Dakota 4WD V8-4.7L (2009)
Use the following steps to have the TCM learn the Alt 2C CVI.
1. Accelerate the vehicle through 88 km/h (55 mph) at a steady 10-15 degree throttle opening and perform multiple 4-5 upshifts.
2. Repeat 1 until the 4-5 shift become smooth and the Alt 2C CVI become stable. There is a separate 2C volume used and learned for 4-5 shifts,
2CA. It is independent of the 2C CVI learned on 3-2 kickdowns.
PCM/ECM Reprogramming

PCM / TCM FLASH REPROGRAMING
This procedure will need to be done when one or more of the following situations are true:
1. A vehicle's Powertrain control module (PCM) has been replaced.
2. A diagnostic trouble code (DTC) is set "P1602 - PCM Not Programmed."
3. An updated calibration or software release is available for either the PCM or TCM ECUs.
This procedure assumes that the StarSCAN(R) and StarMOBILE(R) devices are configured to your dealership's network with either a wired or wireless
connection. The StarSCAN(R) and StarMOBILE(R) must also be running at the latest operating system and software release level. For more help on
how to network your StarSCAN(R) or StarMOBILE(R) reference the StarSCAN(R) / StarMOBILE(R) Quick Start Networking Guide available on
'DealerCONNECT > Service > StarSCAN(R) and StarMOBILE(R) Tools > Online Documentation', under the Download Center.
