Finished up the installation and drove it several times pulling my boat. Really satisfied with the results. Tinkered around with the controller settings to get a good shift feeling. And the Lockup converter settings based on MPH and TPS percentage. Mileage is much better what used to take a full tank is now down to about 3/4 tank for a vacation trip.

Pictures of the transmission with the TCI deep aluminum pan and the Mechanical Speedometer tail housing so I can use my original speedometer. Low stall torque converter for the 454.
