Unless you REALLY need the overdrive, I wouldn't bother with the AOD in stock form. A lentech valvebody will re-route the fluids to allow a 1-2-D/OD shift pattern vs. the 1-D-OD (uses a solenoid and switch for OD). The inner input shaft responsible for the direct drive of 3rd and 4th is also a weak point. When shifting hard from a torque converter powered 2nd gear to a direct drive 3rd gear, you can snap the shaft. A lentech valvebody will hold 1st and reverse bands (which allows 3rd gear to be powered by the outer torque converter shaft) but your overdrive is still weak.
I chose a C4 because its smaller, lighter, and draws about 18-20 hp instead of the AOD's bloodsucking 55-60!
Will a C4 handle the horse power/torque of a 351C for daily driving and weekend drag racing?
How much hp does a C6 draw from the engine? I've heard that a C6 is more durabable but less efficient than a C4.
I am removing the AOD from my 351C Ranger and I am going to buy a C4 or a C6, not sure which yet. Open to suggestions. Anyone?
