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
