Upgrades:
As we all know, the CTD's can produce WAY more power than they were sold as. At some point something has to give.
Most of the time it's the Converter Clutch in our trucks. How does that work?
Well the guys with a handshaker

have instant "lock-up." Our trucks with the automatic have the best of both worlds. The fluid multiplication and the Locking abilty of a manual.
Like I said above, the converter works with the 2 fan principal. Obviously there is some "slippage" there. The fans will never turn at at 1:1 ratio. So, to make the transmission more efficient they add a clutch to the system. This now gives us the 1:1 ratio, just like a manual.
No big deal....right? Sorry....just like the guys with a manual transmission, when they start Bombing, the clutch starts to slip. We have the same issue. So what do they do? Add more clutch material for one. Another way is to use multiple clutches.
Manual clutches they can add more pressure plate, pressure. A stock automatic has....for simplicity sake, 100psi on that clutch. Now if you add more clutches, lets say a tripple disc converter, you've now more than doubled your holding power within the converter clutch.
Now no more slippage!
