How bad would this be for an XJ

[Jeep89]

How bad would it be if someone were to accidently shift into reverse while driving at say 30-40 mph? How would the vehicle react and what warning lights would/should trigger from this? (My friend says he does it all the time at work, where he drives cars)

[PosiDave]

most cars have a sensor or some b.s that won't let you shift into reverse. you can kdrop the tranny doing that, screw up the engine, etc. try running full speed and someone trying to switch you into reverse see how you would react and imagine.

and some people say im nuts for trying to get all 4 wheels spinning in 4 high.

[JohnX]

Cant say for a jeep, but I did that acciedentally once.

50 mph in a 69 El Camino, 400sb, th350 auto. I was trying to pop it into nuetral to rev the engine at a freind of mine. Slipped into reverse right as I hit the gas pedal. Tires Barked pretty loud but didn't do ANY damage. This was not a stock vehicle though, I had a shift kit (which allowed me to shift into any gear at any speed), a built rearend, driveshaft, trans, poly mounts, etc, etc.

I wouldn't reccommend doing it for kicks. Even if nothing breaks, it could send you for a slide in a jeep(maybe even a roll)

[JohnX]

BTW...where does he work...I want to avoid it.

i have done it by accident onec doing 25-30 it just made this popping noise like it was some kind of saftey thing. once i slowed down enough it stopped poping and ran fine in reverse. and i can shift through all gears at while moving. thats like if you hook the front wheels up on certin rwd cars. after you hit 15mph the wheels unlock and spin.

[UNCC_99XJ]

I'd also like to know where he works so I too can avoid it.

Can't say i've ever thrown it into reverse at 30 or even 40 or 50. The most i'm moving when I hit reverse it maybe 1mph, and vise versa when going from reverse to drive.

[90xj06]

hey atleast i live all across the country. :)

[Steev]

Was in my friend's bronco and he dropped it from drive to reverse at about 35mph.. stalled the engine instantly and left a 6 foot patch of rubber..

Truck started and drove fine .. still running now..

[90xj06]

over all it just sounds bad but it sounds like they antisipate this.

my brother accidently did that to a volvo not sure how.
probly going faster than 30 idk.
all the lights came on and it completely shut off. started fine no problems afterwards.

[Jeep89]

Ok so I guess hes not f-ing cars and stuff up too bad. I don't want to tell you where he works because I'm sure that could backfire on him. He said nothing happens but i figured there has to be some long term consqequences.

[Oizarod115]

this is why i fear more than anything else... handing the keys to my 4.0 5spd MJ to anybody at a parking place or anywhere to work on it.

terrifies me.

[GermanXJ]

Why would you want to?

[GermanXJ]

Im with ya Oizarod115.

[Jeep89]

No worries, he works at a car dealership. A mostly new car dealership too which is what scaresme/pisses me off. He got in trouble once because the abs light came on in a honda (i forget which model) after he did this reverse stunt. He says its fun to do in the rain.

[Saudade]

So he goes around trashing NEW cars?

[Jeep89]

I guess so if oyu want to put it that way. Don't get mad at me its not like I'm the one doing it.

[BigG]

i did this about 7 years ago in my '96 XJ. Was coming over a pass in Colorado and shifted in the wrong direction on my AW4. The engine just stalled out an I coasted to the shoulder. no power steering or braking on a mountain pass sucks. Anyway, once I was stopped, the jeep started back up find and has been running fine ever since.

I've got to work in SF every now and again, and the parking lots there tend to "double up" and want your keys.

Funny thing - I give them the keys, but they still can't start the rig (and that's the way I like it.) I don't even take it in for tyres - that's why I have a set of spare wheels. Smog check? Thanks, I'll sit right here and do what you need done, but you don't operate my vehicle (and read the work order - I crossed that line out, and showed it to you before I signed it...)

There are not a whole lot of people I trust with my truck. I can count most of them on the fingers of one nose...

I call BS. New cars will not allow this. I had a 2001 Chevy Malibu as a company car. Driving at 50+ mph (or whatever speed), you could put the auto in 1st and NOTHING would change. It would act as though it was in drive until your speed was low enough to accept being in 1st gear, then it would downshift. Never tried reverse, but I bet it would be the same.

[Jeep89]

I thought there was some time of limiter on this too, maybe he is bullshitting me, but whenever we are driving hell be like thos skid marks are from me. Maybe just lieing to be cool. Maybe he only does it with the 50 or so used cars they have at one time. I'm not sure.

[-96JeepSpeed-]

I acculay did that on accedent doing about 40mph. The rear wheels just locked up and skidded about ten feet before i shifted back to drive. not one thing happened though.

[ChicksDigWagons]

Let me just say that your friend is an Asshat and I hope he gets fired. Nothing good can come of those kinds of stunts.

yes, this would happen on 1-2 on newer cars. but not on some older ones. the easiest way to shift from drive to neutral. is just pull the handle not pushing the button. and this way it will lock into neutral. same for reverse.

Amen!

A friend of mine owns a 1971 DeTomaso Pantera... took it to the stealership (Lincoln/Mercury!) for something or other back when it was still nearly new. One of the lot jockies managed to break an axle shaft whilst dickin' around in it.

Dealer had to pay to ship the entire tranny/axle assembly to ZF in Italy for repair.

Probably was a bad day for the employee.

You design a low-gear "interlock"... because you assume some bonehead will yank it into 1st at 75mph.

If *I* was an engineer, I wouldn't anticipate that some bonehead would throw it into reverse... and sure heck not deliberately!!

Confession: I did it in my '84 Olds Omega... my first car. Column-shift. I had been in low gear, then "overshot" when putting it back in drive. Scared the living crap outta me (a tranny overhaul woulda cost me more than the car did!)... but it restarted, and never showed any ill effects.

my brother accidently did that to a volvo not sure how.
probly going faster than 30 idk.
all the lights came on and it completely shut off. started fine no problems afterwards.
Volvos are good about shutting down immediately if anything goes wrong that could damage the engine. What probably happened though is that the computer shut the engine off and that turns all the dash lights on.

On one of my old cars was a Volvo and I blew a heater hose going down the interstate. It began to overheat very rapidly and it was touching the edge of the red before I could get to the right and off the road. It went from straight up and down on the gauge to touching the red in less than 30 seconds. The second the gauge touched the edge of the red, the computer shut the engine off. It wouldn't restart till after the engine had cooled down. I thought that was pretty cool since most cars won't do that.

I agree. I hate people who don't respect others property. No car deserves treatment like that even if they are a Honduh.

For those who do it accidentally, I'd think that there'd be a bit of accellerated wear on the clutches and bands in the tranny and probably a little burning of the ATF in the torque converter.

when my 300zx stalls all the lights come on.

[ktwalker01]

I was with a friend once in a 5.4L Expedition and I have no idea what he was thinking, but he ment to shift it into netural and Rev the engine by some people, but put it in reverse by accident and reved it while doing around 35 the back end started bouncing around and going nuts.... Pretty scary, didnt hurt the car at the time dunno what to say 80K down the road and the engine didnt kill itself he just put it back into D.

[muduck18]

i did it once on a ford escort because i wanted to see what it would do, From that day forward it would not lock the car in place when i park.

it made the same clicking noise that it does when you plug it in to park while moving.

i think that the effect on the tranny would differ according to the age and strength of the tranny...
