WTEC III ELECTRONIC CONTROLS TROUBLESHOOTING MANUAL GENERAL DESCRIPTION TransID level 3 transmissions were produced beginning April 3, 2000 (see Table 1–5). A TransID 3 transmission is compatible with only V8A and later ECUs. Software V9 or V9A is required to use RELS. The following table shows TID3 S/N break points. The following table shows compatibility information between transmission and vehicle configuration. The following tables show further TID compatibility relationships when replacing an older transmission with a TID3 unit and when rebuilding an older unit with Dynax clutch plates. 1–16 Copyright © 2001 General Motors Corp.
