Aftermarket preference
On '05 6.0 which brand OIL/EGR cooler is recommended for OEM replacement? When monitoring with EDGE Evolution is trans. fluid temp number correct, if so what is normal laden/unladen range? Which internet parts source do you recommend?
Thanks,
Bill

Trans normal temps
Normal=150-195f
severe=195-200f
alarm=220f
From Bismics spread sheets:
As for the "Factory" transmission temp gauge, it is a glorified "idiot" light as its response is severely dampened. The panel gage will show the temp as fully warmed up at 50 *F. Between 100-220F the needle will remain in the same position on the gauge. At 230F it will move up slightly to the middle of the normal range. At 250F it will move to Yellow. The gauge moves to red at 280. This is supported on page 36 of the OBDII Theory and Operations manual. The tow/haul light will flash at 275.
Over 220 is really too hot for continuous service - most likely something is not right when you see temps continuously this high. Never exceed 250 for more than 30 minutes for reasons below.
Mark Kovalsky (former Ford tranny engineer) says the fluid can get to 300 for a SHORT time w/o any seal damage (however a measured temp of 250 could actually mean that some areas and parts may already be as high as 300 - normal tranny fluid is good to 300 or so, but your tranny isn't!).
One reference I saw stated that seals begin to harden past 240 or 250, Mark K. disagrees w/ this as stated above.

Go with BPD for the egr cooler. I would just stick with the stock oil cooler, or go with the bullet proff one.
The stock tranny gauge is crap, but the sender is pretty good. You can stick with your edge for monitoring the temps.
