SOLVED - '08 xl loss of power

[johns2008]

I'm having a serious loss of power,, 300, miles just replaced the fuse box . radio face is acting up. is there anything in the transmission it could be.. doesn't seem to shift down . like it's in mid range?

Put a good scanner on it and see what codes (history, pending, current) are showing up. Then list them here.

Since you just replaced the fuse box, start there by verifying it's exactly the same as the old one, everything plugged in, no corrosion, etc.

Also when did this problem start, and what's been done to correct it?

Yes to the fuse box in question.. I reset it in its cradle and everything works accordingly. thank you all.
