RE: proposed merge with Sequential manual gearbox.

YES these articles should defintely be merged. they're about exactly the same thing Spute 20:10, 30 January 2007 (UTC)[reply]

No, it should be merged with semi-automatic transmission. A sequential manual gearbox like a motorcycle's is a completely different thing, from both a mechanical perspective and in the way its used. 66.108.15.120 02:12, 14 February 2007 (UTC)[reply]

This is total mess, there is 4 or more articles with same stuff:

http://en.wikipedia.org/wiki/Semi-automatic_transmission

http://en.wikipedia.org/wiki/Electrohydraulic_manual_transmission

http://en.wikipedia.org/wiki/Sequential_Manual_Transmission

http://en.wikipedia.org/wiki/Sequential_manual_gearbox

dont know what the article name should be, maybe robotized manual gearbox, its often named also as sequential manual gearbox ala BMW SMG.--Typ932 00:08, 19 March 2007 (UTC)[reply]

A semi-automatic transmission is an automatic transmission that allows the driver to control the gearbox. Semi-automatics use a torque converter instead of a clutch. An electrohydraulic manual is a manual transmission with an automated clutch. Transmission and gearbox are synonyms, and should be merged. Whether transmission or gearbox is used in the title is arbitrary. We should end up with 3 articles: one about automatic transmissions that the driver can control (semi-automatic), one about manual transmissions that are shifted or clutched automatically (electrohydrualic manual or automated manual), and one about true sequential manual transmissions, with a manual clutch and manual shifting, called sequential manual transmission or gearbox. 192.156.52.34 (talk) 18:15, 24 June 2008 (UTC)[reply]

This is a mess somewhat larger in scale than what has been discussed here. The more fundamental issue of the proper use of the term 'transmission' (which is partially discussed as a British vs. American terminology issue in the Transmission article) aside, the term 'Sequential' refers to the way a gearbox 'shifts' in reduction/overdrive ratio. And shifting is a secondary function to the primary function of speed reduction / torque multiplication and the way a gearbox 'transmits' the power with a belt/pulley, chain/sprocket, fluid coupling, gear/shaft, etc. When an user thinks of a transmission, the way it 'shifts' may be more important than how the box converts a high speed low torque power into a low speed high torque form, but the latter is a far more significant issue from an engineering stand point.

As an example, a typical "sequentially shifted" motorcycle gearbox can be made to allow random access to several gear ratios by adding some means to move the shifting mechanism multiple times with a single shifter motion in different directions. Do we 'not' call it a sequential gearbox despite the actual shifting mechanism inside the box operating sequentially? Or should it be called a 'semi-automatic' gearbox as one longer throw of the shift knob is automatically converted to several shorter clicks on the box with a spring? What if this conversion is done with a help from electric motor which also operates the clutch?

As such, a clean categorization would be difficult without adopting an engineering point of view with its associated stricter definitions of the terms, which would likely make finding an useful article impossible, or at the least overly complicated (like finding different descriptions of the term 'automatic' under different transmission working principles focusing on speed and load sensing, as well as under "shifting method" subcategories of each principle focusing on how the mechanisms are operated by humans), for an average Wiki user whose usage of the language and concepts like 'transmission' is quite different from a well educated engineer.

Please tell me if there is a good discussion on this "use of common language on technical concept" issue somewhere on Wiki. Otherwise I'd leave the mess as it is, as someone's Apple (like "transmission and gearbox are synonyms") may well be someone else's Orange here. Yiba (talk) 11:33, 11 June 2013 (UTC)[reply]

Improve Template

I added an improve template due to the lack of citations, I also removed a comment in the page:

Improvement to article

Id like to see a picture of the inside of a sequential gearbox. Something like one just broken open, I couldnt find one that wasnt free to use. If anyone can find one please do. — Preceding unsigned comment added by MWright96 (talk • contribs)
