E-Series VansTechnical discussion of topics related to vans powered by any of the Navistar engines. This covers a broad number of years, but there isn't enough demand to split it any further.
Hi all,
Anybody know what build # or year model Ford switched to the 4R100 transmission in the E350 diesel vans?
Which is the better trans?
Also I believe they switched to rear disks about this same time which im sure is a big improvement. Should I be looking at the later year 7.3l (1999.5+ I think) to get these features? Is it that big a deal?
Thanks
Aaron
They are the same transmission, the E4OD was renamed to conform to ISO standards. The differences that you will see between the "named" transmissions are because 4R100's are newer and so have the newest design parts.
As I have been on the hunt for a replacement van and research and receiving input, from a mechanicals standpoint it seems the 99.5 to 2000 is the best combination of mechanicals. Those years get the rear disks on the full floater rear,a 4R100 and you will get forged rods in the motor if Modding is your thing. The exact start of PMR (powdered Metal Rods) is the subject of much debate, but if you don't plan on building a High HP PSD (Over 350-400) its not an issue. PMRs started sometime in 2001 as did he semi float rear end.
You'll get the dead head fuel system which can give cackle and other injector noise in 99 and up, but that can be cured by the ITP regulated return system. The 98van I was looking at in MI with the old style non-dead head fuel system was Quiet, quieter than my '03.
The 99.5 and up get you the larger turbo intake pipes and some other upgrade for more base HP. Cheaper to add a reg return to a 99.5 and up, than to upgrade the turbo and intake on a 98 back which may also require injector upgrade (more turbo means you need more fuel).
Thats the short version of some of the information out there. I would buy the newest van withthe least amount of miles you can afford. My price point puts me out of the 99.5 and up unless I want a real high miler or an up north van.

1999.5 F250 CC SB XLT 4WD, 7.3 PSD, First F,2nd Diesel, nice but still liked the van better.
2003 E-350 Super Duty Chateau (Club Wagon)7.3PSD, 3rd Clubwagon,First diesel, Never should have sold it....

It's not a relative torque rating, it's an absolute torque rating. The 100 means 1000 lb-ft torque capacity after the torque converter. The torque converter multiplies engine torque about 2:1.
Hey ddog,
Thanks for the reply -
Regarding:

Ive read a bit about the cackle issue and im not liking it or the increased noise issue. How prevalent is this problem?. Shouod I be looking for pre 98 for these reasons?
How big a fix is the "ITP return" Cost? Hours?
Cheers

I thought the torque converter(TC) locked up was only transmitting all engine power 100% without slippage. I didn't know it had gears in it to multiply output?

E4OD and 4R100 are not the same. The 4R sprung from the E4. Lockup and pump are not the same and require different programing. 4R has pulsed lockup.

Minor differences, no more different than different years of production of the E4OD. The only parts of the transmission that is electronically controlled is the solenoid pack, which is a 10 minute swap once you have the pan off.
It's like comparing a 1969 302 to a 1989 5.0L. Not all the parts directly interchange, but it is the same motor.

OK, look at it this way. When you get a repair manual, on the cover it says "E4OD / 4R100". The cases are the same dimensions, the internals are the same dimensions, the oil pans are the same dimensions.
I understand that a 2002 4R100 won't bolt directly into a 1989. Nor will a 1996 E4OD bolt directly into a 1989. Parts need to be changed to match the computer programming of that particular truck.
If you want to get really technical about it, you can ID a 4R100 case by it having a PTO port, where a E4OD does not.

Correct
But all has to be from a 7.3. Bell housing bolt patterns are not the same for gas and diesel. Not even getting into that the diesel has more clutches.
Not to start an arguement, but the A4OD and 4R100 are not the same; specifically, the parts will not interchange. I can't give you all the specifics, but when I had to replace the torque convertor on my E-350, there was a different part number between the A4 and 4R. I'm getting ready to install a US Gear Underdrive and the connection parts are different. The best advice is to take everything that you read here with a grain of salt and talk with a Ford parts expert for your final decision.
