My new transmission is (still) overheating on long highway drives.
Transmission shop tested the t-fluid flow rate through the radiator at
1 quart every 30 seconds. The transmission itself however will push times that amount, 3 quarts every 30 seconds, all by itself and also through an aux t-cooler.My radiator is only 2 years old. When I first started having transmission overheating I found the radiator was shot and had it replaced and later put in a tran cooler too.
So the questions is... What should be the t-fluid flow rate through the radiator? In other words... is my radiator restricting t-fluid flow rates below spec?
