Over Heating Transimission System

[ZiadKiwan]

Hello Guys,

i have a jeep liberty 2003 V6 3.7L facing an overheating problem in transmission system, after some time of driving the car generate a lot of heat that you can feel near the front seat doors while leaving the car, it starts to make kicking sound (a hit sound while moving between transmission speeds) and it torque die, especially while going up the hills.

while checking the radiators, i noticed that the main radiator (Water Radiator), isn't linked with pipes to the transmission system, the hoses plugs for the transmission cooling on the radiator are available but they are not linked, the transmission cools through a small radiator (Air Radiator) located in front at the bottom of the main radiator, the jeep got imported from Canada, Canada have very low temps compering to us as the lowest temp here may reach 0C to -5C and this is only for few weeks, the average temp is 10C-20C.

please note that the transmission oil overheating signal doesn't light on the dash board.

what I'm planing to do is to cut the hose that flows back the transmission oil from the air radiator(Small one), then plug it to the main radiator (water cooling) and then link it back to the cut hose.

this picture will explain you what i'm talking about:

what do you think guys ? is it the most suitable solution ? what do you suggest ?
thank you, and sorry for the long post!

Your post is a little hard to understand. Not sure what 'torque die' is...

The way your Jeep is right now is how it came from the factory. Yes, you can plumb the radiator cooler in series with the air to fluid cooler.

You could also install a mechanical clutched fan to help the electric fan.

Either way, your transmission shouldnt be overheating. Maybe on a 100F day while pulling a trailer slowly up a hill.

I have 93,000 on my 04 liberty and Ive never overheated anything with the setup like you have.

Hello Jeep Jeepster,
i mean by torque die, that my jeep is loosing its power when going up hills, i push the gas pedal but it wont respond it wont go faster it keeps loosing its speed, until 2nd transmission speed.

my transmission overheat just by driving around for 10-15 min, do you think changing the Transmission radiator will fix the problem ?

I'm lost too.
What makes you think your transmission is overheating if the transmission oil overheating signal doesn't light on the dash board?

I have had a lot of experience with transmission overheating both when towing a heavy load or while off-roading.
My problems were caused by a muddy radiator and failing clutch or electric radiator fans.
I have the Mopar trailer package.

Well from my point of view is that, the oil is overheating, but not till the level that makes the computer emit this warn, I think after 2-3 hours of driving the light will turn on, but i never drove that long since i bought it, the clutch and the fan are working fine, i cleaned the radiator 1 week ago, but the problem still persist, I'm trying to find the most suitable solution to fix it.

I happen to know that the idiot light does not come on until 240F meaning it does not come on until your transmission is completely and severely over heated. An overheat situation occurs at transmission temps over 200F. I you are worried about transmission temps, just add a transmission temperature gauge to the top transmission cooler line. I did that and found out my libby was over heating and added a second transmission cooler.

You have an aftermarket radiator, that's why you have a ****** cooler built in. If you're worried about transmission overheating, add the radiator cooler into the circuit.

Exactly, Okay thank you!
