Needs some help in this area. Before I buy my radiator, not sure wether to run an external cooler or a built in. Not sure what the limitations are of a built in cooler. I'm running a 10" 3500 stall th400. Any help thanks

Years ago I asked the Teck guy at B&M transmissions if I needed additional cooling (allready had cooling for trans in radiator) when I stepped up my stall speed to 2800. He said that whenever you increase stall speed that they highly recommend you also install an additional cooler in series with the radiator cooler. Hope this helps,
John

get as big as you can afford.. heat is the destroyer of transmissions...

in my book the plate and fin type are the best at cooling..

From the TCI Transmission web site...... "Unless operating in an environment where the outside temperature is below 0°F, you should cap off the radiator cooler line openings and run your cooler lines directly to a new cooler mounted in front of the radiator. This allows the transmission to have its own cooling system and doesn't allow the engine water temperature to heat the fluid." http://www.tciauto.com/Products/TechInfo/FAQ.asp#1 A high stall converter has no problem warming the fluid up to operating temps, so I see no benefit to running thru the engine radiator.
