Above 45 mph, the transmission and engine matched seamlessly .

The transmission now works fine until around 14 miles when it warms up. Then the speedometer stops working as well as the odometer. The car won't shift into high gear and the mileage drops to mid twenties versus mid forties.

When using a grille block the transmission warms much faster .

Not sure if I just have s bad transmission or if there is a connection.
Sounds like a bad speed sensor if that model does not have a cable driven speedometer.
