Please don't crucify me or kick me off the forum but I need a little info and I'm not getting much love on the SD forum. Big surprise huh? So maybe some of yall have the answers or hopefully Chris will pop in with some knowledge too. Anyway, I know about most of the differences I think but here are some things I've not seen covered and I'm not finding in search or stickies. Here's the thread so far. No link. I'll just continue here if it's ok so as to not P anyone O.

I'll be after a cclb 250 or 350(most likely 350 but don't really care) 4x4. Intentions are daily driving with occasional light towing. Plans: airflow, gauges, tuning, injectors(160cc max with maybe 100% nozzles max but probably 30%), and other supporting mods
They only came factory with 3.73 or 4.10s correct? Is there a door code list somewhere so I can know when I'm at the truck?
Is the 4R100 any tougher than an E4OD or should a 6 speed be the only choice anyway? I doubt I'll ever be able to build an auto. At best MAYBE buy a racer x kit and have someone build it for me or a used BTS.
What kind of RPMs are yall turning with each trans/gear combo?
Are the single shots hands down better than splits? For power and mileage alike?
Sorry for the list but thanks in advance for the help.
At the top of the forum are stickies - one of them is common mods, acronyms, etc. but the one above will help you out.

Im running 1900 at 70.
Yes the 4R100 is stronger than the E4OD, except some of the 2001 models due to a mechanical diode thats prone to screw up. At the end of the day tho, 4R100 is just an upgraded E4OD.
From what I hear, singles are the way to go.

Thanks man. 1900 at 70 sounds pretty nice. I'm at 21-2200 at 70 with the ZF5. I know there's a door code. I was thinking maybe somebody has a list of the codes I can look at somewhere.
Are the forward gears in a 4R100 the same as an E4OD?
Here are the superduty axle codes, should be on the sticker in the door...

As for singles vs splits, yes singles are better. Many pick up fuel mileage switching to singles. The only issue is having to tune for them.
I wouldn't count out getting an auto, I would just be sure to pick the right one. The post above explains about the mechanical diode that gave a lot of people trouble. Either way, it's still an auto transmission and that's just that, when you start throwing money into injectors and what not, you might have to throw money into a transmission to get that power to the ground, that's just the name of the game. Same way with a manual, getting a clutch. Gotta pay to play...
I don't have any personal experience with the 4R100, but I know the Super Duty's are running 140cc or so split shot injectors from the factory, so the transmission should be able to handle stage ones without much trouble. I know I have read a few posts in other forums where people don't say it's much use to upgrade to stage ones because it is only a 20cc increase. However if there is the possibility of getting better mileage with single shots, then it very well may be worth the upgrade. I do know my buddy's 2000 F250 is much quieter in the cab than my 97 F350 is, not to mention the ride improvement. Not to say you didn't know already, but be weary of the 2002 and 2003 models with the powdered metal rods in the engine if you plan on playing the horsepower game at all.
I was thinking the factory sticks are 120cc splits but not positive. Either way, it has to be a significant upgrade with 20 - 40 cc more fuel and higher than stock nozzles. I dunno though. Maybe someone with that experience will chime in.
And as far as the rods, I don't think it is just 02 and 03s to watch for. Reason I say that is because I read this elsewhere:
Start of production thru 1425746 are Forged Rods
1425747 thru 1440712 are Powdered Rods
1446713 thru 1498318 are Forged Rods
1498319 thru final production run are all powdered
I'd like to think I'll be fine with PMR but there have been reported failures after only a chip so I'd like to avoid all together. I won't be chasing high numbers but don't want to feel limited either.

Only early 99's had AB - 120cc injectors. 99+ had AD - 140cc injectors...
PMR's were started in 2001 and you will be just fine with a PMR truck.

I see now. I guess we are both right

Yeah, I think if I find the right truck and it happens to have them I won't be able to turn it away on that alone.
And I haven't forgotten about your SD either. I really like it. If this OBS sells and I can get all the logistics and such worked out we may have to do some business.
there is nothing wrong with PMR's, or 4R100 transmissions.
i have a DP tuner on my 02 with a 4R100 trans. i beat the snot out of it, and it now has 174k miles on it.
only routine maintenance of both engine and trans.
5000 mile oil changes, and 30,000 mile trans fluid and filter changes.
I haven't had any personal experience with PMR's, just have read a few places where people had problems with them, I guess it's kind of hit an miss and how you drive the truck. Guess I learned something about 120cc injectors too...
The trans is a little tougher e40d with a coue extra sensors. The PMR is fine if your wanting a good reliable DD and tow rig but if your looking to build lots of power then it wont last that long

Let me know... I don't know how much longer it's going to be around though, have a fairly serious guy interested right now... I'll keep that thread on PSN updated so if it's still up there it hasn't been sold.
i agree with that!!
i am torn between the ride of the stupid duty and the looks of the OBS.
i love my 88, but with my different health issues it gets harder and harder every day to get in and out of the 88, and the stiff ride is killing me.
