When your vehicle is moving while engaging park the pawl will just slide out of the notch and slide onto the next notch. I also moved the shift lever to reverse while travelling forward at about 40km on an auto vehicle. I was trying to move from D3 to D4 but overshot. I heard wheels squealing and I quickly shifted it back to D3.
Didn't notice any damage neither. Not to suggest you to try this out. But park seems to be anohter story! Still even if you only damage the pawl and the rest of the transmission is good, the cost to repair it probably isn't going to be all that cheap. Do it once, by accident, hear the pawl click and put it back in gear--that's probably fine.
As your pawl tries to stop your output shafts from turning, it can endure significant damage, as can the gear that turns your shafts.
Once you do manage to come to a stop, your transmission will have suffered significant damage, to the point where there may even be metal shavings on the road behind you. With those consequences in mind, you may be wondering — is it even possible to put a car in park while driving at high speeds in the first place? Newer cars have a safety mechanism in place that holds the parking pawl still when a vehicle surpasses a particular speed. While braking at lower speeds can still damage your transmission, this safety mechanism is designed to protect the car — and you — from the worst of the potential consequences.
That said, older vehicles without this protective measure can shift from drive to park in no time at all. Can you put your car in reverse while driving, though? It seems like the option should be available — after all, drive and reverse are only a shift away from one another on an automatic gear shift.
Plus, you see pop culture icons like James Bond pull this maneuver off all the time. Unfortunately, pop culture and its affiliated conjecture could not be more wrong. The rotation of your output shafts is going to shift abruptly, and your parking pawl will attempt to come into contact with the affiliated gear to help with that transition.
That said, older cars respond to the drive-to-reverse shift a little — but not a lot — better. Years ago when I drove an automatic transmission car for the first time, I was o. A hot rodder in a souped up Ford coupe was gunning his engine. I decided to give him a run. We were abreast for a while then he started gaining on me.
Before you engage park, or at least before you release the main brake. Some cars make it difficult to engage the parking brake before you shift into park. The important thing is to not release the foot brake before the parking brake is set. I guess Mr. I was going along pretty well until the other car pulled ahead. I had the same disasterous results as before. I can vouch for that.
I once put my Bronco into park whilst traveling at 45 MPH the transmission was getting rebuilt the next day anyway , and I had supreme confidence that nothing would happen. Shockingly, nothing happened, the vehicle just continued driving.
I think that most if not all electronically controlled transmissions have that safety measure built in.
