Im sending my computer to bb for a tune and was just curious is there only one computer on the 01 fro the motor and the trans? the 08 had 2. i took the one from under the hood already
My 04 only had one computer so I would assume yes. NNBS trucks have a PCM and TCM I believe, which is why most handhelds cannot turn off torque management on the NNBS's.
