Attention: TDR Forum Junkies 
Wrong again. The transmission IS plenty strong for the typical driver. If you had any experience with them, you'd know this. But you don't. 
I tore it up doing a brake stand for a few seconds too long pushing 1100 lb-ft through the trans while locked in 4wd. Complete stupidity on my part, but I did indeed learn from my mistake.
When I rebuilt my trans, I replaced parts in the valve body, and more importantly I replaced the valve in the pressure regulator in the pump. The changes I made REQUIRED particular aftermarket programming. When that programming was overwritten by factory software, the transmission partially engaged the overdrive clutches and they burned up within a couple of weeks. This isn't the transmission's problem, it was my problem for not taking it out of service while waiting to get the software issue fixed.
You may be smarter than the engineers at Cummins and/or Bosch with regards to test procedures to determine if a lift pump is failing, but you're talking out your butt here. You simply have no knowledge of what we're discussing.
