Well I have had my 1st gen Cummins in my 91 Ford for about a year now and and sick of the auto transmission (I have always preferred manuals but worked with what I had). I have been looking for a NV4500 for awhile but they aren't easy to find around me and when I do they want an arm and leg for them. But I can find a ZF cheap enough that it makes up the difference for adapter plates. My question is how much abuse will they take? I plan to keep my truck in the 300 hp range but it will be used to pull trailers and will find its way in the mud pit and two tracks regularly. Will it hold up to that?
