Got my cooler today and a few questions.
Where are you putting them? Under the bed? This one has the fan and temp switch.
Are you taking it out of the hot out of trans or return into the trans.
I'm leaning towards putting it in the return line.

 

I don't know about where to put it. But I'd run the extra cooler after the factory cooler. So it goes: tranny -> factory cooler -> B&M cooler -> tranny.

This way you get additional cooling on top of the factory cooling system. If you do the B&M cooler before the factory cooler, you might be heating the oil back up again before it goes back into the tranny because the coolant in the factory cooler might be hotter than the fluid coming out of the B&M cooler.

Dat's zactly whut i thought too.

Careful i think we are all being brain washed to think alike on this site!

 

I used two of them, one with out a fan in place of the factory air/oil cooler in front of the rad and one with the fan under the bed. Routing goes - hot out of the trans to the stock water to oil cooler (heat exchanger) then to the one in front of the rad then to the under bed fan mounted one then back to the trans. The nice thing about these coolers (manufactured by Long ) is they have the Low Pressure Drop feature that allows most of the cold fluid to bypass the cooler to aid in faster warm-up times. It is very important to insure you use a -8 or larger hose if you are running back to the bed so as not to restrict the fluid flow too much.

 

Keep in mind that there are many documented cases of high trans temps causing ENGINE overheating because the tranny fluid heats the coolant!

If you have a stock converter and tow heavy, you may want to seriously consider putting the B&M BEFORE the stock cooler.

This takes out some heat before it ever sees the front end of the truck, put is also keeps the fluid temps from getting too cold, which can prevent moisture from burning off like it should. That said, it's not likely that you're "overcooling" by putting it AFTER the stock cooler.
