That is what happens when you try to be a wise guy, but I was surprised how closely packed the street was with cars, there is not a lot of room.
Simon: Nils? You can close in now. Nils?
John McClane: [on the guard's phone] Attention! Attention! Nils is dead! I repeat, Nils is dead, ----head. So's his pal, and those four guys from the East German All-Stars, your boys at the bank? They're gonna be a little late.
Simon: [on the phone] John... in the back of the truck you're driving, there's $13 billon dollars worth in gold bullion. I wonder would a deal be out of the question?
John McClane: [on the phone] Yeah, I got a deal for you. Come out from that rock you're hiding under, and I'll drive this truck up your ass.

Avoid reverse loads through the transmission?

Avoid engine braking?


No way man! Saves on the brake discs. For me, it also balances the car very differently.

i.e. going out of a motorway, without notice it so much your revs could go very high

Partly agree :wink: I would say don't use the clutch and engine braking to slow the car down. Sure, once the clutch is fully engaged use what the engine gives you.

I would rather fit new pads than a new clutch & busted diff.........

Why not?

The clutch won't notice which way the torque is transmitting through it.

The diff shouldn't be affected.


Use engine braking on the tractor all the time - indeed, everyone driving a tractor is the same, doesn't do them any harm.



As said though, riding the clutch will do damage.

Unless someone can tell me otherwise, he's my understanding.......

As parts get used, they become "happy" with accepting loads in a certain direction (gear teeth for example); sudden and violent loads in the opposite direction do them no good at all and you are more likely to get a part breaking.

It's not just the transmission that tries to reverse itself, crank, pistons, cam, rockers - etc. etc.

I view it as putting loads into bits that would be happier not having to do that work.

BTW - I drive cars with more delicate transmissions than a tractor ;)

I raced 2-strokes for years, so I admit I'm possibly a bit OTT in that department. A pre-mix MXer might "nip-up" a bit if you used the engine as a brake..... :shock:

You're right :D ! I do it often and my litlle 1100cm3 beats every other car in line! Lots of people try to get off fast, but they do it from low revs and loose ages!

When you do a "school driving" they tell you to brake very little and then use gear to slow you down. That ofcourse applies if you are slowing down gradually, not doing a bloody emergency stop.

btw. That guy on the video is n00b from my point of view. Usually if you're car doesn't have ABS, then you must not allow your wheels to lock, if they do then release the foot and apply again, otherwise there is no control. Maybe this video isn't a proper example, but I'm sure that many of you experienced sudden braking and most of you know what I'm talking about. :)

I had brake failure in a race reacently and the only think I could do was slam it into reverse. It didn't help the transmission but you get away with it.
this isn't a usefull practice

The old Gilles Villenurve theory 'theres always a gap.'

The only diffenence being he knew mentally exactly how much room he had, exactly how big the car was and could feel instantly if the steering got light or if he was taking a turn too fast.

What was you driving?

Cars dont usually have synchrones in reverse gears, so I'm confused.

I held a few people in high regard on this site but reading how you all drive make me laugh my nuts off. can't drive with a manual (stick) hahaha the rest of the world can drive a manual and auto's without a problem, no wonder north americans can't do F1 or WRC (thats sarcasm before you all get offended).

when you stop at the lights for starters don't use the engine to slow the car down thats what the f**king brakes are for and dont change down through the gears either.

before you come to a stand still engage the clutch to stop stalling and when you stop lift up the hand brake and put the car in neutral. remember a womans t-shirt, you always lift up before you wobble (if it a manual and not a sad auto).

pay attention to the lights and if you can see the other light changing from green to red you can anticipate your lights, so as yours turn from red to amber get into first gear and have the clutch biting and when it goes green give it some.

dip the clutch thats the best thing to do or turn the engine off but not all the way so the steering lock doesn't come on
