P0715

NOTE: Code 0715 (15) on the TCM doesn't always mean there's an electrical problem in the mainshaft or countershaft speed sensor circuit; code 0715 (15) may also indicate a mechanical problem in the transmission. Check the freeze data with a Honda PGM Tester. If the mainshaft speed sensor rpm was 0, proceed with this troubleshooting. If not, the probable cause is a mechanical problem.
