I have 85k on my car. All recalls have been fine, all critical replacement parts have been installed, catch can, trans cooler etc. I've had no problems.
    i gotta say... GM dropped the ball when it came to the rad and tranny cooler lines.
    there is no service bulletin or recall notice for them.

    these aftermarket "fixes" yes will solve the issues, however they are not gm approved, so if by some chance you have a 07 and under warranty then you do any of these mods they void your warranty for the parts of the car that the mods are affected by.
    its like buying a hockey stick cutting it too short then trying to return it because you screwed it up.
    they designed the car, they should be liable for all common issues, especially the tranny cooler lines.
    now, mine is a 03, generally there is a 10 year statute of limitations on most legal clauses, so im sol either way.

    Re: Trans cooler lines pulled out of radiator???

    Hi,

    Had similar problem.

    My car is from 2009. Is the problem occur in this models?

    I parked my car and I smell oil.

    Look under the hood and I noticed little bit of oil in the left corner.

    I wipe it and took the car for cruising. I drove in few modes, easy driving, kick down, manual mode.

    Trans works fine. I opened hood and I haven't notice leaking.

    It is possible for temporary leaking because of high pressure (run hard from junction, spin the wheel a bit)

    Steering fluid and coolant looks good.

    Check the 2 lines at the rad. If there is fluid, the lines are leaking. No if, ands, or buts.

    Re: Trans cooler lines pulled out of radiator???

    OK,

    Today I also spent some time with my Caddy

    What I realized, that wasn't trans fluid that was coolant !!!

    But there is no leaking any more.

    But one thing. There is kind of coolant hose joint. I noticed one clamp is broken only 60% of clam cover the hose.

    I think the coolant gone there when I stopped in traffic and temperature increased. (No signal about it on dash board) So I have to replace clamps anyway.

    But is anyone can explain the coolant hoses connections? The join what I'm talking about has two hoses. One is going to the cooler second one to the plastic cover (is this thermostat?) and from the cover to the cooler.

    EDIT:

    Ok I know it is Auxiliary Water Pump mounted for LLT engines

    Re: Trans cooler lines pulled out of radiator???

    Just had the trans cooler line break on me. Just like many others I was at a red light and when it turned green the cadi wouldn't go.Stepped outside the car trans fluid every where. The radiator isn't leaking coolant.
    DO I NEED to by a new Radiator or can I just buy an external tranny cooler and refill the transmission? Thx

    Just buy a trans cooler. Literally just had this happen to me, was fortunate that nothing more severe happened. Hayden 1240 is what I went with, it has the OEM dimensions for the lines and everything. Also get a trans filter kit. You'll need a fluid pump to put tranny fluid back in. GL man, message me if you need anything. Literally just did this yesterday.

    Ok thx for the feedback. I have a fluid pump but how do you refill the transmission? I pumped about 2qts and it started overflowing. The car is off and I know I lost more than 2qts. Does the car HAVE to be on?

    You can add me to the list however mine broke while trying to reinstall the line after flushing the tranny and not on the road. So I already have it up on jackstands. I guess we saved the environment from a bunch of ATF on the road and saved me a tow. I'm thinking about doing the external cooler instead of just replacing the radiator.

    I'm sorry to hear that. I'm still shocked that it has happened to this many people! Hasn't Cadillac issued a recall on this? It seems dangerous to spew ATF all over and leave people stranded. I had my elderly grandfather with me when it happened.

    Mine failed internally, no sign of a leak. Therefore it filled the tranny with coolant, the engine with Dexron.

    Ouch, that would be the worst kind of failure! Did it destroy the transmission?

    Oh ya. It probably happened gradually, as there was no indication, so it was mixing unbeknownst to me, until I noticed a slight overheating, then it started slipping.
    I opted for a reman trans. Thousands of $$$

    Re: Trans cooler lines pulled out of radiator???

    Just happened to me. 2006 with 112K miles. On the passenger side, trani fitting broke clean from behind the Hex nut. Looks very rusty on the rear of that nut. It also was leaking anti-freeze from the same general area. Fluid pissing all over the exhaust caused quite the smoke show. I got the car parked, but not before the car stopped moving on its own. I shut it off immediately after is started to rev and go no where. What's the chances of the trani being permanently damaged from lack of fluid? I'll replace the rad tomorrow
