Have a transmission fluid leak in a no dip stick sealed transmission? Don't want to crawl under the car and pump ATF into a fill port you can't find? This video will show you how I added ATF (or do a ATF change) working from above the engine! Very simple and straight forward.
I had a customer with leaking ATF fluid coming out of his radiator. I figured his ATF was low since his transmission was shifting erratically and the check engine / MIL lamp was blinking. After I changed the radiator, the next step was to figure out how much fluid leaked out. I disconnected the ATF transmission supply line between the trans and radiator and pressure injected in a quart of ATF via the line connected to the radiator. I took the car out for a test drive and guess what - the transmission starting shifting better. I knew I was on the right track but didn't know the correct fluid capacity held in the transmission oil pan. The owner's manual stated the total transmission oil capacity to be 7.5 quarts but there was no data on the drain-and-fill quantity. After searching the internet, a company called Amsoil had listed the drain-and-fill amount to be 4.2 quarts. So instead of draining the oil from the oil pan drain bolt (which was some weird 5/16" 4 point hole bolt), I disconnected the ATF supply hose leading from the transmission to the radiator, attached a make shift hose to the transmission supply port and ran the hose into an empty 1 gallon container with 1 quart level marks. Afterwards, I started the car and let the transmission pump the ATF into the container until it ran dry. I estimated that approximately .2 quarts would remain in the bottom of the oil pan. Using my 3 quart capacity ATF fluid pressure pump, I injected (with around 20 psi of pressure) 4 quarts of new ATF via the ATF line previously disconnected from the radiator. After re-connecting the line back to the transmission and taking the car for a test drive, the transmission was working and shifting flawlessly!
The transmission fluid transfer pump used in the video is made by OEM Tools. The 3 quart container is pressurized via the hand pump and the ATF fluid released and injected by opening the shut off valve. I first used this years ago on a VW Passat that was dip stick free with no side fill port. I injected the fluid though a fluid level tube in the center of the drain plug; a very tedious way to service transmission fluid. Since then, just about all new cars have adopted this design. It seems obvious that the car manufacturers don't want you to service your transmission or force you to bring it to the dealer.
