yep i got the large unit and am going to just go thru it..it has the thermo by pass and all on it already.

 

manufacturers and trans cooler makers rec running the lines thru the rad first and then to the a/m cooler and then back to the trans.
why?
one - it provides a 2 stage cooling drop - once thru the rad -cools off some and then thru the cooler - drops the temp even more
two - for veh's in the north - it also will warm the trans fluid to proper temp when it is very cold - really really cold trans fluid is a bad idea.
here is a quote from the B&M website
The Super-Coolers intended for automatic transmission fluid also offer an additional feature known as Low Pressure Drop (LPD). The coolers assembled with hose barb ends include a unique bypass feature allowing a controlled amount of ATF to bypass the stacked plate core when the fluid is cold. This is beneficial in cold climate areas to guard against lube system failure. Controlled by viscosity, fluid is returned directly to the lube circuit through bypass openings in the stacked plate core. As the temperature increases, more ATF is directed through the core. This highly efficient design combines improved protection against lube system failure with the required levels of optimal heat transfer.

 

im running the stock one in the Rad and a Perma-cool HD.

 

Heres mine its pretty big I guess

i ordered a b&m supercooler rated at 24K gvw or something like that. i am going to try it in conjunction with the stocker if i can. if not, it will be ran on it's own and maybe a fan added to it.

 

Ya'll have to understand. He has to brag about the size of the tranny cooler cause it's the only thing he has to brag about.

 

Hahaha refer to my thread in the truck stop section.

 

that is a big cooler! lol

 

I am running 24k B&M's on 3 veh's
