Tired of making a mess when you try to fill your transmission or differential? Just pour your new fluid into the 1 gallon FTP tank, insert the hook into the transmission or differential fill hole and pump the tank. The PRO version comes with a US made valve to control fluid flow. It also has a shraeder valve if you wish to pressurize the unit using shop air.
Also compatible with specialty transmission fittings. Simple, clean, and easy.
