Transmission cooler needed?

[elorenzof]

Good Morning,
So i am continuing my build on a 72 K10, and we have purchased a Mishimoto 3 core Aluminum Radiator. I have new steel trans lines from the TH350. My question is: do i need to install an aftermarket transmission cooler? I have a trans cooler just in case but if not needed it saves an extra step and also keeps the core support area cleaner and free of less stuff. Suggestions and comments please.

If your powertrain is pretty much stock -- and if the radiator has a built-in trans cooler -- you shouldn't need an aftermarket cooler.

If you're building a hotrod or a workhorse that will see severe duty, I would add one.

A trans cooler is never a bad idea. But like mentioned above, you might not really NEED one.

My personal opinion is if you have it install it. You never know when you may need to pull something and instead of wishing you could have pulled it and not. I would install it just for good insurance on keeping the trans temp below 200* no matter what you used it for.

So the new radiator has a built-in trans cooler?

As said with a stock motor you dont need one. A high stall torque converter and/or a high hp engine is when you need extra cooling.

the radiator has the openings for the transmisison lines going to and from the trans.

Ah, perfect! You're all set. I asked because some radiators have no provision for trans cooling -- in which case a separate cooler would be called for, even with a stock drivetrain. You are good to go!

Or when using it as a truck hauling heavy loads/towing. But, even then you don't absolutely need one. It would also depend on how heavy duty the radiator is, core count. I hauled an over the cab/10' floor camper on a C/20 350/TH350/HD radiator w/o an aux trans cooler. It never got hot and the transmission never lasted through it all and is in another truck now.

Something I feel an automatic transmission equipped truck should have is a transmission temperature gauge.

thank you all for your support.

My FiL installed a transmission oil temp gauge in front of the blank hole in the gauge dash. Seems like it could have been mounted in that spot. I'm thinking of doing that when I get some ambition.
