From the pics I've seen online its called a heat exchanger. Does the trans fluid run into the actual radiator, or just make a loop at the exchanger itself? I'm just curious so I can have tranny fluid on hand as well.

And thanks, Trader.. But I'm on the the next problem. Which it always seems like there is one.

Alright. Just if you guys were wondering. The trans fluid does not cycle through the radiator, but just makes the look at the exchanger itself.

It looks like a simple repair. I got the special "X-Rings" to do it. hopefully the radiator isn't cracked or anything crazy.

With the X5, if it isn't broken yet, it will be in the near future. Not really, but it does seem that way...

Tell me about it. This is the most fragile vehicle I've ever owned... And I've had a lot.

I sure like it when it's all working, but that seems rare. I thought about trading it off for a newer one.. But I'm afraid the cycle would start all over...
