Default Trans code p0720 help, please.

Ive posted this in the Integra forum with no replys so Ill try here. I have a p0720 (output speed sensor) and I cant figure out why. I replaced the trans about 6 months ago and it works great. No hard shifts, all gears are great, the speedo works fine, and no codes until now. I have to pass emissions so I cant have any codes present. I have another integra with no codes so I have swapped the speed sensor and the ecu and after about 3 miles the cel comes back on, same code. I have also depinned the plug and it looks great. Any ideas? I dont want to be told I need a tranny cause this one works fine.
