Can I bypass a leaking factory transmission cooler with a universal cooler?
When a factory transmission cooler built into the condenser starts leaking, you can bypass it by installing an external universal transmission oil cooler to avoid replacing the entire AC unit. This allows you to restore cooling functionality without messing with the air conditioning system, provided you choose the right size for your vehicle.
