I use a drill operated fluid pump drawing from a SECURE bucket of fluid, and fish tank clear tubing to deliver it.

making the source of the fluid stable and not wanting to spill/fall over was the important part.

I've schedul a repair... But it's a while away.

A few days ago, I check the ATF level and found it was about 1/3 of inch under the min. So, since I didn't move the car. The last thing I want is a trashed transmition.

However, I still need to bring it to the shop for repair.
So, I decided to fill back the ATF tank.

Is it the worst placed tank cap or is there worst somewhere else?
I manage to fill back the tank (While the car being in neutral to have the right reading)
But while I put around 2L of oil in the tank, I probably also put 500ml on the floor and another 100-200 ml on myself. Is there a mysterious secret way to refilling that tank or you really need to manually pump oil in it from under the car by the little space left between the tank top of the car? They could have made a little openning in the car to refill that.

Any tips to do it clean, so I can learn for the next time...
i also have a small leak from the TC but only need to top up so i just pour to a smaller bottle and squeeze the fluid, make sure to remove the screen for a better flow. let me know after your repair to see what they change and how much?
Thank, Barry

I found a plunger pump that threads onto the top of a 1 gallon ATF jug at my local autoparts store for like 7 bucks. I added a longer hose to it to it would reach the transmission reservoir. I sit beside the car and fill the transmission, couldn't be any easier!

It looks just like this one on Amazon.

I use a garden sprayer. Works fantastic! can fill 3 or four litres at a go. Just take off the atomizer and bend the end a little more.

Bonus is the hard plastic makes it easy to hold into the reservoir. Also the pump limits the amount of flow and it works out perfectly to allow the strainer to stay in place (important) and not run over. It also makes it so you can reach in and fill without jack stands.

I wound up changing my ATF today with the Harbor Freight pump.

It worked pretty well. I kept the strainer in place so I had to push the plunger in VERY slowly. Too fast and fluid would overflow. I had to use a twist tie to hold the hose in place so it would stay in the reservoir.
