It might be overkill, but I have that exact one installed in my coach. The radiator is completely bypassed. During my trip to KS in 110* heat it kept the engine running at normal temp. On the interstate it would run below the "normal" mark from before the install and only climb to the "normal" mark while climbing the hills. The fan clutch is hardly on anymore.
I like the added volume as well (about a quart) of the 16 pass core and the fan is reversible. My install is angled under the front battery tray and shows the lower edge about 2 inches below the body.

My consideration was to remove the 300* F trans fluid from the radiator and to have the available cooler used for the engine oil to be cooled if I need it. The Derale cooler does a great job. I have used other sizes in cars with great results.
Rob,
In your flow chart below I would only eliminate the run to the radiator. The rest is part of my total upgrade as soon as I can can get to it. A 16 turn cooler will get you all you need. Mine runs mostly in the stop and go period in town. On highway runs, I seem to hear it only on steep hills. It has a 180* ON/170* OFF automatic thermostat.
<I reckon the ideal flow path for a switch pitch transmission would be:
1) upgrade the 5/16" transmission to radiator lines to 3/8"
2) flow from the transmission to aluminum radiator
3) flow from the aluminum radiator to this cooler
4) flow from the cooler to a remote transmission oil filter with a temp
sensor in the housing
5) flow from the remote transmission oil filter back to the transmission>
The same cooler can and has been used as an engine oil cooler with the same great results.

Rob,
As you know, we have the big Caddy in our 77. We also have a
switch-pitch by Manny and an aluminum radiator. When I installed
the radiator, I ran 3/8" lines over the bellhousing and up the RH
frame
rails. I also have a Ragusa pan on the tranny.
Now, coming home from the GMCMI gathering at Montgomery, Texas
we stopped in Camp WalMart just west of Little Rock, Arkansas.
In the
morning we used the switch-pitch pulling out of a low parking
lot.
It never went back into low stall. After a bunch of twiddling,
we decided
the problem was inside. We called Manny and he said to drive on
and
watch the temp gauge. If it comes up, STOP.
We drove 800 miles at 60 mph and the temp gauge never moved from
it's normal location. I told Gene Dotson he was my hero for
life.
Of course, after that, I hooked up my tranny temp gauge. Then I
found
that my pan temp runs about 130 degrees on flat ground. That's my
experience.

Nick,
My current flow path is:
1) 5/16" OEM line from transmission to aluminum radiator
2) from the aluminum radiator to current external cooler
3) from the current external cooler back to the transmission
I have a Digi Panel that has a sensor under one of the trans pan
bolts and a
remote oil temp sensor in the transmission pan which feeds a
separate gage.
The Digi Panel sits at 160°F - 175°F and the gage tracks the
same. I do not
tow. The problem is a switch pitch transmission increases the
heat output a
great deal. I DO not have any direct experience with this but a
number of
people that have them have noted this and every article I've read
on them
says the same thing. Perhaps someone that has a switch pitch can
provide a
better insight as to the temperature output. I would retain the
two coolers
to maximize the amount of cooling available. When they were
installed in
Toronados the switch pitch function would actuate at full
throttle and had
circuitry that would limit the amount of time it was allowed to
stay
engaged. It was meant to provide extra torque when passing a
vehicle. I
think the fan would be a helpful feature on hot days.
I have a gage to monitor engine oil temp as well but have yet to
install the
sensor for it. I have yet to decide whether to install the sensor
in the
lines that go to or come from the engine oil cooler. I am
thinking of
installing two sensors one in each line or one in the line to the
cooler and
one in the oil pan and set it up with a switch so I could read
both temps.

I had the same problem with my transmission temperature. I replaced the gauge and pickup twice before I realized that my trans oil temp in the pan is below the bottom of the gauge. My Stewart Warner gauge starts at 150. Shooting the Ragusa pan with an IR gun when stopping after a long run showed the pan at 120.
I run a 180 degree thermostat, a Ragusa aluminum trans pan, and an additional trans oil cooler up front.

Gary,
No remote trans cooler? Just the one in the aluminum radiator?
It appears that the 3/8" lines make a big difference in the flow rate to the
trans oil cooler.

Rob,
No remote cooler. Don't forget the switch-pitch is much tighter
in
low stall. And, we seldom use high stall. Seems kinda'
redundant.

I you read here, you will see switch pitch are big heat generators
when they are engaged.
