Silver Bullet,

I can't get enough of what I'm seeing!

Looking to get rid of my heat exchanger in the worst way and go the radiator setup up front like this. I'm regularly running in the 210-220* range and this is waaay to hot! Your 150*-175* sounds gold. I was looking at the Mishimoto Raptor upgrade (is it PnP?) or go with a Hayden unit that I've used in the past (have built in tstat bypass). Can you detail more of what you did around the heat exchanger (pics?). Did you just disconnect the trans lines to the exchanger and attach the trans hose to them with clamps? What is the hose I.D.? 1/2"?

You say you removed the heat exchanger, what did you do to cap off the coolant lines, or did you just splice the return/feed lines?

Much appreciated!

Hilly,

10R80, PBH cooler adapter bracket at the bottom.

My Ford mechanic builds race cars, does all the 3.5 VCT’s, & mustang supercharger installs & enjoys doing custom work.

We towed today & ECT’s were 190-210 200-210 was really getting after through a steep hilly section & pulling fourth & fifth gear. Tranny ran 140-180 (around 150, flat towing around 70 mph (est. 8,000#).

How did we do it:

We just removed the ford trans hx & all the coolant lines to & from the engine to the faux trans cooler (hx).

Think about this:
the way ford has it set up, your trans can only get as cool as whatever your ECT is running ‍♂️

I went over to Parker-Hannifin-custom hose-shop & got 2 lines made & gave them to my mechanic.

I can only assume he somehow took care of the original coolant lines going back & forth to the faux cooler (hx)—(it’s in my basement or garage)

Almost forgot: running a mishimoto F150 radiator & just switch to a

REISCHE 170*, which made a very nice improvement this spring over the 180* I was running, last year (stock is 190*)​

So I started off this weekend with getting the Mishimoto cooler installed as well as running the lines down to where I can run them back to the transmission. Since I’m removing the HX, I think an easy way to run the lines is to repurpose the coolant lines to the HX. Going to flush them out, ordered 5/8 lines to adapt to the coolant hard lines, and run them to tie into. I got overzealous with doing the cooler install and didn’t take pictures. I going to try to do this on my own if I have the patience and time. I figured at this point I can still take to a trans shop and have them do this without charging an arm and a leg.

If I do on my own, I’ll try to document for others to follow.

Gotta say before I went through all that I'd be trying to locate a double deep trans pan for more fluid capacity. If that is viable.

There is a deeper aluminum trans pan out there. Someone posted about it somewhere in this forum.

Man if anyone has more details on that trans cooler, like part numbers for everything I would really like to do that! The engine oil cooler would be nice too.
