Because there are lines running from the radiator to the tranny, this lets the fluid flow through and be cooled so that it does not over heat in the tranny and cause damage to your bands inside your tranny.
"transmission fluid leaking from fitting below radiator cap after replacing radiator on 99 surburban
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
You have a leaking transmission cooler, usually part of the radiator. The transmission fluid is mixing with the antifreeze turning it pink.
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.
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.
check your radiator hoses and change gaskets
I wondered the same thing. The radiator doesn't only cool the engine coolant, It also cools the transmission fluid that comes from your transmission through the cooling lines. So your radiator has a crack somewhere and that would explain the transmission fluid leaking out. Hope that answers it. William @ JeepGrandCherokeeTransmission.com
The better question is what is leaking transmission fluid?
If it is leaking trans fluid into the coolant it can cause overheating.
You have transmission fluid lines that go to the radiator/front for cooling you must have a leak there
there is a transmission cooler inside your radiator and it must be leaking. probably replace the whole assembly
