If there are lines coming from the transmission to the radiator, it has a cooler in the radiator. If there are lines from the transmission to an external heat exchanger, that would be an auxiliary cooler.
Strong possibility of a blown head gasket. Either do not drive it or driver very slowly and carefully to get it checked. You dont have a blown head gasket, you have a leak in the transmission oil cooler which is inside the radiator. The cheapest way to fix it is to buy a external transmission oil cooler and hook that up to the transmission oil cooler lines which are now going to your radiator. then cap off the two ports on the radiator where the old cooler lines went. Your car will never know the difference, and your transmission will probably last longer as the external transmission oil cooler is vastly supirior to the one inside the radiator.
Check your radiator for signs of transmission fluid ( you will know as soon as you open the radiator cap) oily, creamy, gunky buildup. The transmission cooler is built into the radiator core and it is common for this to leak allowing coolant into the transmission and transmission fluid into the cooling system.
Look in the yellow pages under "Transmission Parts". Go to them and buy the proper cooler. They will show you the proper way to install the cooler. Do NOT use an auto parts store. (The top line is from the trans. to the rad., the bottom line is the return. Fluid flows downward in the radiator.)
If your vehicle has an engine oil cooler ther will be two hydraulic lines going to each side of your radiator. If there are only lines going to one side of your radiator, then it doesn't have an engine oil cooler.
remove the metal plate that covers the radiator, if you ever change a headlight blub, you already know which plate im speaking of... afterwards after disconnecting hoses transmission a/c lines just pull upwards, oh and disconnect plug to cooling fans it all comes out together ( fans, radiator, transmission cooler)
If it is a pink color then the Transmission cooler is bad in the radiator, If it is oil for sure then the engine oil cooler that's in the radiator may be leaking oil into the radiator. It would really help to know the year ,engine size and what you are working on. The above info may not pertain to your vehicle. Need to ask your question again with all information. THANK YOU NEUTZ.
if it has lines going from your oil filter adapter to a cooler in front of your radiator
Really need to know the year and engine size. But you can check this, Does your engine have 2 lines just above the oil filter that run up the side of the engine and goes into the radiator on the drivers side ? If so then that is the engine oil cooler lines and the tubes in the radiator were the oil flows through to cool the oil are probley leaking into the radiator coolant. IT happens often. WILL NEED TO REPLACE RADIATOR. And flush out the cooling system real GOOD. Did your engine freeze from lack of antifreeze ? If the radiator fluid is cheery red looking then the transmission cooler that is built into the radiator is leaking. REPLACE RADIATOR. GOOD LUCK.
Need to know the year, make, model and engine info.
Did mine last week. Firstly, undo the two wiring harnesses for the two cooling fans and then undo the two top bolts at the top that hold the plastic fan cowling to the radiator. Undo all the hoses that are attached to the top of the radiator. Lift the cowling (with fans attached) out making sure not to damage the fragile radiator fins when removing or installing. Now the trickier bit. The transmission cooler which is in front and to the bottom of the radiator and bolted to the radiator with two screws on either side need to be removed next. For some reason nobody will ever know (if you know tell me to put me out of my misery) one of the two small rubber hose that come from transmission cooler goes into a separate chamber in the bottom of the radiator. Another small hose takes it back to the engine. These two hoses need to be cleaned, removed and immediately plugged so you do not lose all your tranny fluid. Expect the tranny fluid in the radiator to come out on the floor, so cover it. As soon as you start the engine all air in the transmission lines as well as the bottom of the new radiator will be gone so you don't have to do anything further. Just a couple of things...... Don't bend 8 year old radiator hoses any more than you absolutely have to. Don't forget to top up the transmission fluid as per the directions with a Dextron 3 type fluid.. Be as absolutely clean as you can with the transmission hoses and the plugs you use to plug them.
The oil cooler isw up front in a suburban. Get a drain pan and a shop rag. Get under the vehicle with the line wrench to take the line from the cooler off at the radiator. Unbolt the cooler from the frame and take off the line from the transmission. If you are replacing the hose only or repairing it, just remove the hose and replace. Oh! and be sure to replace any fluid loss in the tranny with the correct fluid which any parts store would know.
Nope, a dealer said my radiator was "gone", and that transmission fluid may have mixed with the coolant, and they have to flush the tranny (180 dollars worth of tranny fluid) to ensure it is ok, add a new radiator, coolant, and a transmission filter, plus labor and you get 1100 worth of work-is this accurate? Yikes... yes a tranny flush is expensive (@ between $150 and $200). Plus, a new radiator. So, I'm afraid it's possible. But, they're killing you with labor costs. Just make sure that your car can handle a flush. In some cases, mostly in older vehicles, a true flush on the transmission can cause it to lock up, rendering it useless. I'm just taking a guess here, as I don't know what your driving, so I can't even guess how much a new radiator is for your car.
