Gears being pushed around by fluid instead of a direct mechanical connection. All of the "fancy" stuff in an autobox is related to the valve and solenoid system that pushes the gears where they want to go, and can be ignored if you're just trying to get a grasp on their basic operation.

Yeah, I'm mostly a "remove and replace... with a manual if possible" kind of guy when it comes to autos. Things that involve black magic: differential R&P setup, auto transmissions, 80s GM tilt steering columns. Soon as I pick up a few more tools I'm going to start learning how to do differential setup, but the others can go to hell...

Auto valve bodies are basically a hydraulic analog computer, so I SHOULD understand them pretty easily, but every time I look at one, it's just an utter mindfuck. Gear setup is one of those things I think I'll enjoy once I have the tools and a little experience.

But that valve body  I'm guessing if you were designing a simple transmission with only computer control, no concern for smooth shifting, and no throttle/speed feedback or anything you could make one with just some solenoid actuated valves coming off a manifold but drat if that isn't a hydraulic maze and a half.

KozmoNaut posted:Nah, but being a dick about it is a terrible thing. The red light creeper thing was relevant, getting all high and mighty because you drive a car with a "real" transmission wasn't. Yeah I wasn't gonna mention it there since enough people in that thread called him out, but he did come across pretty full of himself. Especially for a supposed VAG fan who are doing such great things with DSG, acting like manuals is the only way a true driver can experience the road comes off pretty elitist for an activity that should be more about having fun.

I've also found Ate Up With Motor's history of auto transmission development to be useful in understanding slushboxes and how the modern design came about (be sure to read pt 2 aas well.)

I had an early 90's Haynes Manual for a MK4 Ford Escort (it was my first car and it was an RS Turbo replica ok) and it went through how to rebuild the gearbox and stuff like that. When it finally died a death that was suprisingly not me rolling it like most 17 year olds I picked up a brand new haynes manual for its replacement a mighty Nissan Bluebird (stop laughing at the back it was a ZX Turbo!) and the whole gearbox section had been replaced with that kind of stuff. I find it highly unlikely rebuilding a Ford gearbox is going to be much different than a Nissan one so I can only conclude they started removing stuff like that due to stupid people ruining their gearbox or because the Shadowy Mechanics Union got to them.

I'm guessing they're all visually impaired from the way they parked. I had a terrible car stuff encounter last night at dinner. No pictures sorry. I'm eating my dinner when the four people at the table next to me loudly begin arguing about cars. More specifically, street racing. What followed really was like "VTECKICKEDINYO.GIF" in real life. Highlights included: 1) What speed you needed to be doing before the cops wouldn't chase you further. 2) Who's car is louder (Because loud equals fast you know!). 3) Remember that time I did that mad burnout and hit the telephone pole? As I left, I decided to go for a walk thru the lot, figuring I could pick out which car was theirs. drat it was simple. Early 2000s Civic Si, in good shape actually. Naturally, it slammed with a "racing" steering wheel (who needs airbags?) with purple metal column and the worlds largest sticker with the name of their "racing" shop on the side. They seemed to be finishing up, so I made my escape before I actually had to operate a motor vehicle in the vicinity of them. Aurune fucked around with this message at 18:44 on Apr 14, 2013 |

Highlights included: I have no idea why this is such a popular subject among brainpower-challenged car guys. It always seems to come up. Yeah, everyone knows that Danish cops usually don't give chase above 180-200kph or so, the idea being that they would simply be further endangering everyone else on the road. That doesn't mean you can outrun them. Ain't no car or bike made that can outrun a Motorola.

Not that I condone it, but I've gotten away a few times in the past. If you're in the right area and have a head start it's not that difficult. I only mention it because your post makes it seem like running is totally irrational and will always fail.

Honestly, if you're in a situation where you're being chased by the police, chances are that you did something really stupid and illegal. Don't do that and you won't have to worry about outrunning the police.

I think it was more like I'mdeadI'mdeadI'mdeadI'mdeadI'mdeadI'mdead than anything. If you've been on the Dragon, you've seen there are many places where if you go too fast into a turn and understeer through it, you are ramping some serious airtime into serious dead time.

You'd be surprised how little a 2.5/5 pound extinguisher will do, especially when you have no access to the underside of the car where it's setting things on fire. Carry a bigger extinguisher. Like, at least a 5 pound strapped down anywhere within reach (while belted in), another 5 or 10 pound within reach from the front seats, and preferably a larger one elsewhere as well. A fire sometime last year burnt one rear corner of a friends jeep, sent a friends wife to the hospital with burns to her feet, and took nearly 30 2.5-pound extinguishers to actually put out. If they hadn't been at an offroad park with lots of people carrying extinguishers (required equipment by most parks and clubs) around them, it probably would have been a total loss. Also, that's on a big jacked up jeep, getting at the fire is obviously much more difficult on a sportscar/lowered vehicle, especially one that's slid off the road and buried itself on top of an embankment. Hell, I carry either a 10 or 20 pounder (I forget, it's the big kitchen size one) in my pile of poo poo jeep, I generally carry two but haven't replaced one after using it up a while ago. kastein fucked around with this message at 14:37 on Apr 15, 2013 |

trouser chili posted:Hi, my name is Trouser Chili, how would you like to take a drive with me? I think it's quite, I don't know, rewarding, I suppose, to have someone complain that their basic car is too slow, and be able to show them that there's a whole 4,000rpm they're not using, and actually it'll make quite decent progress if you grab it by the scruff of the neck and make it work. That there's no magic to it, you can learn to extract what performance there is and make the best use you can of it.
