Default code 84 fault ?

happen the other day I was able to drive home but I had no 1st & 4th gear plus it would not lock the tc.. looks like it went into a limp mode
I put it on my scanner and it threw a code

Err84: 3-2 Downshift Feedback Fault

and my tc press was @ 90 all the time plus other wierd things
I rebuilt the tranny about 6000 miles ago.

I replace my ignition switch a few months ago so I don't think its that
but what you guys think?

could it be my solenoids?
would that threw into a limp mode
thanks guys
