Trans coolers...
#11
The B&M plate type cooler are much more efficient than the tube and fin design.
I would hit the B&M thermostatically controlled fan cooled unit.
An ideal temp for hydraulic systems is 130 F.
160 F is an upper limit but still acceptable.

This is mine:

"Tru-Cool" self regulating coolers - Thick or thin, it'* the oil that regulates the cooler. That'* the principle behind the revolutionary new TRU-COOL SR series of self regulating transmission oil coolers. Thicker oil that is below the ideal operating temperature by-passes the cooler through the upper two plates. When the temperature rises, it becomes thin enough to pass through the entire cooler and receive TRU-COOL'* superior heat transfer efficiency. Automatically.

Word play guys.
Thermostatically controlled etc. Sorry..I meant that it should regulate the temperature. Meaning something should keep it from being cooled until it reaches a minimum acceptable temperature. like your thermostat in your car.
My feelings are that if you put that huge cooler on your car and in the winter the transmission does not reach a miniumu acceptable temp there may be issues from running too cold. I do not understand the 95 PCM well...and do not know if it monitors trans temp. Merely voicing my concerns that the transmission fluid may stay overly thick in the winter months and this may overwork the pump.
I monitored my 97'* trans temps last night to get more information on this topic. I have an add on GM factory cooler (and the cooler also built into the radiator) and my temps in 40F-50F degree weather did not fall below 130F and would not rise above 160F. There were spirited highway sprints and times of sitting still. This cooler has been on all winter and did not cause an issue of running too cool... however it is small in comparision to the ones you are both looking at, and a point to note is that my 4T65 is different than your 4T60....this may make the comparison null.

I will add that the 94-95 PCM does monitor Tranny temps, and if it gets too hot it will go into limp home mode

Don, define "Limp home mode" please? When my transmission decided it wanted to be interred in the nearest junkyard (on the way to a junkyard no less), it gave me no "limp home" warning or mode.
I find it relevant because I was told primary failure was the trans pump and that the rest of the tranny literally boiled itself to death.

You have one don't you?
And the trans does not warn you... Also depends on weather or not the tranny temp sensor had any fluid to sense...
When the pump went you mush have fried the clutch packs

I don't remember.
I'll look up the information regarding what the transmission does when it gets too hot tonight and post it here since its relevant to the thread.
