The gears should be a high quality low carbon steel that is surface hardened to HRC58-62. The bearing needles and pins are typcially SAE52100/100CR6 or equivalent through hardened steel brought up to HRC58-64. All surfaces must be ground to size and super-finished beyond the quality that a...

I'm curious, why would it be in the PCV design? My assumption was high head temp differentials, low overall volume and long change intervals combined to make the prob. I had a 1.8T in a 2000 Passat and it developed sludge. I ran synth and did my own changes every 5,000 miles. (You would...

I started my MBA in 1995 a couple of years after finishing my BSME. I took it easy for the first 5 years; one class per semester and occationally took the summer off. I buckled down in the end as we got in a family way and finished in 2002. Any illusions I had regarding a dramatic change in...

Thanks, I'll take that as a compliment. I spent a 7 years in night classes working on that stuff. I'm a mechanical engineer but I finished a Finance-MBA a couple of years ago. The darndest thing - just like my bachelors, it just created more questions than answers. I have the chance to put...

There are other issues at stake here, issues closer to the American consumer's heart... 1) Our economy is balanced between massive investment coming in and a massive trade deficit. Money flowing into and out of the country must be balanced to zero so if one half fails, then so does the other...

HD2, I went back for an MBA while working 40+ hours per week. It took me 7 years to complete 60 hours. While the company paid for the degree, there is a disadvantage... Working full time you can not participate in any internships. If you are looking at leaving your company or industry, good...

I graduated with my BSME in '93. In '95 I started working on an MBA and finished in '02. It took seven years but I got my employers to pay for it. I have already started thinking about PhD but there is one problem - I can't quit my job to do it. You can get a Masters in whatever while...

I work for a German automotive supplier. Having a that DR. in front of your name here is akin to the star-of-greatness. We hire them all the time and they are quickly moved up the ladder to senior manager positions. I would guess that ~40% of our senior/executive managment has that doctorate...

I can help compare Law and an MBA. My friend has been working on his law degree for a couple of years. He has two more to go. Normally the program will take a minimum of three years and cost a bundle. He has choosen to work on the side. It streches the course load out for an extra year -...

I had some spare time at work around the time when "The Day After Tomorrow" came out - so I spent a lot of company time surfing the Internet for information on global warming & ice ages. I would like to ask for comments regarding a different spin on things. What if we reduce the question of...

The only reason a company would pay more, is that they believe they are getting more. The values of US engineering would be closeness and perceived quality. Both of these have a dollar value for any given project; consequently when they add up to less than $45, outsourcing is justified. The...

Mike, you're correct on each count of course. If we try to design stuff that won't fail under the foot of a 95th percentile driver we'll mostly succeed. However, if somebody increases torque into the 4L60E by 25%, I would expect the transmission (bearing) life to decrease by about 1/2 - and...

Paddle-shift was originally intended to allow very fast gear changes under aggressive driving conditions. With your hands on the wheel you can use paddles to shift gears in similar fashion to how you use your turn signal. You find them in Ferraris, M3s, etc. BMW people are now retrofitting...

It seems clear to me that somebody can rig up a sport shift or possibly paddle shift; if you think a sport shift is cool you'll love a paddle shift. It's all a matter of tricking the electronically actuated hydraulic valvebody into thinking you've moved the shift lever. With enough money...

I agree that the ECM is probably a killer. There are similar situations where people want to switch over to a manual transmission. It is easier to transplant the engine and transmission complete from a manual donor vehicle than just swap trannys. Perhaps this would work for you - the 2004 4WD...

I understand what you are doing. As a warning, I seem to remember a Borg Warner patent protecting this very idea. You may look into using in-production automatic transmission carriers that can be purchased from any auto dealer. For prototyping I think this is the only cost effective way to...

Two questions that go together - how fast do you want to go? and how much money you got? It is possible to increase the life of gears but most options are not realistic: *Use a super-clean steel - CEVM or low oxygen content *Super finish - surface fatigue is directly related to contacting...
