This doesn't answer your question totally (trans weight?) but is still interesting.

6.7L Power Stroke Emissions System Overview
• Exhaust gas recirculation (EGR). A unique feature of the 6.7L Power Stroke is that EGR flow is controlled by the EGR valve prior to entering the EGR cooler, as opposed to cooling the exhaust gases before EGR flow is managed. This post-cooling system reduces sludge and soot buildup in the EGR valve, minimizing maintenance.
• Diesel oxidation catalyst (DOC). The DOC is a ceramic catalytic converter designed to oxidize hydrocarbons in the exhaust stream.
• Selective catalyst reduction (SCR). The SCR is where diesel exhaust fluid (DEF; 32.5% urea) is injected & mixed into the exhaust stream. Diesel exhaust fluid is used to convert nitrous oxides into water & nitrogen. DEF fluid level must be maintained to ensure proper operation of the system and the truck (an empty DEF tank will result in reduced performance and speed).
• Diesel particulate filter (DPF). A DPF captures diesel particulate matter (soot) and uses active regeneration technology to heat the exhaust system periodically, completely burning soot build up & cleaning the filter.
Additional 6.7L Power Stroke Info
• The 6.7L Power Stroke engine blocks are manufactured by American foundry company, Tupy. The engines are assembled in Chihuahua, Mexico.
• Ford Motor Company announced new power ratings for the 6.7L Power Stroke on August 3rd, 2010. Owners of the 390 hp model were able to receive a free dealer installed upgrade to acheive the new 400 hp power rating.
• The pre-production 6.7L Power Stroke was nicknamed the "Scorpion" due to its unique turbocharger mounting location and exhaust/intake arrangement.
• The 6.7L Power Stroke features an extremely flat torque curve; 700+ lb-ft is maintained from 1,600 RPM to 2,800 RPM.
• Single Sequential turbocharger features a variable geometry turbine housing.
• Reversed intake & exhaust flow. Intake valves located on the outside of the cylinder head, while exhaust exits into the engine valley where the turbocharger is mounted. Increases thermal efficiency of the turbocharger.
• "Instant Start" glow plugs which are said to provide quicker starts in even the coldest of weather.
• Compacted graphite iron block for reduced weight (160 lbs lighter than the 6.4L Power Stroke).
• Engine uses fractured cap Mahle connecting rods.
• Features piston cooling jets for lower piston temperatures. Oil is jetted into the bottom or the piston and travels through a cavity within the piston, cooling the top of the piston before exiting. This helps lower combustion temperatures and increase the longevity of the engine.
• B20 biodiesel compatible.
• 6.7L Power Stroke receives 18% increase in fuel mileage over 6.4L.
