Tranny swapping
I'm starting to have problems again in my 99 350 auto. Instead of dropping a few grand more into another auto, I was contemplating having a manual put in. Don't know if it is even reasonable or practical. I don't see how it could be any more coplicated than the under-the-dash clutch set up. Then again, I don't know what I'm talking about.
Any opinions or advice? I love everything about the truck, can't afford payments of a new one, so I want to keep it.

IMO it will be the best thing that you could do for your truck. It won't be cheap or that easy, but it's do-able.
I think that you'll have to recode the ECU from auto trans to manual trans as well or it will get confused, causing drivability concerns and SES lights.
Let's see......
You'll need a flywheel, pilot bearing, and clutch
Transmission. (of course)
Clutch pedal assembly
Master and slave cylinder.
Is the hole already cut in the floor for the stickshift even if it's an automatic?
How about the hole in the firewall for the clutch master cylinder?

Kwik, maybe a better question for you, what should I expect to pay (installed) for a high quality auto? To make a long story short, I got taken to the cleaners a year ago and paid too much for a normal Aamco tranny rebuild. My alleged friend told me that he was putting in a very high quality tranny, certainly charged me for it. I have had all sorts of problems with it since.
What would you put in this truck if you planned on keeping it indefinately? I don't know anything about nor brands to look for. I'd appreciate any advice. Thank you.

I work on VW's for a living and don't plan on branching out, so I can't really answer your price question.
If the rest of the truck is still in excellent shape then it's worth the conversion. My guess is that you would pay at least twice as much buying a stick shift in comparable condition.
I suggest that you give one of the good transmission guys a call and see what they have to say. BriansTruckStop is the first one to come to my mind. Lot's of people swear by (not at) his automatics. He converts a lot of stickshifts to autos, so I would be willing to bet that he has plenty of spare parts laying around for the reverse procedure. I believe that he lives and works in Arkansas.

Okay, I have a little something to add. About a week ago, I was showing my brother -in-law my Predator and he said lets load the 85hp tune and see what happens. When it asked me Automatic or Manual I selected manual, because i must have been dreaming(or a few to many beers). The truck started fine but made a loud bark when it first started. I did not think anything of it until I tried to put it in gear and boom, truck shut right off. Tried it again, same thing. We came to the conclusion that since I selected manual instead of auto it did not tell the torque converter to unlock and therefore stalled the engine. My point to all this is that I bet you could use the same computer but select manual(if you have a tuner) or simply have it re-flashed to work.

On the subject of tranny swap can you simply bolt a 4R100 in place of a E40D or is it more complicated.

Yeah i was wondering that to, Hes my delema, i have a 1991 ford F-250 460 bigblock, and a 2001 ford F-250 PSD, The 1991 is a great truck but the tranny blew for its second time before i went down to the states from Alaska, so i enden up buying the 01 which is a great truck and i love it, I plan and doing some mods to my 01 PSD so im going to be putting out an order soon for a built ATS 4r100 tranny to pop in to my PSD, but i was wodering if the 4r100 would bolt into place of the E4OD in my 91. I know in the 91's day the diesels and big blocks from ford had the same bellhousing, the one on my 01 looks simular, i just dont know about the eletronics, well if you could help me out it would be great. I dought it can be done cause if it was im sure we all would off herad about it. THE E4OD IS A JUNK TRANNY.

A manual trany in place of an automatic. Oh what an idea. In the old days it was a very simple exchange, now days I can't even imagine the cost and possible problems to overcome. What about vin numbers and future smog requirements that might come into place. I live in SoCal and these are things we here have to worry about. There are many bullet proof automatics also to choose from and the cost could even be much less. 4R100 vs the E4OD, well it is my understanding that they are basically the same trans witch both have weaknesses. Either one can be built much stonger.

True the 4R100 is an updated improved E40D.
My thoughts are if your gonna have your tranny moded by say BTS wouldn't you be better off starting with the better tranny.
Besides as time goes by it's getting easier to find 4R100s in junk yards.

Phydeaux88. you can be assured that there are many trans upgrades to be had from many. The biggest problem with the 4R100 is the torque converter and the reverse drum. If one is using the original case it would be important to upgrade clutch packs and get a cast reverse drum (not the pressed steel one it has already) and of course a much better converter. All of these are availabe for all the OD automatics.

I have worked out most of the drive train bits for the swap but am looking for info on the ecu and what I will have to do to it. The other thing is with the harness what mods will I have to do to it. If any one has info it would be very helpful. Thank's

The electronics and valve bodies are also different from the E4OD and the 4R100. The two trannys are not interchangeable between the earlier and later vehicles. PCMs are not the same. My tranny upgrade is in the near future. I have an incredible trans shop near my location and will be making an appointment soon. Probably cost between 2 and 3 grand, but will be worth it

SIGH I guess the change would not be a simple swap out. Oh well ya cant blame a guy for hoping.
I know that changing to the 4R100 is what enabled Ford to upgrade injectors thereby producing more power. Of course more power required the Intercooler and wastegated turbo. I suspect the reason it all had to wait for the NBS is room under the hood. As we all know, there is a significant lack of room on OBS trucks
