How do I fill this unit without a dip stick? (How much fluid does it take?)

The exact procedure to fill and check transmission fluid levels are different and vary widely depending on the transmission type. If the tech is unsure, consult our tech department by calling 1-855-GPS-TRAN toll free.
NOTE: Most Hondas require the engine off for a transmission level check.
Some units are filled through the pan with a pump. Others are filled through access holes. Some techs will fill through a speed sensor hole as opposed to the “pump through the pan” method.
The most important step is to start with five or six quarts before you start the engine, keep at idle, and quickly get the remaining transmission fluid in the system. Remember, most remanufactured units already have a couple of quarts remaining from the dyno testing at the factory.
