[AT] Transmission oil, 90-wt?

[John Hall]

Speaking as someone who makes a living by constantly switching back and 
forth between English and Metric, I say get educated and learn how to use 
both. Then you can learn about British pipe threads, Japanese pipe threads, 
British conduit threads etc. It doesn't take a rocket scientist to be able 
to use all systems---just a willingness not to be so lazy as to refuse to 
learn something new.

Just my opinion and probably worth about half what you paid for it!!!
