Im not sure what Torque Converter I have or what the stall is since I bought the vehicle the way it is. Im shifting nice and smooth and it seems to downshift if I step on it extremely well but it seems my RPM's are a little high for my setup. At 80MPH my RPM's are 3000 with 3.73 rear and 26.1" tires. Depending on the Calculator I use it varies but 3000 still seems a little high. The video is of the transmission shifting so if you can tell by the Tach please chime in.
