Some guys say no, because your radiator is supposedly hotter than your trans fluid much of the time......

Other guys say yes, because the fluid will get cooled twice.

I don't understand the inner workings of a radiator, but if it is hotter than my trans fluid I would think it would be better to bypass it and just cool through the tranny cooler only.

I am running a high stall converter with a new motor and this part is a must in my mind, I just want to know the best way to install it.

 

Its always best to run it through the radiator part first, then the auxilary cooler.

 

This just goes to show that "some guys" still don't know what they're talking about. You should ALWAYS run the coolers in series...Through the stock radiator first, and then through the auxillary cooler.

It should be run in series with radiator first, then auxilary, but it doesn't necessarily have to. It won't hurt anything if you don't. I ran mine like this;

Transmission -> radiator -> cooler -> back to trans.

Who ever said the radiator is hotter than the fluid does not know what they are talking about. They put the trans/radiator cooler there for a reason, it works.

 

Thanks. That's why I asked.
