These are HIGH pressure cooling lines; make sure you replace them with the SAME quality lines or they will rupture and leave you stranded. You often need a flare nut wrench set to remove them as they can be very tight. If they are just barely seeping I would not replace them ,but if in fact they are LEAKING then you need to update them.
The repair on the transmission line will depend on where it is. If the leak is at a coupling then the joint may be able to be tightened. If the line itself if leaking or split then it will have to be replaced.
"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
The transmission cooler (possibly part of the radiator) has failed.
The AT oil cooler is in the bottom tank of the radiator. If you are seeing oil leaking from one of the lines from and to the transmission connection could be loose.
You have a leaking transmission cooler, usually part of the radiator. The transmission fluid is mixing with the antifreeze turning it pink.
is coolant leaking from engine?or is it leaking from water pump and running down engine and appears to leak from engine
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.
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.
there is a transmission cooler inside your radiator and it must be leaking. probably replace the whole assembly
It's probably the rear main seals.
check your radiator hoses and change gaskets
