Great job on the Tranny filter. I mangled the drain bolt on mine, time for new tools. I'll go through all that trouble and not be able to get the old seal out...

Should have dropped me a line, I've got a great little tool for getting that thing out.

What did you use, a BFH?

Wingnut · August 16, 2005

Yup...Just beat on it until that little gasket fell out along with all those nuts and bolts that my tranny didn't need anyway.

Seriously though, I have a couple of little doohickeys that get up in there and pull it out with minimal fuss.

Good write-up. The only thing I would change is the explanation of the diode. The diode is passing current , not voltage.

Thanks, there is also a missing word that I caught, but lost it again!!!! grrrrrr Anyway, there is a missing word.

Regarding the current / voltage. Academically, that is true and that also probably needs to be changed. However, you put a voltmetter on a diode that is blocking and you are not going to read anything, nada. No voltage. Nothing. I just wasn't think that academically when I typed that article up.

Hmmm. If the diode is in series with a load, and is reverse biased (i.e. blocking), the full voltage will be read across the diode. When the diode is forward biased (i.e. conducting), there should be about 0.6 volts read across the diode (for one made of silicon), and the rest of the voltage will be read across the load.
