I could definitely go from 6th to 2nd in my last two cars (latest is a 2017 Mazda 6) if I slow down rapidly enough between the change. However I definitely do not recommend it as it means you didn't plan well enough for the corner you need 2nd for. In most gearboxes it is only the synchros that stop you changing, if going too fast for the gear it will "try" to prevent you changing down but you can still force it in.
Yeh, I don't know of any manual gearboxes that would physically prevent you changing down even if caused an over-rev other than being hard to do it.

the same way you can't select reverse

i just find never skipping gears helps to not select the wrong gear

5 speed boxes always self centre

pretty sure 6 speed boxes don't when going 6 to 5 (to avoid 6 to 3) so if doing 6 to 4 maybe people get in the habit of forcing the stick across from the RH set to the middle set of gears.

so then in 5 and selecting 4 but force it across you could select 2 quite easy

If you're brutal enough you can select reverse. It's easier if reverse is synchromesh, but either way it will go in. Certainly any of the forward gears will go in, although if there's enough of a speed difference; the baulk rings will try to prevent this until the layshaft (I think I have that right) is up to speed, although it is possible to force your way past them.

I drove with a staff member from one of my clients some years back in a Transporter van. He was by far and away the most mechanically unsympathetic driver I've ever had the misfortune to be with. As we approached traffic lights or junctions at 30 plus mph, he would just shove it straight into first gear.
From my position in the passenger seat I was wincing at the whining and shuddering as the gearbox was spinning up to high speed in a very short time.

Fortunately he wasn't quite stupid enough to let the clutch out at this speed, but the synchros must have taken an absolute battering. I actually mentioned to his boss that he needed further training as it would cost them a lot of money in wrecked mechanicals.

Sounds like a friend of mine who will turn the car off, let it roll to a stop and just pull the handbrake on when it's still rolling to a stop. He'll be out the door before the engines even stopped. haha

1. Accidental gearchange breaks engine (maybe)
2. Car owner gets new engine

And they all lived happily ever after.

The end.

If only it was the end of this thread.
This. The speed with which they obtained and installed a replacement engine is quite astounding.

They'll have 'em in central stock in MK, ready for overnight dispatch to the dealer once it's ordered. By the time the engine's arrived, the old one's already out. Two guys on it, and it'll be in before you know it.

Ramps with a dead car on 'em don't make money.

I've tried to change up from 5th to reverse one morning on rhe way to work in the "other car"
(actually a van).
Luckily I didn't succeed.

Not on all cars. It's physically impossible on the EP3 Civic as there is a reverse lockout solenoid on the gearbox that prevents selection of reverse until the car has completely stopped moving for a second or so. Quite an annoying feature tbh, felt like to took forever when you'd met a car coming the other way on a tight country road and you wanted to get it into reverse.

Saw a guy driving a Ford Orion go 1st, 2nd , 1st on a traffic grand prix once, much tyre smoke and the car did a 180.

if i'm slowing from say 30 in 2nd and i push the stick into 1st it won't go.... if i keep pressure on it then it will slip in as i come to a stop

reverse no chance as i have to lift and dip the clutch to go in even at standstill smile

on the 5 series, 6 to 5 the stick stays right quite easy and would need encouragement to select 4 or 3

Thats the baulk rings stopping you. If you slam it in hard enough it will go into first.
Same as being able to do a full power clutchless upshift, I think they used to call it ‘power-shifting, that is, changing gear without using the clutch without lifting off the accelerator.

I don’t recommend you try either of these by the way as it’s asking to cause damage, but it’s possible, believe me.

Interesting thread OP, sorry to hear you are £8k lighter. Hope you get some joy out of VW, it does seem odd to me to get such an overspeed on a downchange, without the car attempting to catapult you through the windscreen.

I keep struggling with this - why do educated petrol heads seem to think an engine is more effective than car breaks?
Next we will see or hints of how to reduce stopping distance “do a money shift” FFS.

Are you hard of thinking or something?

The OP says he possibly stuck it in 1st at 70mph yet didn't feel a thing.
That is at best unusual. That's why people are interested.

I don't have time to troll the thread for hours like you apparently do, but then again you do hail from Emmer Green so I understand there's fk all else to do than get lippy on the internet.

Do you think a money shift into 1st day at 70mph will have more retardation than emergency stopping in the brakes?

A few have posted about what they would expect the impact to be and “face palming” the windscreen would be a possible outcome.

Just spotted your username - I’ve frequented that venue countless times over the decades, likely we have met smile sweet cheeks.

Slamming on the brakes has an expected result, you are thus braced for that effect....try slamming on the brakes or down shifting 2 and dropping the clutch when your wife is doing her make-up and is not expecting it...... and tell me the result.

Yes, you WILL notice it.

9 min 44 secs in and 14.20 in. I suppose we'll find out from his future vlogs what the damage was on the GT86 for a similar mishap.

Make up stick prodding into the eye wouldn’t be nice.
