I would personally run the radiator cooler and then add an auxiliary cooler into the circuit. It’ll not only help keep the trans cooler when hot but it will also help it get to operating temperature faster. Even though the radiator is 195 degrees the coolant is still very effective even in hot climates. Liquid cools better than air. OEM’s still use this setup because it’s effective.
I owned a 93 Exploder that I gave to my mom several years ago. The A4LD is notorious for early failure. Original trans now has 180k on it with nothing but two driveway flushes since I bought it with 125k on it. I’d opine the secret is the auxiliary cooler the original owner installed. The fluid goes through the radiator first and then the cooler. Shifts like new.
