Hand-pressurized 3-liter fill pump with 12 ATF adapters for refilling sealed transmissions that have no dipstick, plus diffs and transfer cases.
Trying to refill a Toyota Tacoma, 4Runner or FJ Cruiser automatic that has no dipstick, only a refill plug and an overflow plug on the case? This 3-liter fill pump is made for that job. It pushes ATF up into the refill hole under steady hand pressure, with a gauge to show tank pressure and a ball valve to stop the flow the moment fluid starts to trickle out of the overflow tube.
The label lists 10 to 30 psi as the working range and 40 psi as the maximum. Low, even pressure is the point: it is enough to move fluid uphill into a side fill port but slow enough that you can stop exactly when the level is right.
Many Aisin-built automatics use an overflow-style level check instead of a dipstick. The Toyota A750F 5-speed in the FJ Cruiser, and its A750E and A750F relatives in the Tacoma and 4Runner, are a good example. The refill plug is on the side of the case and the level is set by an overflow tube inside the pan. You cannot pour into that hole from above, and a squeeze bottle takes forever. A pressurized tank does it cleanly in one pass.
Toyota's repair manual for the A750F lays out the sequence, and it shows why this tool helps:
That 30 mm limit is the reason the kit has both threaded adapters and a short bent tube. Thread an adapter in where it fits, or use the tube just inside the hole. The manual also calls for Toyota Genuine ATF WS, which we stock as Toyota Genuine ATF WS in a 6-quart pack. For more on the Tacoma units and why the fluid spec matters, read our Toyota Camry and Tacoma transmission service guide.
The same tank fills differentials, transfer cases and manual gearboxes through their side fill plugs, and works on other overflow-check units such as the Toyota U660E; see our U660E fluid type and capacity guide. If your fill port does not match one of the 12 adapters, a larger set like the 33-piece sealed transmission adapter kit fills the gaps. You can find more Aisin-built transmission parts in our Aisin collection.

Yes. The A750E and A750F in those trucks use a side refill plug and an overflow tube, and this pump is made for that kind of fill. Use the bent tube or an adapter that keeps the nozzle within 30 mm of the hole opening, as Toyota specifies.
Three liters, a little over three quarts. That covers a typical pan and drain plug service. Toyota lists 1.7 liters for that job on the A750F. Valve body or converter work needs a refill of the tank partway through.
The label gives 10 to 30 psi as the working range and 40 psi as the maximum. Start low and raise it only if the flow is too slow.
Yes. It also handles differentials, transfer cases and manual gearboxes. Clean the tank and hose between fluids so ATF and gear oil never mix.
For an accurate level, yes. Toyota sets the A750F level between 46 and 56 C fluid temperature, read with a scan tool or the A/T oil temperature light method. The pump gets fluid in; the temperature check makes sure the level is right.
