Transmission cooler mounting

[Bigdumogre]

When you mounted yours did you have the lines and fittings facing down or up? I have seen plenty of pictures of both and about to do mine so was just wondering if there is any benefit to either decision.

Lines & fittings facing down on mine.

Facing down on mine as well..

That’s what I’m thinking since the lines are already down at the bottom why not just go straight from there. Thanks

You go, to the rad, then from the rad to the cooler, then to the transmission. SO, you
will leave the line going to the rad alone. You pull the FROM rad line, that goes back
to the trans. Then, from that rad fitting, to the cooler, then from the cooler to the
return line.

You can mount the cooler with the fittings horizontal, you will put the return line
on the top fitting.

This is just the rad with the trans cooler on the side, the Camaro is bottom.



If sideways, the RETURN line goes to the top fitting. You really don't want
fluid to drain back. Since, you may need to add some so it's where it needs
to be, the drain back will over fill the pan, and may come out the side fill/vent
plug.

Same if you mount it with the fittings facing DOWN. All that fluid can drain back into
the pan. Face them UP, or sideways and RETURN line up top. I recently changed the
fluid, and I put 7 quarts in, and it came out the fill hole. It calls for 6.7 quarts
with a pan drop and filter change. Just a heads up, if you add fluid after putting
the cooler on, it may over-flow out; since you add fluid with the engine running
with the drain level plug out...

Thanks that’s a very interesting reason to mount the fittings up or horizontally. I will be doing a jre dipstick to mine and should arrive today just to make it easier to get the level correct.

The JRE dipstick is a great add on. With my trans cooler, I bypassed the factory cooler in the radiator.

I have seen many do that and it has its advantages and disadvantages. So does going through the rad first lol. I’m gonna keep it through the rad first as a personal preference , neither is right or wrong.

Completely agree, just providing info.

Going through the rad first, stabilizes the fluid temps. With just the cooler, you would
have drastic temperature fluctuations. The majority of transmission coolers are
supplemental (AUX), meaning they are designed to aid the radiator in cooling the
vehicle's transmission fluid.

Basically:
Through the radiator cooler for faster warm ups and consistent trans temp, and then
through an external cooler to make sure fluid going back back that is a little cooler than
the engine in case the engine runs hot.

The one on my former Charger was a stand-alone, and I could watch the temperature
fluctuate when coasting. Optimal trans fluid temperature should be below 175-f.
180 to the upper 190s isn't too bad, but it should remain at a good 180 and lower.

Neither one is wrong, and based on climate too, I suppose. If you don't have
winters, then just a good external cooler is good. If you do have winters, you
need the temperature to get up quicker. Too cold temps for the trans is also not
good for it, but I would rather have that than too hot.

I installed a thermostat inline with my cooler and didn't run it through the radiator I just have to take it easy the first few miles to allow it to warm up.

I went with the thought that adding it inline with the radiator was more than the transmission pump was designed to handle. Don't know how true that is, but either scheme seems to work.

I’ve looked at your build thread a few times lol. I bought a tube that goes into the radiator stock fitting like the line does but has a hose attachment on it. Seems like a easy way to install and will be trying it soon as the weather clears up by me.

Yup, should work well!
