After sliding into a snow bank, My 2006 Mazda 3 would not start. It wouldnt even crank. The next day when I went to retrieve it, It started right up. However, the automatic transmission will not go in gear. The shifter will slide into gear, even reverse, but the car doesn't move. It doesn't make any abnormal sounds or jerks. It just simply seems to be stuck in nuetral. Even reverse is nothing. Is there a wiring harness or something that may have been damaged? Please help me with this.

Check the shift cable that goes between the shifter and the transmission. If it's damaged internally it will not move properly and the condition you stated will be a symptom. Easiest way to check it is to disconnect the transmission end of cable and see if it moves freely. If not, replace it.

It's a fuse issue. Part of the shift interlock system.

If the radio is also not working, it's the cigarette lighter fuse. This one fuse controls the cigarette lighter, the radio, and the shift interlock system. It's in the kick panel fuse box on the driver's side.

If it's not that fuse, it's the "Stop" fuse in the same panel. Both blown fuses create the same behavior.

Easy fix! Don't bother with a mechanic. If the fuse continues to blow, take it to be checked.

Good luck.

Sounds like you flooded it not with water but with fuel due to moving car with out warming it up all the way before shutting it off. You can take it to the dealer and get a flash update to prevent this in the future. To deflood remove spark plugs and let sit with fan on them over night to dry out. Replace and start cranking for 15 seconds at a time till she starts up. GL!

Based on the information you have supplied, the car is not shifting in to the correct position. So when you try starting the car , it will not allow the starter to crank thinking it is not in park (which it is not...in reverse) I suspect that the shifter cable from lever to the transmission has become stretched over time and use. It can be adjusted at the transmission to shift cable hook up. The connection at the lever base could have also get disconnected. Try that first

look down on top of the transmission you should see a flat lever, just click it until u are in neutral
