If the forward gears, still work OK, you probably broke the first/reverse band, or strut. |

Sounds like it is time to drop the trans pan and have a look inside.It could be that a simple band adjustment will fix the problem or as Charrlie_S suggested, the rear band is broken and it will need to be replaced. One other possibility is that the rear band servo piston seals are worn / torn or leaking. These can be replaced without removing the trans. DD |

DD. I'm thinking, since he was rocking the car, between forward and reverse, the band broke. The other possibility is , if the rear band was loose, the strut might have popped out. If it is the strut, it might be possible to get it back in, with a lot of patience. Then readjust it correctly. But I agree, time to drop the pan and have a look. |

I vote for a broken reverse band. Back when I was young and stupid I wondered what would happen if I put my Valiant in reverse when I was going down the road forware at a slow speed. Well.... I just killed the engine that day. A few weeks later as I was backing up I hear a BANG !! and I had no more reverse. Yes it was a broken reverse band. Look for a dent in the bottom of the transmission pan.... from the inside out........ when the band broke, some lever inside was free to dent the pan from the inside. |

If you try driving downhill in 1st. Does the engine try to hold the car?(engine brake) or does it just roll like in neutral? Anyway I think you have to open it up and have a look. |

definitely pull the pan. Check for three things: Low/reverse band looseness or breakage Band apply strut damage or mis-location Sticking low/reverse servo assembly (you may need a C-clamp to check this, space permitting) |
