AOD question

BoveK · 09-01-2001, 07:04 PM

On the AOD which fitting is the outlet the upper or lower? Also, On the radiator, does the line from the outlet go to the upper fitting or the lower?
Thanks

Anyone?

AOD flow is out of the torque converter at the top fitting of the AOD and in through the lower fitting. AOD-E is the opposite. I'm not sure about the radiator, I'd have to go outside to check for sure.

The top fitting on the rad. is where the AOD pumps from. This is the press. line out of the tranny and into the TOP of the Rad. cooler.

So let me make sure i am hearing you right....The top fitting on the AOD is the outlet, and it goes to the top fitting on the radiator. Sorry if i sound dim, but i jsut want to double check

No, the oil going to the cooler goes in the bottom. A LOT of guys mistakenly put it in the top, but you need the "reservoir" effect to more effective cool the oil and stop aeration. You should be using a tranny cooler with an AOD, anyway. Otherwise you'll be rebuilding in short time. Listen to the voice of experience. Good luck.

Thanks for clarifing Capri306. I am running a external cooler in addition to going through the radiator cooler. Just out of curiosity...is it better to have the tranny go from the radiator to the cooler then back to the tranny or the cooler then the radiator?
Thanks again

I dont know how anybody can mistakenly put the fluid going in the wrong way, as the lines only fit one way, unless you force them into the wrong position on the tranny side?

I will say that Im not positive about which one is the pump output (top or bottom) and I dont have the time to look through my books to verify, but I would like to know what the "reservoir" effect is? I have considerable hydraulic experience and have never heard of this.

And it is always a good idea to run an extra tranny cooler with any automatic, but the AOD will not burn up in short order without one, so I dont I dont know where that came from?

By the way, I have mine routed into the aux. cooler by way of the bottom rad. outlet. This is why I thought the fluid went into the top of the rad. first, as is what I believe the b&m cooler instructions stated.
It makes it easier to route the lines this way(depending on where you mount your cooler, and if you want to cut the factory lines or not to facilitate installation)

So let me simplify this - it goes into the top of the rad. from the tranny, then out the bottom of the rad, then into the aux. cooler, and then back to the tranny by way of the bottom tranny line which is now connected to the cooler and not the radiater.

Capri- I have a feeling this "reservoir effect" has something to do with bleeding the system of air. Is this what you are talking about? And if so, it would seem pointless to me as the air will self bleed out of the dipstick opening.

The reason I have this question is that I have -6 steel braided lines for the tranny and dont know which way it was run(my buddy cut out the lines before I could take notice of how they were run). It is by no means a stock AOD, but regardless I was just wondering what the best way to keep the f**cker cool.
Thanks again

Like somebody siad earlier, it really doesnt matter which way you route them, so I wouldnt lose any sleep over it, so to speak. I would recommend hooking to the top of the rad, out the bottom, through the aux. cooler, back to the tranny.

You can fire up the car with the lines open and see where it flows from to determine the pressure side on the tranny. Or you could buy a book and look it up.
