Transmission Limits???

He guys, I was wondering if anyone knows the limits of the stock 4R100 transmission? Looking at the banks power pack system and want to make sure it can handle it as well as when towing ....

In my opinion, the stock 4R100 is barely able to handle the 7.3 engine as shipped from the factory.
On the flip side, when properly modified they appear to be very durable units.

The limit for a 4R100 is 1000 lb-ft of torque after the torque converter multiplies torque by about 1.9:1 at maximum multiplication. So 1000 / 1.9 = 526 lb-ft at the flywheel.
