Hi Art!

I see we are watching yet another thread talking about automatic transmission fluid lines.
Sharing the love we are!

I finally got around to putting in my fitting with a Side Port and Flare Cap.
Very neatly on the top line to the radiator cooler fitting.
Shoved the line backwards just over an inch by hand. Lots of length from the bottom up!

I can now draw off fluid, whenever I want, instead of dropping the pan.
The fluid can be exchanged along with the engine oil intervals.
Actually, Easier than doing the engine oil!

I added a female flare fitting and 1/4” ball valve with the tubing like you suggested.
So the fluid goes right into a jug for recycling.
No mess!
The clear tubing let’s me see the change in color progress.
I did one gallon, a quart at a time, as I was afraid to suck air from the sump?
I don’t know much about automatics running the sumps too low?
But now I have done it once, I’m thinking, maybe two or three can probably come out in one shot. Just watch bubbles and just turn off the valve!

I never shut the engine down, just let it all circulate.
It shifted more smoothly right away.
Not that it was that bad @30K, but now it’s going to be a perpetual thing!
This is going to make my manual shifters cars very jealous! (:-)
Yes, it can happen they are man made creatures with each their own individual characteristics! (:-)

If this thread owner wants to install a whole new line he might want these same features?
I came up with a tee fitting that looks like this:

Optional fitting to that ball valve was this:

I didn’t buy any from them above, but from a local industrial contractor, that sell and repairs pressure washers.
This was an old time man cave of a place I found! A niche of a joint!
Crowded to the hilt with stuff but with up to date prices, you betcha! (:(
Last years small business handouts sure stocked them up ahead of inflation!
Talking about back room dealings for survival, it’s happening in parts houses!

I paid more for it than what was listed for those above!
You start looking at minimum orders and shipping from these industrial places, you might as well be ready to grab the belt holding up your pants!
Don’t even think about Stainless Steel. Unbelievable differences!
Your right about McMaster-Carr even 12 years ago!
I looked at hand flare tools tonight and their not taking any prisoners with other businesses either!
Chain reactions!
Our cars are worth ever so much more now for simplicity!

My deal was directly into my hands from some cabinet drawers.
Altogether, I spent $38 with taxes but hey, it was an adventurous birthday present to myself!

Sort of fun, tracking down the right place to get FITTED up! (:-)
