Common signs of a failing transmission oil cooler include overheating transmission fluid, slipping gears, visible fluid leaks near the cooler, milky or contaminated transmission fluid (indicating coolant mixing), and erratic shifting behavior. On heavy equipment, you may also see warning indicator lights or codes. If you notice any of these symptoms, inspect the cooler and lines promptly to avoid costly transmission damage.
