Driveline Integrity After Being Pushed Backward In Gear

[usury]

Hey Pokes,

My neighbor/landlord struck my parked car in my driveway. The front corner is smushed, obviously.

That damage aside, I'm concerned about what happens when a car parked with the transmission in first gear is hit hard enough to roll the car back about two feet. It left no indication of skidding those two feet, so I'm assuming it rolled those two feet.

What slips in the driveline by design/accident, or what intentionally fails in that situation? Non LSD transaxel, in case that matters.

I assume the trans in first gear might be able to spin the torque tube the wrong way when the car moves backward. Will the clutch slip if it is spun the wrong way? Can the engine be spun the wrong way if the clutch stayed engaged?

There is a gap in my knowledge between how all the parts go together and how they work together, especially in an outlier situation.

I haven't tried starting the car yet, preferring to get some insight about potential driveline damage first.

Yes, I have insurance. Yes, the other party does too.

I would not expect any drivetrain damage. The engine will rotate backward, as easily as it rotates forward. As long as the timing belt is tensioned properly, no damage will occur.

A very long time ago (circa late 70's), a friend's International Harvester was hit (hard) in the rear while parked in gear and it broke a gear in the transmission. That thing was a tank -- it suffered body damage in the back, but nothing that couldn't be fixed, while the car that hit it was totaled. I think the only way to rule out any problems is to start it up and drive around. Based on that dent, I'd be very surprised if it's any more than a dent... Sorry that happened though

I don't have anything productive to add. Just sending my condolences. Hate to see this! Sounds to me like you are owed some free rent for the troubles and emotional distress
