PDF-IMP Download: IMP Testing Electronic Transmissions - Import Vehicles

Developed by the Automatic Transmission Rebuilders Association (ATRA), this technical manual provides general diagnostic procedures for computer-controlled import transmissions. It outlines a logical diagnostic path—checking codes, analyzing electrical signals, and forcing shifts—to determine if a problem is internal to the transmission or within the external computer system.

The book includes specialized sections for Asian, European, and domestic import vehicles. It offers detailed guidance on retrieving diagnostic trouble codes, building a custom signal monitor, and identifying terminal pinouts and solenoid patterns for precise troubleshooting.
