When to upgrade to an external cooler?

[karolko]

I am sure this question has been asked before, and i have read that with normal and moderately modified vehicles, that the regualr internal cooler works jsut fine with our cars BUT...

What about vehicles that are beaten up ALOT. My car is a strret vehicle, but pushing alot of power, I have a aluminum radiator from Redc5, but will it be enough. I guess i can try it out for myself, but why not ask to see what you guys have concluded from your trials.,


Thanks alot for the insight,

Adrian

Heat is a number one problem with auto transmissions. I add a cooler the moment I get my cars since I don't baby them. Even my stock 84T got a 19,000gvw cooler. Later on I added a 2800 12" stall after building the trans.

I have a big hayden, I think around 28,000 and the temps dont go above 200. May be overkill but I've had trans go south from heat.
