The transmission was installed back into the truck and two electrical modules were interfaced with the PCM. One is called a voltage regulator designed to trick the PCM into thinking that it's seeing factory pressures, while in actuality it is allowing the transmission the benefits of the higher pressure DTT valvebody. The other electrical module is the DTT noise filter. It filters electrical noise, which can cause symptoms such as the transmission shifting in and out of gear, or the torque converter locking and unlocking.
