Talk:Manual transmission

message: This is not a neutral point of view of manual gearboxes. Looks like a sales pitch for automatics. 
Where are the discussions about the advantages? Why racing cars / drivers do not us automatics ? Heck most bikes are manual!
Race drivers, truckers use manuals because with an automatic you cannot control the RPM (hence the power) going to the wheels as you shift. Period end of the story.
With a manual you set the exact RPM to the wheels as you shift, which is critical for performance driving at the track or the streets, what ever -
Try rowing back 2-3 gears and spinning wheels with an automatic ....
How is it possible that the "Driving techniques" sections starts with "Driving a vehicle with a manual transmission is more difficult  ..."
That is a BS personal point of view. I have a manual and automatic cars and on the Highway I find the automatic way more complicated because I have to deal with not knowing when shifts are done/power delivered to the wheels. With the manual I select the power and let go of the clutch (if that is needed ... )
This should be an article "about" manual transmissions ...  let us remove all the unnecessary references to automatics.

thread_title:  This article is not NPOV 

message: "This is useful when the vehicle will not start, but must be immediately moved e.g. off the road in the event of a breakdown, if the vehicle has stalled on a railway crossing, or in extreme off-roading cases such as an engine that has stalled in deep water."
Starting a car that has stalled because it sucked up water will break the engine. Water is incompressible and when a piston is in the compression stroke the water will prevent the piston from moving. However the starter engine has more then enough power to bend/break conrods and I can easily blow the piston out of the engine block  —Preceding unsigned comment added by 122.109.109.133 (talk) 17:25, 1 February 2011 (UTC)

message: This sentence "Manual transmissions place slightly more workload on the driver in heavy traffic situations..." was incorrectly placed under Benefits when it's clearly a drawback of manual transmissions. I've moved it to the right category.  —Preceding unsigned comment added by 85.74.77.242 (talk) 10:48, 24 January 2010 (UTC)
thread_title:  Moved a Benefit to a Drawback 

message: In my humble opinion, this section contains too many weasel-worded statements like "most heavy-duty transmissions are non-synchromesh." How many is most, how many kW and Nm is heavy? Its point of view is also not neutral but biased towards Nort America. I cannot give any numbers but definately most lorry transmissions are either synchronised or automatic in Europe.

replies: text: Steep hills are an extreme case that do not disprove the statement, and if the load (on level ground) is particularly heavy or if the ground is soft, you'd use low gear. For a normal standing start you'd just let go of the clutch, which makes the statement completely correct. Why you think it's wrong because you handle an extreme case differently is beyond me. --204.191.135.101 (talk) 04:20, 1 April 2009 (UTC)

thread_title: Gear change "Plate"

message: The Porsche synchro was not conical. Instead it used two small curved plates that acted much like a leading-shoe brake to bring the gear and sleeve to the same angular speed. I'll try to dig up an old manual I have and explain in more detail. I also agree with the other talk poster than pictures and animations would better illuminate this subject.

message: The construction of the article implies that non-synchro is equivalent to non-constant mesh (although this point is cleared up in brief in the "Synchro" section).

message: I've been looking up information about crash gearboxes, but there isn't an article at this title, nor do the search results provide an obvious location. I think therefore a redirect from crash gearbox would be a good idea, possibly to the Unsynchronised transmission section of this article or is there a better target?

thread_title:  Crash gearbox 

message: Should this really be mentioned on this page?  The car has an 8 speed semi-automatic, not a manual.  I don't believe it belongs here.  A very crude definition of a manual transmission would be one that involves a driver operated clutch -- the Lexus does not have this feature and relies on torque converters to decouple the engine and transmission.  Since this serves as the basis for the idea that more than 6 forward gears are available in commercial cars, all references to more than 6 speeds should be removed.  Willing to retract this opinion if someone can find a picture of an 8 speed gear shift in a Lexus IS F that does not involve paddle shifters and clearly shows a clutch pedal.  24.218.141.183 (talk) 03:45, 17 December 2009 (UTC)
thread_title:  Lexus IS F 

message: "The NHTSA reports that manual transmissions also result in 37% fewer accidents per mile driven. Experts believe that this is due to the extra attention required while driving a stick-shift. For example, it is difficult to use a cell phone while driving a manual transmission."
"...automated manual and semi-automatic transmissions are becoming more common on heavy vehicles, as they...may improve safety by allowing the driver to concentrate on road conditions."  —Preceding unsigned comment added by 76.244.77.110 (talk) 22:59, 22 December 2009 (UTC)
thread_title:  Contradiction? 

message: The article talks in several places about how R facing to the back is intuitive, and R pulling toward the driver and up on a column mounted shifter is not. All ridiculous. If R is intuitively placed, then 2nd and 4th are counterintuitive? It's silly. And pulling toward the driver on a column mount is toward the back of the car, which I would not call intuitive but whoever wrote it should have. 71.190.72.157 (talk) 22:48, 11 September 2010 (UTC)
thread_title:  "intuitive" 

message: Ok, so the Benefits and Drawbacks Section was rather difficult for me to read, with seemingly no aim, and several redundancies in unrelated paragraphs.  As such, I took it upon myself to re-organize it with a more topic-based approach.  I mostly just re-organized what was already written, but added a couple things that seemed to fit.  I tried adding some citations, but after checking the External links guide, none of them really seemed to be appropriate, so I removed them.  I was unable to find any good cites for anything, but from personal experience I didn't see much that was wrong.  Still, a couple things struck me as odd:
All automatics I've driven have had options to put the transmission into 2nd or 1st for engine braking downhill.  Most have also had the option of 3rd (usually by way of "turning off" the overdrive, which is just 4th gear - though the "OD off" button often changes the dynamics of the transmission as well).  As such, I think the section about "Nissans and Hondas" having such options should probably be generalized to "most automatics" or something similar.  In fact, given that most automatics have the ability to do this (as well the part I added about downshifting to pass in the "performance" section), it might be better to re-word this to something like "it's more obvious and common to do this with a manual".  This last statement is based on many internet posts I've seen asking if engine braking is safe for an automatic, meaning A, people don't read the owner's guide, and B, it's not very obvious to many people.
As pointed out above (or below, I'm not sure which way wikipedia orders these sections), using the starter on a hydro-locked engine can be fatal to your motor, very quickly.  The only way this is useful is if you pull out all the spark plugs first, which also happens to be how you get the engine running again so it can pull itself out of the water.  Furthermore, most vehicles that are meant to be off-roading have winches attached for this very reason.  As such, this part should probably be deleted.  Still, I'm not an off-roader, so it's possible there's something to this--perhaps the water didn't get into the motor because the guy used a snorkel, but the back-pressure on the exhaust is preventing the motor from spinning fast enough to run.
I probably won't ever read this page again, so if you have better ideas or hate my version, revert or change it.  It just bugged me because I was having a difficult time understanding what the article was trying to say here (I also made a couple minor edits to other sections, but just some typos and stuff). 70.190.180.161 (talk) 10:38, 9 March 2011 (UTC)
thread_title:  Benefits and Drawbacks Section 

message: They are quite nice, and surely appear to have been prepared by someone who knows enough. However, they really need to be about twice the size, or more! I find it hard to figure out where the output shaft is, for instance, having a good technical background, but not knowing what's commonplace. I do hope they can be enlarged without becoming too "grainy". As well, a few callouts, such as "Input Shaft From Clutch",  "Countershaft", and "Output Driveshaft" would be quite helpful. Just to give some perspective, I was looking to see which gears were engaged, and it was a lot harder than I think it should have been to find them.

thread_title:  Illustrations at the end 

message: Unless the car comes to an absolute stand-still, there is no need to use the clutch. Usually the second gear has a lot of "range", all the way down to a fairly slow creep. If you do not tail-gate the car in front of you, and look at the traffic ahead, you can stay in gear and keep moving, just using the accelerator pedal. It can be less work than an automatic, where you have to alternate between gas and brake. Also, if you do press on the clutch, anticipating that you might have to stop, but do not actually stop, you can just release the clutch while the car is still rolling. This is quicker and easier than a start from a full stop; you don't even think about it. 216.31.219.19 (talk) 21:44, 29 July 2013 (UTC)
thread_title:  Lots of clutch use in heavy traffic? Not true! 

message: I haven't read the whole article but the bits that I have seem to have a heavy American bias such as standards, car references (e.g. Buick, Pontiac, Caddilac are not common cars outside the U.S.) and road references, etc. 
Perhaps some sections could be rewritten for a more worldwide view (by addiition not subtitution)?Angry Mustelid (talk) 23:07, 10 May 2014 (UTC)

message: Manual transmissions are lubricated with gear oil (or engine oil in some vehicles) which must be changed periodically in some vehicles, although not as frequently as the fluid in an automatic transmission. 
While I concur with this, understand manufacturers now consider most automatic transmissions a "sealed unit" that doesn't require fluid changes, while the same model with a manual, if it exists, still has the recommendation of 30K mi fluid changes.  57.135.233.22 (talk) 19:21, 8 May 2024 (UTC)
