Installing Transmission Cooler - Please check my understanding

Did a quite some research and I think this is the way the trans lines are supposed to go. Using my very limited artistic skills made the diagrams in hopes that it makes sense and that I am thinking this though correctly. From my understanding, the output from the trans goes to the top of the existing radiator, then from the bottom of the radiator to the top of the trans cooler, and finally bottom of trans cooler back to the transmission itself. This look right?

For refence, this is the cooler I am getting. https://www.amazon.com/dp/B000C3DDEA/?coliid=I2CIOQ3RT8RPV9&colid=2W0MVBHBHCWD7

 

I have a dumb question, sorry.

May I ask what is your transmission temperature for you to decide to install a transmission cooler? Have a pic of the high temperature on your use?

 

You don't have to have high temps to warrant a cooler. A trans cooler is not only going to help stabilize and maintain a more consistent temp but it's also going to increase the fluid capacity of the system.

Many 4Runners also came from the factory with an additional, external trans cooler. Mine did and I have since changed to a much larger aftermarket trans cooler and made the OEM trans cooler into a power steering cooler.

 

Honestly, I am not "fixing" anything, I just like the idea of having better trans cooling especially when its 100+ in Texas and there is a lot of stop and go traffic. For me its cheap insurance.

 

Your diagram looks good. That's essentially how the factory does it.

 

I live in Tucson and see 110+ in the summers here. This is the first trans cooler I used and have since switched to a slightly larger one. Stacked plate coolers like these are generally a little better and more durable than the Hayden style coolers.

This is the larger one I'm running now, along with a PML aluminum trans pan.

+ may be helpful. The bypass is b/c the fluid can actually be too cool on occasion.

 

Anyone observing higher transmissions temperature with a full skid plates installed.

Pretty impressed with the cooling ability of the stock system based on my scangauge stats.
