Is your check engine light on? If yes turn the key from off to on three times, on the fourth one leave it in the on position, the codes will display on the odometer, write em down and post em.

P1684= Battery disconnected during last 59 starts
P0700= Transmission control system malfunction
Could be a bad PCM ground and or bad neg battery cable, P0700 could be a bad TCM. Check the connectors at the tranny and the module, check fuse for the TCM.
