help with 4R100 Differences

The trans has gone south in my 04 F250 5.4 4X4 and I've been searching but I can't find the differences between the years.

according to Hollander parts interchange, I can use 01-04 F250-F350 and 04-05 Excursion with a 5.4, but what are the differences with the 6.8 and 6.0?

I know they have the same bolt pattern but what would have to be changed to make them work with a 5.4?

From what I have found is the gas motors have a 7 bolt bell housing and the diesel has a 6 bolt pattern. The torque converters for the gas have 4 bolts and the diesel has 6 bolts.

The 6.0L, 5.4L, and 6.8L all have the same bolt pattern. Any transmission that will bolt to one will bolt to either of the other two, also. Having said that, you need to know that there never was a 4R100 mated to a 6.0L from the factory. The 7.3L diesel has a totally different bolt pattern and will not work.

A 6.8L trans will work. It might shift a bit firm because some of the clutches have more plates than a 5.4L trans. I don't remember which ones, that was a long time ago.

Thats what I thought, but wanted to make sure. This truck is the only vehicle I own that is essentially unmodified and I would like to keep it that way if possible. One example is my 94 Bird is a span from 1994-2003 and I have to keep a binder with part numbers so that I remember what I did.

I've got a quick question. What is the difference between the 4R100 and the 5R100 and are they interchangeable?

The first difference is that there is no 5R100.

The 4R100 is a four speed automatic. The 5R110W is a five speed automatic that replaced the 4R100. They are not interchangeable.

Anybody know what changed for 99, 00 and 01-04

The interchange only shows 1 year for 99 and one year for 00.

the Ford part number for 99 is XC3P7000CA
the Ford part number for 00 is YC3P7000BA
and the part number for 01-04 SD, 04-05 Excursion is 1C3P7000BC

I need a trans for my 04 and I found one from a 00.

Not sure but it may be programming or updated parts that may have been **** to breaking on 99 & 00 trucks. I dont know alot about transmissions but someone should chime in soon.

I don't know the specifics on every change. I believe all 99-04 4R100s are interchangeable, as long as they are correct with respect to 4x4 or not and engine size.
