NOTE: Codo P0715 (15) on the PCM doesn't always moan there's an electricalproblem in the mainshaft or countershaft speed sensor circuit; code P07'15 (15)may also indicate a mechanical problem in the transmission. Any problem caus-ing irregular countershaft to mainshaft spoed difference can cause this codo; thiscan sometimes be seen in A'/T Free2e Data.
