Hello,

I have searched this part as used locally - to no avail. I need to buy a
new one.

Is this the right one, the same as used on RD-1C ?
http://www.ctpowertrain.com/servlet/the-239/C6-E4OD-4R100-NEW/Detail
I think this rear unit was 3.17, not 2.85 as in RD-1C (front?)

I know that this part code topic is discussed before - just that I moved
and don't have access to newsletter archives just now. Please bear with
me :)

Cheers,
Petri

That looks like the rear planet carrier.
That rear planet carrier will give you 3.17 for the same
direction in and out. Ring gear held stationary.

What I think you want is the front planet carrier. 2.85:1 same
rotation direction for in and out. Ring gear held stationary.

Petri, Search words "planet set"  on e-bay will bring up a some with free
shipping.  You want Ford F250/F350 super duty truck or any E4OD with six
pinions in the planetary. Make sure to get the sun gear and ring gear with
the planetary as a matched set. There is contact info for "performance parts"
available in the see other items link. I see them as low as $37.50 from this
vender. The front planetary is 2.85 to 1, rear is 3.17, transfer case is
2.72 to 1.   If you need the mainshaft or a hub just send a "note to seller"
or you could get the entire gear set and shafts also listed from the same
vendor. JEGS speed parts has listed the 6 pinion E4OD at about $126 new a
few months ago.
