Talk:Overdrive (mechanics)

From Wikipedia, the free encyclopedia

Hi: I need to know when would it be apropiate to use the OD on or off, I live in Mexico City a very crowded town but I really dont know when to use the OD on or off, should I turn it off inside the city or what.

THANK YOU I'll WAITING FOR YOUR ANSWER.

Rafael, 99% of driving should be done with the overdrive enabled.

Coming at this as a clueless person, I didn't understand one thing after reading the article: How/why can overdrive be engaged without using the clutch? Good article otherwise.

I thought the same (my father had a Volvo 740 so equipped) the best answer I can offer is that the gear engages rather like the gears on an automatic box. So I can say why, but not how, sorry! Alastairward 11:22, 2 February 2007 (UTC)

[edit] Bias Toward Automatic Transmission

When reading this artice, I notice that manual transmission was only mention once, with the remainder of the artice favoring OD in automatic transmission. I think this is Bias. --KB1KOI 15:32, 28 July 2006 (UTC)

[edit] Bias towards automatic transmissions

I do not believe there is a bias in this article, as in the manual transmission, the overdrive gear is treated like any other; while in the automatic transmission, it is usually electronic and switched on or off with the press of a button, but generally is not usually interfered with.

[edit] not bias

one of the reasons that this article may seem bias is becuase the automatic engine, switches to OD automatic-ly hence the name, where as manual you have to actually put it into OD

[edit] Rename Page?

I'm trying to find consensus for renaming "(mechanics)" pages, where "mechanics" refers to machinery, mechanisms, mechanical devices or mechanical engineering, rather than (e.g. classical) mechanics in physics and applied math. I would like to rename this page to "Overdrive (mechanism)" or "Overdrive (mechanical device)" or something similar. Any preferences or objections? Geometry guy 20:57, 21 February 2007 (UTC)

[edit] Drive train wear

I don't know a lot about mechanics, but the section in this article on drive train wear didn't make sense to me. Unless using an overdrive gear means you are going to drive faster than you have would otherwise, why would there be more wear on the drive train from using overdrive? i.e. isn't drive train speed fixed to vehicle speed?
