What will happen if

[SupremeVT98]

A Commodore automatic travelling at 110 km/h and suddenly you put the gear in reverse accidentally?? :o

A horrible noise and a lot of damage? or the engine would stall ?.

I dunno never tried it and hopefully never will. :)

Nope. I'll wait for the correct guess or answer before I tell what happens. I'm not even sure if what happened is really what will happen. LOL

Seen it done. As long as you keep full throttle at the time it will just light the wheels up going backwards and chuck you sideways. Excellent drift technique for corner entry to set up the slide pre-apex if you dont have a manual (where you can pump the clutch) or a hydraulic handbrake. Referred to by the drift king Keiichi Tsuchiya as 'Shift Lock'.

Mate was hitch hikeing home one night from the pub and was picked up by a bussiness type dude in a newish BMW , the :limpy: leans behind the front seat and pulls out a mag with 2 guys on the cover, one chokers up the other,and asks if he has seen a mag like this before. Doing about 70 km me mate slams it into park.........big lock-up. Dont no if mr gay man will do that again..... :lol: F...king gays ( not that theres anything wrong with that) :rolleyes:

[VooDoo]

You sure you saw it tuna??

the 4L60-E has some failsafes built in and putting it into reverse wont actually do anything at all. It wont engage reverse over a certain speed. I would have thought you knew that.

[SupremeVT98]

OK. This is what happened to my VT Commodore.

I was doing 110 km/h along south dowling, Im on third gear all the way from 60-110 when i hit the expressway, I was gonna push harder on third but decided against it and put it in D without looking.

:( I nudged it a bit harder like I used to with manuals and it went to R-reverse.

I'm not sure if this is what will really happen if ever you do that accidentally but the engine shuts down...I lost steering, no brakes. The speed decreased dramatically and luckily I was quick to push the hazard lights coz this idiot's tailgating me.....

No damage to the car that I can hear or feel, maybe not yet anyways...

[HyperUTE]

It burns the forward friction in the transmission. How you know if this has happens is if when down shifting manually, it seems to slips abiit.

[Inter-ceptor]

I was shifting gears from neutral to D one day and at one stage I forgot that I had my gear in neutral as I thought it was in D, so i shifted it up and it went into R (about 80KM/h) I immidiately realised it it was in the wrong gear so I changed it back, nothing happened anyway...

Putting an auto trans into "park" while moving only makes a loud bussing noise beacause the teeth that lock the drivetrain can't lock in until the car has stopped.

As for reverse, I tried it a few months back in a VY exec hire car at 100kmh and it took maybe 2 or 3 long seconds and then "boom", one single big drivetrain noise, the engine had stalled and the back wheels locked up, maybe only one wheel at a time though since it was an open wheeler diff, but I was on the 3 lane wide ring road with no other cars around, and it was almost like just pulling a high speed handbrakey, pretty wild, after a few seconds I'd slowed to about 60kmh and I put it back in neutral, started the car again and kept going.

I'm not sure if a standard car would be able to, if you put your foot down while doing it, be able to arc it up in reverse for drift techniques though.

He wasnt the only person to see it ;)

In fact it was shown more than once :lol:

[Devil CV8]

I know what happens when my VY gets chucked in R at 60km/h........ absolutely nothing..... So voodoo is correct about the failsafes, although they may only exist on the electronic versions of the box.

the wife done it once in the stato on the freeway on the way back from adelailade over christmas and the same happened the engine stalls till it stop's. Restarted the car and couldnt tell that anything happened...
Lucky for her. :lol:

.

done that too....... major Cringe factor hearing those teeth trying to lock, but no damage

I guess the fail-safes were removed in that car then.

Its fairly obvious that you would travel back in time :rolleyes:

[uterus]

Done that once..(suddenly you put the gear in reverse) not sure how fast I was going but it broke all engine/gearbox mounts. When we lifted the bonnet to look the old red motor was laying on its side...

Thats what i wouldve thought, you can even get electronic lockouts on reverse in manuals now

[team illucid]

I saw it at tarmak dragway in about 1997 ... yellow LH torana finished his run and on the wind down somehow hit reverse ... front locked up, front left tyre blew and the car flipped and rolled ... the driver was OK, but the car was absolutely f@##ed ...

[ssvyredute]

when you guys go from 3rd to d why do you press the button.it is not required for this shift.if you don`t do this you will not go into reverse!!!!!!

Well, you should stick your head inside a 4L60E and see how it works, rather than theorising it off the internet VooDoo. So, here is the question, am I lying as you suggested.
I have about 20 witnesses off this forum that saw this happen...just over 35 times to be precise :lol: :lol: :lol:
Back to the search function on Google for you son.

[VooDoo]

So are we talking a car with the safety features removed or a normal car tuna?

I dont need to theorise Tuna, Ive personally done this to my own car and nothing happened. Others here have done the same and nothing happened. Some found the engine died.

Now seeing the majority of people on this forum wouldnt remove these features and dont have dedicated drift cars if say that your example is not the normal response from the auto and hence your reply inaccurate. I dont think your lying, rather not accurately answering the question. But then your good at that. Now go find those manners, you seem to have lost them a long time ago.

[Martin_D]

VooDoo, it was a totally stock car
Again, there were a bag of witnesses from here
You are wrong...admit it and get on with it

[VooDoo]

Strange then that my own car, all the other ppl that have posted in this thread and GM themselves state there are failsafes in the box to protect it against engaging reverse when traveling at speed (forward). Try it yourself some time. Holding your foot flat and engaging reverse isnt exactly normal practice.

BTW, how do you fit 20 witnesses into a car to view this driving technique??

[Rt!]

did it on a V6 once, the car spun
(and stalled)

[Martin_D]

It was about ten trips I reckon, freighting ppl back and forth. At one stage there were 7 guys, each around the 100kg mark in the car/wagon.
Maybe, we all made it up, just to spook you Voodoo......

[RARASV8]

i think it was in 92 but we had a CAMRY hire car and at 130 km/h hitting reverse in the auto was like engaging neutral nothing happened, put back in d and of again as normal, but on a side note same car with air cond on freezing and about 5 degrees outside at 100 then turn heater on causes a very quick stop!!!!
fogs up super quick :confused:

[VooDoo]

maybe not all auto's are made the same.....

[Haroc]

Keep it clean gents or it will see the thread closed.

[eric]

just dug this out of the workshop manual seems that the pcm has an abuse mode doesnt state anything about going from D to R though. hope it helps. :cool:

[SV8VY]

Did it in a sigma once and it got stuck in reverse.
I was young and dumb and I started driving in reverse to get home.
After about 4 km I was pulled over by police and then after a lecture and he went I continued.
I had a sore neck for a few days :lol:

[Nawdy]

Happened to me once when driving a Charger with a 360 fitted. Doing about 40km/h through the local main drag, mate grabs the gear shifter, selects R for race - next thing I know I'm off backwards whilst driving through tyre smoke and axle tramp. Thankfully, no one was behind me.

Thankfully did not damage to the car but it did damage my ego, and it was the last time he got in the car...

[VRIIClubby]

had a few mates do it years ago VS models, and nothing happened at all, a fwe of them stalled the others acted just like it was in D whilst trying to think what it had to do...
