Auto Tranny?
What automatic was used in the 99 to 03 7.3 trucks?
Did they have the same problems the early E4OD's had?
How many miles would be a reasonable expectation before they need rebuilt?

I made it to a bit over 200,000 miles on the factory trans before it stopped working right. I have seen them last 60,000 and over 300,000. A lot has to do with maintenance and making sure they don't overheat.

I've been running 100 extra HP into my 2002 for the last 3 years, and over 200 extra for the last 3 months... It's holding together fine. For now 
EDIT: about 101k on it so far. TransGo Tugger, syn fluid, and 6.0L cooler as well.

My 4R100 lasted about 154,000 before the TC crapped and took the rest of the trans with it. Amazingly, the 2001 mechanical "diode" wasn't the problem and still seemed to be in working order. It is no longer in the transmission.

Thanks for the replies.
I have been looking at trucks in that year range with mileage usually between 100K and as high as 250K.
I would really prefer a manual crew cab, but out of 100 trucks within 200 miles, only one manual in the bunch.
All nice trucks, many duallies, most of them Lariets, but automatic tranny.
I must be a dinosaur with still liking to shift gears from what I am finding.

You and I both like to drive rare trucks I guess. If I could find one, the perfect truck would have the 7.3, a 6 speed manual and manual 4x4, but I guess convenience always wins with the avg consumer. I had a 7.3 IDI and finding a manual was much easier. I couldn't find a manual Crew cab long bed 4x4 anywhere so I decided an auto I could live with. I will be changing the auto out in the next couple of years for a manual. Quite a bit of work, but definately doable... Good luck in your search!

Yes that was one other thing I don't think I like, that little twist **** on the dash to engauge 4x4.
Is that a reliable system?
Glad you mentioned the 4x4, I forgot about that one.
I also like the lever on the floor with manual lockout's on the hubs.
Starting to think I just need to do some body work on my 86 and be happy.
Manual everything, I am spoiled.
I just keep looking at all that nice power that can be had, then I also think about all the extra headaches.

You can convert to manual hubs, but I think the **** is still required to switch the xfer case electronically. Somebody check me -- I drive a 2wd. LOL
But on the subject of manual vs. auto, my 84 'stang was manual (kept breaking the damn thing, so I put a C6 in it), my Bronco was an auto with OD (lost OD before I traded it off), then my Ranger was a 5-speed manual. That one I had to pull to fix a leaky slave cylinder (concentric combo slave cylinder/throw-out bearing). All in all, I think I've had about the same luck with either flavor.
That said, the autos are faster in these trucks once tweaked & tuned. And if it goes, you spend $4100 at BTS and you never have to worry about it again.

Sift through all of the Transmission's Broke, Help!!!!!!! or BTS or John Woods Transmission?????? threads in here. LOL.
I stumbled upon my '00 F350 CC LB 6-speed manual 4x4 PSD. I'm glad I went with the manual transmission. Lots of folks have horror stories about their automatic transmissions when pulling in the mountains here. No thanks.
I haven't had any issues with the vacuum activated 4WD. My '86 supercab 4x4 diesel is FAR superior in the snow than my '00 CC LB. I am actually surprised about this. Perhaps it's due to the lack of the limiturd slip in the '86.

The electronic shift system can be converted to a manual shift if desired, just as the trans can be converted. The one issue is time, and money. The factory hub system leaves a lot to be desired as the vacuum seals take a dump. They have a manual lock that can be engaged. I have warn hubs right now and only have to worry about the electric shift motor going out. I can't remember where I saw it but someone took the electric shift motor out and added a linkage making it a manual shift. The '92 IDI I had was a good worker, but even with the fuel turned up it wasn't up to snuff in my opinion. I am pretty happy power wise with my '02 7.3, and stock it is way ahead of the IDI I had which empty could do 65mph empty on a 8% grade, loaded, was 45 with the 5spd. If I had the choice, I would take the newer truck based on how my '92 worked, plus parts are a lot easier to come by. I found injection lines and clamps were getting hard to find on the IDI...

Well I am running one of those 25 PSI turbo 6.9's with milled pistons, DPS Stage 1 injectors and a day into night IP and all that extra stuff, so I am not lacking for power.
However, parts are getting hard to find, although what I really need worst is body work and more interior room.
I can handle the body work, but making the cab bigger is going to be a bit harder.
Looking on line I actually found a couple 6 speeds with manual floor shift transfer cases, but they are not very close to me, and of course are in opposite directions.
But then nothing seems to be easy anymore.
