If the sound goes away when the clutch is depressed then the sound is coming from the rotating internals of the gearbox, depressing the clutch will allow them to come to a stop (bear in mind that it's a constant-mesh box, so if the clutch is up then the internals spin even in neutral when the car is stationary) The best diagnosis is to drain the gearbox ...

After checking the coil, make sure the grounds are good. Sometimes the ground wiring breaks inside and its not noticeable with a visual inspection. A bad ground will create idle issues. This is a common occurrence with Toyotas.

My issue like that was a simple mass air flow sensor

As a somewhat paranoid motorcyclist, I'm a huge fan of remaining in first, with the clutch disengaged until at least one vehicle has fully stopped behind me, after that if the remaining stop time is long (frequently it isn't) I may switch to neutral. Until that vehicle has completely stopped, you're at risk of being rear ended by someone failing to stop in ...

Your question is incredibly board because it can be broken into 5 distinct aspects; planetary gear sets operation, clutch and band operation, torque converter operation, control system operation and the power flow through the transmission. Further complicating the answer is that there are hundreds of different types, kinds and transmission manufacturers. For ...

1st and Reverse often don't have syncro clutches on the gears. A lack of these makes it difficult to select the gears while the car is moving. However they shouldn't make a difference when the car is stationary. There again, you probably never select the other gears while the car is stationary. Additional by @Paulster2 - If the friction disk is spinning ...

Well - most older cars that didn't have a TCU used manifold vacuum to determine shifts. When one of the vacuum hoses broke or fell off, the transmission wouldn't shift properly. But this won't be realistic for your bicycle - you'll have to write some software and figure out an algorithm that will work - using some speed and torque sensors. It's new ...

Some cars have There was 50's era MG that used them. I couple of model years of Toyota MR2. The E46 BMW M3. Some reasons manufacturers that have used them and dropped them is user complaints. It shifts hard. The consumer isn't used to the idea of going down through all the gears just to get to 1st. It's louder and sounds unnerving In BMW's case ...

How is a 0-100 run done? The fewest number of gears possible will be used, because that's the fastest way to get to a given speed. Engines typically put out their highest power in a certain band of RPMs, so you will accelerate as much as you can in first gear (to the red-line, or to a certain RPM where you know the power starts to decrease), then shift to ...

I haven't owned a bike that hasn't been awkward to get into neutral while stationary at some point, my Bandit was the worst for it. I found that it's usually easier to find neutral while the bike is still moving so I got into the habit of engaging neutral as I come to a stop rather than after I've stopped.

It could be your... Synchronizer rings Modern transmissions use synchronizer rings to make manual shifting possible without the need for double declutching. Each gear has its own synchronizer ring. These rings are subject to wear. If they are in bad condition gear synchronization doesn't work well and you have trouble putting in a certain gear.

Firstly, check for any signs of fluid leak (if you've not done so already) - has the level in the reservoir changed? (fluid leaks aren't always obvious, the level changing is the best indication) How old is the truck, and when was the fluid last changed? It might be worth changing it anyway... The fact that you can change the behaviour by pumping it ...

In most sport-oriented (and heavy towing) vehicles, the point of an extra transmission gear is to keep the engine operating between it's torque peak and HP peak. Thus, most models of vehicles that are base models will have a 5 speed manual (or 3 speed auto), while the sportier or heavy duty versions will have more gears to chose from. Many 6 speed ...

If you have 20 gears, you would have to "shorten" each gear (ratio) to "match" the gear it came from and the gear it is going in. So you go through "smaller gears" faster (more gears).

The generic term "gear ratios" refers to the ratio of the number of teeth on two meshed gears. Two gears that are meshed (teeth engaged with each other) must have the same sized teeth or they would not mesh. So, given the same sized teeth on both gears the term refers to the ratio of the number of teeth on each gear. For example, if the first gear has 50 ...

Here's a link to an article that describes what you're looking for in detail. http://auto.howstuffworks.com/transmission.htm What the gearbox does is allow the engine to run at the RPM range that it is most happy, while allowing your wheels to run at the speed which you desire. It does that through a collection of gears who's ratio determines how fast the ...

Gearbox designers should avoid integer ratios like the plague. For mechanical reasons. Integer ratios will accelerate wear and tear because it increases the frequency with which tooth A on the driver gear will meet tooth B on the driven gear. This frequency is known as the hunting tooth frequency, which I've explained in more detail here. Regarding 1:1 ...

tl;dr: different gear ratios are a feature, not a bug. Some cars use more gears for acceleration, some use them for better gas mileage. You can't do both. At 3300-3500 RPMs, shouldn't the WRX be able to achieve better gas mileage by keeping the same 5-speed gear ratios, while adding an additional gear to lower RPMs to 2800-3000? You've exposed the ...

Most vehicles will only have a single overdrive, where the second to the last gear will be a 1:1 ratio (or something near it). The notable thing here is the Tremec 6-speed transmissions (used in the Camaro, Viper, Corvette, Mustang, and others) which have the double overdrive. The main purpose of more gears is to allow the vehicle to stay in the torque/hp ...

You may want to check out your clutch. When do you feel pressure on the clutch pedal? If anything you may have a small leak in your clutch lines or the master cylinder. Mine did this too, where it was hard to get it into 1st gear. Its because my clutch wasn't disengaging all the way. So I filled it up on clutch fluid (brake fluid) and bleed the clutch and it ...

The bearing you are looking for are still available in the United States. Do a google search for "1983 Yamaha OEM parts" You will see various Yamaha websites. Goto one and chase your bike with the make/model/year and this will be the result, the ability to purchase the bearings. All of the transmission bearings for the bike are still available for ...
