I've made a few errors here on the boards. I got pretty pissed at myself but a wise old dude replied saying, "Don't sweat it, if you aren't makin' mistakes then you aren't tryin' hard enough." Good advice, eh?

Automatic shifting
This came up in a different thread today and I thought it was another good explanation of what was being discussed here so I post it just for reference.
------------------
There is a problem with torque converters, there always is a slippage. This produces heat from the oil shearing and lowers fuel economy. To overcome this problem, today's automatic transmissions actually have clutches that "lock" the two halves of the torque converter together. You can see this happen on your tachometer when you go into overdrive. It first shifts up into OD, you see the RPMs drop and then it drops some more when the torque converter locks-up.
