Wondering what you have checked so far ? Have you used the Google and found the AW-4 Diagnostics and Service Manual that is floating around ?
Any blown fuses ? Any chafed wire insulation, damaged or broken wires ? Tested the solenoids ? The Dexron-III/Mercon is clean and fresh ? Tested the TPS ? Visually inspected the shift mechanism, Throttle Valve cable and Neutral Safety Switch ?. Checked the TV cable adjustment ? Checked that the Transmission Control Module has no corroded, bent or pushed back wire pins ?
