Trans cooler help

I am installing a bigger trans cooler in the F350 and need some help on routing the lines. They were not routed through the radiator so I would like to go through the radiator and the cooler. Thanks in advance.

Route from the front of the trans to the radiator cooler, then to the aux cooler that you're installing, then to the rear of the transmission.

Not a bad idea to use larger lines. A bit more work, but it's not that expensive to cobble up your own.

You should also use a cooler that has one larger tube in it so trans fluid can flow in -20 weather.

Get the 4R100 bypass and get the 6.0 trans cooler if you really want to go all out. You will not have to worry about flow at -20

But why would I want to go out at -20F?
