Transmission cooler after radiator

[camlex]

Hello,


I have 97 Camry V6 (1MZFE)
If you open the hood and standing in front of engine. You see two lines from transmission to radiator. One is left side and other is right side.

I like to put cooler, but first I like to radiator and then go to cooler and then return to transmission.



What I am trying find is which side(Left or Right) is bring fluid and which side (Left or Right) is taking back?



Thanks in advance.

hmmm....well, first of all....that doesn't go into the transmission....


a tranny cooler is basically an oil cooler....
whereas a radiator runs anti-freeze+water...

the tranny cooler can be mounted in front, or behind the rad, depending on the way the rad is mounted on a specific car

eye8, iirc the stock tranny cooler is attached to the tranny.
you can check this by looking up camry radiators (go to a shop), one of the first questions they'll ask is "transmission type?"
...and the tranny cooler does not run coolant but tranny fluid.



For the record though, bypassing the stock tranny cooler is best.

IIRC the left hose is the outlet from the tranny. Right hose is the inlet.

If you look at the front of the tranny, one of the hoses is higher up then the other. The one thats higher up is the outlet (to radiator). And the lower one is the inlet (from radiator back to tranny).

There is no up and down. Both are at same level. but left one has rubber insulation where right don't.

I think you are right . if you standing in front of engine, Left is comming out from tranny and right is going back to tranny.
Thank you.

The tranny cooler is built in to the radiator, I believe left is from tranny and right is going back to tranny.

The stock automatic cooler is nothing more than a tube running into the radiator core from one side to the other and then doubles back. It dissapates heat while immersed in radiator coolant.

An aux cooler would run downstream of that.

You guys got to be right cause thats the way I got my external tran cooler hooked up.
Time will tell how much it helps, but I feel safer with it.

maybe I should take another (closer) look sometime....

I meant where the hoses come out of the tranny. One of them is lower then the other.

You can see it in the picture below:





I suggest getting a tranny cooler with stacked plate (bar & plate) construction.

The tube & fin design is not as good as a stacked plate design. Theres less surface area and more pressure drop.


B&M makes tranny coolers with stacked plate construction.

Please help me.

CAMLEX,
I would say you never know until you disconnect the hose and run the engine to see. I found the left hose is outlet from tranny and right one is inlet to tranny in my 3vz-fe. But when I serviced my friend's 1mz-fe, I found the connection was reversed.

So I would suggest you disconnect one hose, attach same size hose to the tranny, put both hoses to the bottle, run the engine very briefly (< 5 sec), and see which is which.

is it all 1mzfe should same?

So right is outlet from transmissin and left is inlet to transmission.

THanks,,
