If it has cooler lines they will run from the front of the transmission to the bottom of the radiator, but some of these models have an aluminum unit mounted on the top of the transmission that has heater hoses run to it instead.

replacing the radiator might help because if the cores are partially blocked the cooler cannot do the job
take it to an accredited transmission service center and have the bans and clutch packs adjusted
check that the transmission is not up past the full line as that will also over heat a transmission
it is advisable to consider the external cooler as it makes the transmission run probably 100 degrees cooler than a radiator cooler
for example with a radiator cooler the oil is at engine operating temperature ( 95-100 C) but with external cooler , the ambient temp rarely gets over 45 c so that is cooling the oil by 40 c even before the transmission starts to work
it also allows the radiator to be more efficient for the engine

well u didn't include any make or model into , so I cant possibly be exact in saying , but I can say transcooler lines run between the passenger side of transmission and the radiator (bottom) and that's also if equipped with an aux trans cooler as well (added hose to get there ) , there could be mounting blocks along the way that might be what your seeing ,sort of look like rectangular rubber blocks with clips or thru bolts thru them, these are just rubber blocks they don't do any thing other than hold the lines

It doesn't matter. But usually the left side of the cooler lines go with the left side of the radiator. Cooler lines run both ways, unless you deal with Dodge, stupid check valves. I take them out....

I'm wondering about the same thing on my '96 Roadmaster sedan. The lines use both coolers for transmission fluid. I have a wagon that uses one for engine oil & one for the trans. fluid. There's also a one wire (Thermistor ?) type sensor in a junction block in one of the lines coming out of the trans. Can't find a word about its function. I had to relocate it due to the cramped location. Area is so tight, that I had to wrap thread around the new fitting (About 25 turns) & then pull the thread like a Yo-Yo to thread it back in. Surprised the H.... out of me when it worked!

these lines could be coming from a transmission cooler, raise the hood on your vehicle, and look down in the front through the grille area, if it doe's have a transmission cooler, you will be able to see it, and then follow the lines that run from it to where you just described along the bottom of thre radiator.

It might be the transmission cooler line if you have one on this car, that leads to the radiator area.

The two trans cooler lines run from the trans to the radiator,they are routed along the engine block.
If you can find which one is leaking you can cut the line and install a piece of 5/16 rubber gas hose and two clams to repair it.
