Just out of curiosity, how much boost / power are you trying to get out of your 6.5TD ???

The NV-4500 is a great trans for strength, but wont be a speed shifting trans

Not telling you what to do or being rude, but if your are trying to get much over 350 HP, you are waisting your time & money
6.2 / 6.5TD engines are ok, but arent power houses (Ive owned a few & tried to build power with them, so Im speaking from experiance)

If you are trying to get good MPG, then hi horse power isnt needed & you should be ok

But I dont see a 5-speed getting you better mileage, especially if you drive in town / traffic much
Yet a over drive Auto would be better
