Calibration data transfer systems are described for use in conjunction with, for example, automotive components such as but not limited to transmission systems. The systems employ devices, such as but not limited to barcode systems such as 2D barcodes, radio frequency identification devices (RFID), digital data storage systems such as CD-ROM's, and the like, to record and/or store data thereon. The data can include information, such as but not limited to solenoid calibration curve coefficients and the like. The data contained on these devices can be accessed by a data retrieval system, such as a scanner, and transferred, for example, to a transmission control unit.
