Picked up from pan > Trans oil pump > Optional Supplemental Cooler > Engine mounted Heat Injector > Cooler up front > Transmission
I know there's a bunch of controversy over the HE, but bypassing it dang sure knocked 50* off my temps and manually energizing the supplemental fan from the start keeps it all sane dragging 7000#.
Sure wish I could find someone locally that could diagnose what I believe is a WornSlapOut OEM torque converter... would make a replacement TC & shift kit easier to stomach than all my WAGing

I carefully traced mine (3-4 times going both ways) and found what appeared to be OEM plumbing of:

I've got an 01' sec gen truck. I put a 12 inch permacool trans cooler with a 10 inch fan on mine. Its tucked in the front bumper, not sure if that will work with a 1st gen bumper. I went with a switch in the cab for the fan.

Must have been the dyslexia(?), cause I pooched this pretty good!
ACTUAL FLOW: Picked up from pan > Trans oil pump > Engine mounted Heat Injector > Optional Supplemental Cooler > Cooler up front > Transmission
Once the HE was bypassed, the temps dropped too reasonable marks with just the 2 air-oil coolers.
Also, my "cut off @ 240-270* switch" was yanked to place the tranny temp sender... no regrets since that scenario would leave you with a nuclear grade meltdown *if* it actually worked.

Hey folks,
I'm fixing to install an auxiliary transmission fluid cooler and was wondering how and where folks were putting them. The FSM doesn't seem to address it at all.
Can anyone post images of their mess?
I expect to have to fabricate a bracket assembly to hold my cooler in place and want to be sure to include considerations such as air-flow, hose routing, truck frame attachment, etc.
Thanks.

The Superduty cooler installation also installed an "H" pipe between supply and return before the cooler - when the fluid in the lines is cool it bypasses the cooler and returns to the trans.

Again, thanks for the replies folks.
I've received the cooler. It's of the "Plate And Fin" design and as such, offers substantially more in fluid cooling when compared to the more common "Tube And Fin" type of the same foot print.
The actual cooler is 11" x 8 1/4" x 2" excluding the fan and shroud and uses AN8 fittings.
I've just about decided to mount it right there in front of the fuel tank as I don't have enough 1/2" "Socketless" hose on hand to reach the OEM location (the hose is expensive!).
DBF, Ive seen those thermostats advertised http://store.summitracing.com/partde...5&autoview=sku but wondered how reliable they are as well as to weather I need one in NC.

The "H" fitting to the left is the DC cooler bypass. It depends on the idea that cold fluid in the cooler to the left will present a high fluid resistance and force most of the fluid through the cross-bar of the "H". When it warms up, most will flow straight through one side of the "H" to the cooler and back through the other side of the "H".
I don't know where you'd find one other than a junkyard.
I wanted to change it to the one you pointed out, but I couldn't figure out how to flush the whole system from up front - it would go through the cross-bar and never flush the cooler. Guess I'll have to make my own.
I have two sets of trans-cooling pictures in:

I wonder if that "H" affair is what's going on with the OEM trans fluid plumbing up front, right there before the little radiator. It seems I recall a couple of plastic things (in the shape of an H IIRC) oddly plumbed there.
