This is exactly correct. The 700R4 is at best is marginal behind a 6.2L diesel. Yes it can work and even be reliable but the transmission needs to be set up correctly and the driver behind the wheel needs to know what they're doing (such as keeping it out of overdrive when towing and watching the temperatures).
