Attention: TDR Forum Junkies 
autos have more potential!!!
I am am avid Ford Mustang fan, though I am still ticked over the pickup truck front ends that are "retro". I have read many hundreds of articles about which is better, stick or auto. I agree with the 30 year transmission mechanic about the number of pinions distributing torque. As a mechanical engineering major, I appreciate his analysis. The weak link is the clutch packs and torque converters in most autos. In the mustang world, it has been known for years that a C-6 auto, stock can handle upwards of 1,000 horses. C-4 auto can handle about 700 horses if it is built up. These are both aluminum case autos with no lock-up of course. The mad power cars in pro 5. 0 drag class often make upwards of 2,000 horses and I suppose by now all are over 1300 horsepower. They often use 2 speed powergilde auto trannys which were originally iron cased. The consistent message over the years has been for drag-racing consistent e. t. 's, go with an auto. On a diesel truck, the auto keeps the turbo spooled up and the engine making power where a stick would have dropped off and lagged while shifting. Under drag duty abuse, the sticks often desttroy the clutch or strip/break input shafts. Of course you can always buy a Lenco super expensive dog-ring stick which is basically a drag only crash box that is next to useless on the street. BAsically, if the autos were purpose built in Dodges to match up with the Cummins massive torque production at low revs, they would be highly preferred and more reliable than the 6-speed stick. Unfortunately, to keep production costs low, profits high, and us TDR guys with autos in the shop, they pulled a gas engine transmission out of the parts bins, programmed some wimp-out shift and converter algorithms coupled with the "torque management" wire-throttle garbage, and they have a auto that will drive off the lot and hah hah they got your money. I scratch my head as to why they don't offer a higher cost OPTION of a heavy duty auto like an allison or ATS sourced stage 5 48RE. Ford was willling to source its mustang sticks from Tremec, so there is a precedent for this. But, again, a lightly built slush box makes us come back for more PARTS!!! And, at $40 for a mopar/fleetguard fuel filter, they must be making lotsa cash!! I bought the 100k mile warranty for my 48 RE and at 19k miles it's doing fine, though no towing since I've had it. I'm not knocking the pv 5600, it seems like a great transmission, but for maximum power handling, I would look at a built auto. I might remind us, Greyhound buses have used autos for many years as have the huge land-yacht RVs. If the pro-5. 0 racers reach for an auto at 2,000 horses, maybe we should at DHRA levels.
