The ZF 5 speed is rated at about 450 lb/ft of input torque. If you're planning on turning up your Cummins too much, you'll definitely want to rebuild the trans. I ended up switching to an NV 4500 and an NP NV241 DHD. I'm at 758 lb/ft of torque on a chassis dyno, and my ZF started making some scary noises. BTW the little bag of parts adapts your ford sensors (Temp and oil pressure) to your Cummins engine. The T is for the vacuum.
this should definetly come with instructions im thinkin about doin this to a 79 f350
