1997 e4od 4x4 questions

[res0wc18]

so guys with the stock cooler and the summer heat i am seeing 170 degree tranny temps when im not moving. Moving it never goes above 160.

My questions are should i ditch the stock cooler and get the tru cool 4739 with the bypass valve so i don't over cool the tranny in the winter or?

Also what should the pressure be coming back from the stock cooler? Im going to install a Donaldson tranny filter setup and want to know what pressure gauge i should get with it.

The stock cooler is rated at a measly 9K, the weight of our unloaded truck.
I have the Tru Cool LPD 4590 and see 70*F over ambient temps. Never had an overheating issue since.

you're not going to "overcool" the transmission..
get a bigger cooler.

"not going to over cool it"

i thought, and can swear that ive heard that you can over cool it? What about the winter? I have no thermal bypass for the cooler?

Your tranny fluid is taking a trip through the radiator first right? That should put your tranny fluid temp at + or - 200 degrees prior to hitting your cooler right..... thats summer or winter.

yeah mike that is correct. The stock cooler is in the radiator isn't it?

Anyone have some pictures of the stock cooler setup?
