Does an external transmission cooler on a auto help the coolant temp to reduce as the radiator will have less stress to cool the transmission as well?

my car usually goes up to 105 celsius or 221 Fahrenheit usually after 3 or 4 runs but stays to 98 celsius on normal drive with A/C on ..new nismo thermostat new radiator and coolant 50/50 installed bleed the system 3 times.

will an external transmission cooler help??

The heat load from the trans won't affect your coolant temp.. If you're getting up to the 220°F range I would say you're probably ready for a new radiator.

hello,

i just had new rings and head gasket installed, new nismo thermostat , new KOYO oem radiator installed.

still it goes as high as 220F when im pushing the car on a drag strip, but it does come back down when i drive normally.

Are your cooling fans working? Do you have additional mods that you have done (nitrous, boost, etc)?
