Questions for Chris Brewer - chief engineer for the 2011 Superduty
#121
Meaning you no disrespect, this is a gripe that many have with ford right now. Maybe with any luck if we do enough crying about it, we stick shift lovers may get the truck we desire. Doesnt seem like ford is listening anyway.

1. If i wanted to swap in a ZF6, are the bolt patterns the same?
2. if my brakes go out and im going down a hill, can i drop a gear or two and use my engine to help brake?
3. could i shut my engine off in a certain gear to slow down?

I don't know about Q #1 & #3, but #2 I know a little about.
The 6.7L PSD comes standard with an engine brake, and from what I hear its better than the one the 6.7L Cummins in the RAM trucks comes equipped with. I don't know what the dura-diapers come with because I don't consider those to actually be trucks. Will the engine brake bring you to a complete stop, highly unlikely, but it should slow you down enough to safely use the parking/emergency brake.

2. the same way you would with a manual transmission
3. the question could be interpreted two ways a). Does shutting the engine off increase engine braking - probably not since there is no intake butterfly on a diesel and therefore no intake braking, so there would be no increase in braking since the injectors can shut off completely when you lift the accelerator b.) does the exhaust braking system work when the ignition is shut off? Don't know but this is most likely an ECM controlled function so probably not and you would lose braking capacity by turning off the engine.
One of the previous posts suggests the capacity to use the "parking brake" to be able to slow the vehicle if the service brakes failed - this would likely be ineffective since in most vehicles with disc brakes the parking brake is a tiny accessory brake which would burn out immediately

2) From what I've read, the torque converter should remain locked in that situation, so theoretically the answer is yes down to the point the converter unlocks. The exhaust brake option should also help.
3) Shutting off the engine in a vehicle equipped with power steering, power brakes, a steering wheel lock and all those electronic controls while it is still moving is a very bad idea. Unless you drive a Toyota, I'd recommend leaving the key on.

Superduty manual transmission
Ok, if the ZF6 manual is only rated for 620 ft-lbs why not step up and use the 7 speed manual in the medium duty trucks for the F250-350 etc? I'm up for a new truck, but don't like the fact that from 2008 on up the interior of the truck is horrendous compared to my 2002, door panels suck for storage, steering wheel is a disaster, passenger seat has lost legroom from the tranny. The gas engine has NO ***** or responsiveness, and the worst part about the *** end of the truck is the tail lights with the reverse light on top. The thing that pisses me off most, I now have the chance to buy a diesel with a manual tranny and Ford decides to stop putting it in the truck. IS THIS GOING TO BE ABLE TO BE SPECIAL ORDERED since the bolt patterns havn't changed?
Ford is going to loose customers unless they can provide WHAT THE CUSTOMER WANTS AND NEEDS, or they just plain forgot what made them the best seller... MORE OPTIONS FOR DIFFERENT NEEDS.

1. what happens if the brake interlock fuse goes out and i cant shift out of park? (happened to an expedition, wouldnt happen with a manual)
2. is there any option to have a transmission with practically no electronics in it? or are we screwed with this 6R140 or whatever it is?

Dont know about fords, but in some other makes, if you have a dead battery, forget about putting the car in neutral

Most (if not all) have an emergency method. Worked on an Acura today that you had to insert a screwdriver into a hole to push the release. Haven't seen too many without one (been turning wrenches for over 35 years)

jeeze im sorry i brought up the manual tranny thing. maybe it will show ford that people that actually USE there truck as a truck, not as a show toy, want a manual.

I have a simple question for you here. For the 2011 models i was reading that the EPA requires fuel economy ratings on all vehicles upto 10k lb. Excluding trucks. Why doesnt ford actualy let the EPA rate the truck as we all know they will require it soon enough. A rating on the window sticker would definately help ford push gm and dodge to also get that rating and than if ford is truely the fuel economy leader it will more than help sales.
Thought of this after my post. Is there a reason why ford decided to build a new 6speed vs using the "dual clutch" setup on a newly designed 6speed. Comparing a torque convertor to a dual clutch setup there is some more power at the wheels and fuel economy to be gained.
