you don't need a pump kit to fill the trans. A long neck funnel is enough, I used this one from AutoZone (Link here) and it perfectly fits into the dipstick tube. with this funnel there's no need to remove the air box, just the ECU cover and that's it. it reaches the dipstick tube with no problems.

 

I wish this thread was started about a month ago!

I just did a transmission oil flush and had to rig up some funnel/hose contraption in my shop to add oil to my transmission. I had a perfect funnel for many years that worked great for this job the last time I did it (about 40k miles ago) but it disappeared in my shop. I wasn't satisfied with anything I found on Amazon or in my local auto parts shops, so I was forced to be creative!

Thanks for the link!

 

BTW, trans dipstick tube inside diameter is 1/2 inch.

 

Excellent, thank you! I have a very similar funnel and will go this route instead.

By chance do you recall how much fluid you added back in? I'm thinking I'll start with 3 ish quarts and then check the dipstick before adding more.

 

Yes, that's the correct fluid. It's the same as Toyota Type T-IV, which is usually cheaper. I paid around $7.50/qt at my local dealer last time I drained and refilled.

 

Credits to @Facusan for advising me on the best way to get to this sucker. You will need a long neck funnel of some sort as mentioned above. Once you pull the ECU cover off, here is how it looks like from the bottom of the car:
