Darryldickie I believe I have the same problem.
Did you have a shop do the work or by yourself?
If a shop where are they located? I'm in LA, CA.
I have a 2012 V10 E350 4X4 done by SMB.
Please clarify if possible. When SMB ads the 4X4 system, the stock transmission is modified by adding a adapted tail piece to match up to Atlas transfer? If I need a new transmission It is stock unit? Mine is slipping some times, but shifts fine but blew out a bunch of fluid not Shure from seal or vent, happened last weekend.
Thanks in advance for any info.
2012 EB 4X4
