The top one is the PS hose, the bottom is the transmission hose.

So line RED = PS Cooler

Line GREEN = Trans cooler

You should try and follow the green line to be 100% sure. I've heard of people having it be a different way, however that is the way it should have come from the factory. One with fins is the PS, one without is trans.

 

Hello Breeves002

Question 1> Is this cooler the same as radiator? Because I heard that there is a special connector between the transmission hose with the radiator that can only be removed with a special fitting. Or the cooler is different from radiator?

Question 2> Is there a leak on the transmission GREEN line or it is normal b/c I just got a transmission pan drop service.

Thank you

 

The radiator is also the transmission cooler. Some people add a cooler in line to get a better job done. If it is leaking around the hoses where it was worked on check to see if clamp is tight. There is a special tool for removing the trans cooler line from radiator. No leaks are normal!!

 

1. The trans cooler and radiator are very different. Radiator is cooling the engine coolant. I'm not 100% sure how the trans cooling system works though, but there may be something I'm missing.

2. There should be no leak. You may need to replace the hose, or the hose clamp. Make sure you check your ATF level. It isn't good to run out.

P.S. Call me Sam!

 

Transaxle Cooling

All vehicles are equipped with an integral fluid cooler and a combination fluid cooler. The integral transmission fluid cooler is contained inside of the radiator outlet tank and cannot be repaired separately. The combination fluid cooler is an external cooler for the transaxle and the power steering system. The combination cooler is mounted on the bottom of the radiator support. In operation, transmission fluid travels from the transaxle to the integral transmission fluid cooler, to the combination fluid cooler, then back to the transaxle. The integral transmission fluid cooler transfers heat from the transmission fluid to the engine coolant. The combination fluid cooler transfers heat from the transmission fluid to outside air.
