I had a similar problem and ended up replacing both the lines and the radiator.
The transmission cooler (possibly part of the radiator) has failed.
if you have an automatic transmission there should be cooling lines going to the radiator to cool the transmission fluid the lines could be leaking or the tank could be leaking
check your radiator hoses and change gaskets
You have a leaking transmission cooler, usually part of the radiator. The transmission fluid is mixing with the antifreeze turning it pink.
If it is red or brown it is the transmission cooler (in the radiator) leaking. If it is milky white, internal engine oil leaking in to the cooling system, head gaskets.
The transmission cooler is built into the radiator, and the tubes on the cooler are leaking Trans. fluid into the engine coolant. Need to replace radiator.
Antifreeze is typically green, but the newer stuff is "gold". If you're getting red liquid leaking from the radiator it's probably the transmission coolant line.
Coolant? Bad radiator Radiator has a separate cooling tank (usually at the side or bottom of radiator) for transmission fluid. At times this tank ruptures allowing coolant to get into transmission. Most times causing a transmission failure.
It could be caused by a defective pressure cap on the radiator cooling system.
Antifreeze is green in color and is leaking from your radiator .
Leaking radiator? Leaking or loose radiator hose?
If the torque converter seal has failed you will need to pull either the transmission or the engine. If it's a half-shaft seal you won't need to pull the engine, just the axle shaft. I am the original poster, it is now leaking tranmission fluid & antifreeze at the same time. If it is leaking at the transmission cooling line in the radiator do I need a new radiator or can hoses be replaced or nuts tightened?
