Need help with a p0756 code

OK reaching out for some guidance. The other day I was driving back home from work and my 2006 6.0 diesel superduty 115,000 miles, started shifting really hard into 3rd gear. by the time I got home the tow/haul light was blinking. I did not get any other check gauges or other alerts just the blinking light. I went out and purchased a code reader and it came up with the p0756 code(shift solenoid B performance or stuck off). I then did some research and everything I saw suggested replacing the b solenoid. So I ordered the part from ford. After about 2 hours of work I replaced the solenoid, two transmission filters, and new fluid. I cleared the code and took it for a spin. with in a mile or two the tow/haul light flashed again. I pulled the code and now it is a p0757 code (P0757 - Shift Solenoid 'B' Performance or Stuck On). So my question is this a code that just needs the truck to be driven to let the computer recycle itself? Did I possibly change out the wrong solenoid( if looking at the diagram I replace the second solenoid from the left in the row of 4) Any thoughts. I never have had any problems with it prior to this. Thanks in advance for any of your suggestions. Brian
