I will be installing my fuddle 3200 and B&M cooler this evening. I figured I should go ahead and use the stock radiator cooler then go into my new cooler. I have head you should just completely bypass your radiator. That doesn't make since to me. Any opinions?
Thanks

I didn't bypass the radiator when I put mine in.

i didn't either.

i would recommend having fluid flow to the radiator first then to the external cooler and back to the transmission.

the reason that sometimes (when you install a new transmission especially) its recommended to install a new cooler and bypass the old one is to insure plenty of cooler flow.

I bypass mine i figured the trans runs cooler than the engine anyway why run it into a hot radiator when it may gain some heat. my trans stays in the 170s at all times, the engine is anyplace from 180 to 200. Thats just me somone else may think diff

thanks for all the info

bypassed mine.
