MODERN FORD TRANSMISSION CALIBRATION/CONFIGURATION

摘要

The days of installing a remanu-factured, or a used transmission, in a vehicle and sending it down the road are now a thing of the past. This concept is not new. Since the 1990s we have had to reset Clutch Volume Indexes (CVI) on Chrysler vehicles. Resetting Transmission Adaptive Pressures (TAP) has also been an integral part of transmission repairs on General Motors vehicles. Modern transmissions may require more than just resetting learned values. Many of today's vehicles have Transmission Control Modules (TCMs) that are part of the valve body and require programming. Other vehicles need configuration procedures that require a capable scan tool. Some vehicles require registration of valve body and shift solenoid IDs to ensure proper shifting operation. Jatco CVTs, for example, that are installed in some vehicles, may even require programming of the PCM and the TCM, followed by a specific sequence of key cycles that allow the programming to complete and the chip in the CVT to "shake hands" with the other modules. Regardless of the situation, consulting service information before performing a repair is critical for a shop to determine if they have the tooling and knowledge to complete the job correctly. The key is to do the research, determine if the correct tooling is available and then quote the customer.
