Why you need it

  • Most automatic transmissions have no dipstick now; fluid goes in through a side fill plug with the car level.
  • Differentials and transfer cases are filled the same way, often with thick 75W-90 that will not gravity-feed.
  • A hand pump screws onto the quart bottle and pushes fluid uphill through a hose.
03

What to look for

  • Thread adapters for the common quart and gallon bottles.
  • Hose long enough to reach from the ground to the fill plug (3 ft or more).
  • For ATF, a dispensing extractor with a measured tank lets you put back exactly what you took out.
