then the gravity feed fill hose should go directly into the side fill hole on the trans & does not take a long time at all. & when using the funnel it can be hung from the hood like "xtremewlr" shows if youre by yourself but if you have a helper it can just be held above the passenger side fender, doesnt need to be above the hood. & as i explained in my last post, using the fill hole on the trans lets the fluid gravity feed very quick, takes about 2-3 minutes to fill 2 qts.

also curious what you used the valvoline jug threads for? when filling the new fluid you just pour it into the funnel & let it gravity drain into the trans fill hole. not sure what or why you needed to make a gravity feed tank from a 2 litre bottle.

in the future, i hope anyone reading this thread reads the whole thing & sees my posts & realizes that the procedure in the initial post by the OP is NOT the correct way to do this... there is no need to use an adapter & try to splice into the tans lines, just use the bottom trans line port on the radiator, it is the output for the trans fluid. & do not fill via the trans lines, just use the fill hole in the side of the trans as its designed to be used. or the dipstick if you have a non sealed trans. the rest of the write up & comments are fine... but why make this harder than it needs to be?

The valvoline threads were from a bad idea to use the adapter from Walmart to directly connect to the valvoline bottles. Don't do this because air pressure is a thing.

Most full flush are 10 quarts or more, which the video did.

Most full flush are 10 quarts or more, which the video did. Atleast on gen 3 or others. My seinna van took 2.5-3 gallons.

Definitely an easy overall process.

Unfortunately I couldn’t get one of the fittings undone for the return line that went directly back to the transmission like I had planned. So I had to use the inlet into the radiator instead.

I have an aux trans cooler installed too, so anything I pumped into the radiator would go through there and then through the aux trans cooler mounted on the radiator before finally returning to the trans. The bottom line is, gravity wasn’t going to work for me on this project, so I had to use a hand pump.
That part ended up being a pain in the ass, hand pumping 12 qts back into the trans wasn’t a quick process...

Glad I did it though, old trans fluid wasn’t black, but it was definitely a few shades darker red than the new stuff I put in. Transmission shifts like new again.

Can’t beat the piece of mind for the next 50k or so.

Hooked my power bleeder and was done in an hour. I can definitely feel the difference, the shifting is so much smoother.
I appreciated the help from the members here.
