Nice setup you have going there, similar to mine.
What I did was lock the tranny into second gear, the BL motor has plenty of torque, and removed the oneway bearing. This way you can use your monster to run reverse and brake which is working great for me. The following link will show you what needs to be removed from the tranny and what needs locked, go to the bottom of the page,

Once this is done your reverse module, if you have one, comes out and so does you manual brake along with all supporting hardware, sure does clean things up.
Truck runs great with no issues at all. Oh ya, your FLM kit doesn't come with instructions so use this link for any help you may need,
