Do these trucks have engine brakes on them? My 2001 f350 psd takes off while descending a hill, even if I shift down into 1, its an automatic. It acts like it is in neutral until I hit the accelerator. I dont understand this b/c my wifes honda accord I can put in 1 and slowly descend the mountain but my diesel I cannot. My brakes are smoking and almost on fire every morning I drive down the hill. This is during everday driving not even pulling a trailer. Someone please help!

You've got a few options (really just one, now that I type this out)
You can setup something (some chips have this, I'm sure) that will lockup the TC when you're decelerating.
You can use the EBPV (warm-up valve) to act as an exhaust brake. This won't really do you any good unless you do the step above. (In fact, it won't do anything)
The EBPV wiring diagram has instructions on how to set your TC to lockup.

I turned my EBPV into a brake and my opinion is that its well worth the $30 I spent doing it. The one thing I did notice is that after installing my 4" exhaust it doesnt hold back as good but with my 6 speed it was almost like dropping a gear. With the 4" it still hold back good though.

x2. The torque converter is unlockin when you're goin down the hill because of the speed and light load on the truck. I would put a TC lock-up controller on it, and I'd even do the mod to make your EBPV and exhaust brake. Oh and yes, exhaust brakes ARE DIFFERENT from engine brakes. Engine brakes are what are used in big rigs. It is actually a cam in the engine the lets the air out of the combustion chamber. That's why you get the barking sound. Exhasut brakes go on the down pipe of the turbo and are essentially a butterfly valve that opens and closes. When closed, it holds the exhaust of the motor back, thus slowin the truck by putting more back pressure on the motor. Exhaust brakes make more of a hissing sound, like your EBPV when it's closed when the motor is cold. Almost sunds like a loud vaccum leak. Both work well, but unfortunately, you can't get engine brakes for these (and most other) pick ups. either way, they are almost worthless with an automatic truck, because once the TC unlocks at low speeds, the engine goes to idle and is doing nothing. They are more worthwhile on a manual truck because you can let the clutch engaged as long as possible to gain the most engine braking possible. It does however, work well on autos with the TC lockup mod. Here's the how to link to make your EBPV and exhaust brake and I believe the TC lockup mod is on there also.
