Getting a P0700 code - New Builder Bill converter

Just got the Builder Bill converter installed about 100 miles ago. It is a 2800 stall. When I get on the throttle and then back off, I get a p0700 code. As soon as the engine light comes on and I get then "chime" sound, the car goes into what I think is limp mode. Meaning you can give it throttle and get the RPM's to climb, but the car goes nowhere. If you shift to neutral and slow the car down to almost a stop, you can re-engage the tranny by putting it in drive and your good to go again.

Any suggestions?

P.S. I just read some information of the Predator and there is a TCM adaptive "reset". FYI, I didn't do this reset, just put the converter in and that was it. Should I have done that?

Also, I have the old GSM traction control switch and I use that rather than turn it off on the Predator, dont know if it matters but thought I would add that in.
