Pressurized 3-liter hand pump that pushes ATF up into hard-to-reach fill ports on ZF 8HP, 6L80E and side-fill transmissions without a mess.
A 3-liter pressurized fill pump built for the job every side-fill transmission makes miserable: getting fresh fluid up and into a fill port you can barely reach with the pan hot. You fill the tank, pump the handle to build a couple psi of pressure, open the valve, and the fluid feeds itself up the hose and into the case while you keep your hands clear of the exhaust. No squeezing a shampoo-bottle pump 200 times, no burned knuckles.
It works well for automatic transmission service on units that fill from the side or bottom - ZF 8HP (8HP45/8HP70), GM 6L80E and 6L90E, and other check-plug fills where you need to add fluid against gravity during the hot-fill leveling step. It also transfers gear oil and heavier 75W-90 manual-transmission fluid, though thicker fluids move slower and are worth pre-warming.
The outlet is a bendable metal gooseneck with a small clip on the end, so you can shape the hose around the exhaust and hang it in the fill hole to run hands-free. Keep the tank pressure low - roughly 2 psi is plenty; this is a fluid transfer tank, not a pressure vessel. The reservoir is graduated so you can track how much you have pushed in.
