    Naming problem (hydraulic transmissions)

    Thanks to all, that was enlightening :-) I decided to go with Fabrico's first suggestion. I'll call both types "automatic transmissions", and where I need to make a distinction, I add "automatic shift" or "manual shift" as appropriate. This seems to be clear enough and in line with the...

    Naming problem (hydraulic transmissions)

    Oh, and in case that wasn't clear to everybody: this is meant for a US target audience.

    Naming problem (hydraulic transmissions)

    Thanks, Fabrico. So basically, "automatic" means something like "has a torque converter"? I'm not sure I can get myself to like the "manual automatic" transmission :-)

    Naming problem (hydraulic transmissions)

    Hello all, I've got a problem with naming of hydraulic transmissions. This is in the context of a manual for an aftermarket item that works with both automatic and manual hydraulic transmissions (or maybe better, what I call "automatic and manual hydraulic transmissions" [smile] -- see below)...

    Speed estimate from rim deformation?

    This isn't the case of a wife, but close :) I have been in (deep) potholes, ran over rocks, with reasonable speed, and never managed to damage the rim severely. This is the worst I've ever seen in front of me (but I'm not having much experience with this sort of thing). The whole situation, how...

    Speed estimate from rim deformation?

    Thanks, Greg... I guess that would be the most accurate method, but I'm not sure it would be the cheapest :) I guess what I was hoping for is a collection of pictures of damaged rims with a brief description of how it happened and at what speed -- just to give me an idea of what might be...

    Speed estimate from rim deformation?

    Hello, can anybody please point me to something that would help me estimate a minimum impact speed that would have been necessary to cause the deformation of a (steel) rim? It's pretty badly hurt... Thanks, Gerhard

    Control freewheeling in GM transmissions (4L60-E)

    ircman: Again, I'm not really a transmission engineer and can't say that I've understood all the inner workings of this transmisson... But it seems to me that the main part responsible for freewheeling/coasting is the forward clutch sprag assembly, not the lo roller clutch. And the forward...

    Control freewheeling in GM transmissions (4L60-E)

    Literature I have: GM Powertrain: Hydra-Matic 4L60 Technician's Guide Second Edition, 17001.11-5, HM-4L60-TG The overrun clutch is a clutch pack controlled by hydraulic pressure. It is controlled by hydraulic logic, mainly through the manual valve. It seems the consensus of this thread...

    Control freewheeling in GM transmissions (4L60-E)

    shootfromthehip, a very simple solution (some electronics required): 1) Gear control: Somehow mix current gear, speed and throttle position together to get shift curves that you can live with. This could be done in a very simple manner with a few opamp adding up appropriately scaled inputs. Run...

    How ethical is it to give and receive gifts

    You guys got me also thinking about collusion. I'm not sure about the ethical aspect of it (again there seems to be the intent thing), but it definitely looks as if most countries consider certain forms of collusion legal and even good or necessary. Starting from the explanation in...

    How ethical is it to give and receive gifts

    Maybe like this: Whether it's ethical is determined by the intent. Whether it's good for the career is determined by the perception (by others, of course). Whether it's legal is determined by the laws (and the perception of the judge or jury, in case the legality gets challenged in court).

    How ethical is it to give and receive gifts

    I'm not sure... The definition of bribery you posted has as one of the prime criteria "in order to influence" -- sounds very much like intent to me. Also almost all the examples cited include the word "to" between the bribe and the returned favor, which also seems to indicate a strong...

    How ethical is it to give and receive gifts

    IRstuff, in my comment I presumed everything was done in a legal way -- as I think up to that post most posters presumed the same. Legality so far wasn't the question; it was what behavior was ethical. Where a clear legal guideline exists, we just follow it. That's probably a consensus here...

    How ethical is it to give and receive gifts

    I think pat has said it pretty well: in the end it's the intent that determines whether something is ethical or not. The other questions -- whether or how much or when and how to accept favors or when something becomes an unacceptable bribe -- depend so much on society, company culture...

    How ethical is it to give and receive gifts

    Well, my point was that there is a sometimes large grey zone with issues like "preferential treatment" and "better personnel". What makes a differentiated treatment preferential? (I hardly ever treat two people the same.) What makes a preferential treatment unethical? (If you have children or...

    How ethical is it to give and receive gifts

    IRstuff, what constitues a "level playing field" or an "unfair advantage"? Probably every vendor I've worked with in the past (if that was successful) has an advantage over a new vendor. Is that unfair?

    How ethical is it to give and receive gifts

    HgTX: "Can one tell when someone is being friendly and when they are, in essence, prostituting themselves?" Probably the problem is not whether one is genuinely friendly or is just faking being friendly, the problem is whether this is affecting your decision to buy from him and if so, whether...

    How ethical is it to give and receive gifts

    pat, While I can relate to most of your post, your comment about tipping in Germany doesn't match my experience. (I'm German, and even though I don't live there currently, I lived there the first 30 years of my life.) The price of the goods in a restaurant include a percentage for service...

    Sequential in Autos?

    Norm, as a side note: I'm not really sure, but I think the worldwide percentage of cars and light trucks with manual transmission is over 50%. AFAIK, the USA is the only country worldwide where automatic transmissions dominate in this market. (But not much known about sequential transmissions...
