a big mess. It doesn't fit the large neck bottles so had to improvise, small quantity pump so it takes time to empty a quart bottle but was worth the reduced cleanup.
