About this product
Refilling a transmission through a gravity spout is slow, and half the oil usually ends up on the floor. This pneumatic filling tool pressurizes the reservoir with compressed air and pushes oil through a hose directly into the fill port, in whatever orientation the vehicle demands. Suits gearbox oil changes in workshops and for DIY drivetrain service. Before ordering, confirm the following: 1) the included adapters and hose fittings match the fill ports on your vehicles — adapter sets vary between versions; 2) you have a compressed air source and the tool's stated pressure range matches it; 3) the fluid types you work with are within the tool's rated use; 4) the package contents list against what arrives.
