What is the purpose of a selector fork?
The gear selector forks slide along the layshaft of a manual transmission, as the clutch is held down, and select the gears, which are controlled by the stick-shift, by the driver.
What moves the shift fork?
When the driver moves the shifter to select a gear, the shift rail moves a shift fork that's attached to a synchronizer. Each synchronizer is capable of changing two-speed gears. Most five-speed manual transmissions have three shift rails.
Do automatic transmissions have forks?
The most obvious differences include a manual transmission having both a clutch pedal and a gearshift or a stick shift, while automatic transmissions have neither. A manual transmission includes a clutch, gear selector fork, collars, and several gears and shafts.

What is shifting without the clutch called?
Float shifting or floating gears, also called "slip shifting", "dead sticking" or "bang shifting", is the process of changing gears, in typically a non-synchronous transmission, without depressing the clutch.
How long does a clutch last on a automatic?
Your automatic clutch will likely last anywhere from 30,000 to 100,000+ miles, depending on how you drive and how closely you stick to the recommended maintenance schedules.
How do automatics know when to shift?
An automatic transmission uses sensors to determine when it should shift gears, and changes them using internal oil pressure.
What is a gear shifter called?
A gear stick (rarely spelled gearstick), gear lever (both UK English), gearshift or shifter (both U.S. English), more formally known as a transmission lever, is a metal lever attached to the transmission of an automobile.
What is 1st gear used for?
1 – First gear. To be used when you require more power but less speed and to prevent the transmission from shifting to a higher gear. These gears may be used when going up or down hills and on road conditions like slush, loose gravel, snow, sand or ice, where you need more power but less speed.
Are higher gears faster?
In general, you'll want to keep this rule of thumb in mind: the lower the gear, the more power you have available. The higher the gear, the faster your engine runs! With both manual and automatic transmissions, you'll generally move from lower to higher gears as you accelerate.
What is a shift rail?
Manual transmission shift rails connect the shift lever to the shift fork. When the driver moves the shifter to select a gear, the shift rail moves a shift fork that's attached to a synchronizer. Each synchronizer is capable of changing two-speed gears. Most five-speed manual transmissions have three shift rails.
What is synchronizer hub purpose?
Synchronizer hubs are powder metal parts often used in vehicles for manual and dual clutch transmissions. The synchronizer hub, which synchronizes mechanical connections to shift gears, needs to have high strength and durability.
What is the input shaft?
The input shaft is connected to the engine via the clutch, such that when the clutch is engaged, power goes straight from the engine to the input shaft of the transmission, and the crankshaft and input shaft rotate at the same speed.
What is a gear linkage?
The gearbox linkage transfers movement of the gear stick to the gearbox, allowing gear engagement. We stock high-quality gearboxes and linkages for all cars. In a sense, the gearbox is the intermediary between engine and wheels. Its job is to optimise the engine's rotational speed to achieve the desired road speed.
What is a shift fork?
The shift forks move the internals of the transmission to allow you to shift. The house the sychros along with the shift collar. They can be damaged by a bad driver or driving while you are putting pressure on the shifter. "no-lift" shifting will damage them.
How do shift forks work?
Your shift forks look like a circle with part of the circle missing sticking out of a shaft. Google could prolly help you with an image if you like. The shift forks move the internals of the transmission to allow you to shift. The house the sychros along with the shift collar. They can be damaged by a bad driver or driving while you are putting pressure on the shifter. "no-lift" shifting will damage them. The damage could be they are slipping on the shift rail or the keyway could be broken that holds the two together.
How does a manual transmission work?
A manual transmission works by moving "slider" collars across blocker rings which lock different gears to different shafts. The shift forks are normally a "U" shaped piece of steel that engage the slider gears and push them into the positions desired by the driver to create the intended gear. The normal position for each slider is free wheeling, or neutral. When a gear is desired, first the driver moves the lever to a range position, such as 1&2, or 3&4 and then by moving the shift lever forward or rearward the driver causes the chosen fork to push the slider so that it locks the intended gear to the shaft. Over time, the fork wears both from use, and occasionally from a drivers habit of continually leaning their hand on the shift lever. Thats why it's common to see a particular transmission lose certian gears. Many transmissions lose second, or third gear before they lose any other. While they are seperate shift forks, they are the most two common gears to be changed under load or decel. That means as much as frequency of shifting, the drivers tend to never let go of the shift lever during changing those two gears, and that causes wear until evenually one of the forks get so thin that it does not properlly engage it's slider, and the slider "jumps" out of gear. In extreme cases, the fork can indeed break. Now if it breaks and the slider is engaged, your transmission could end up stuck in what ever gear it was in. Or normally, you simply end up with some gears functional, and others that you simply cannot get to engage.
Can shift forks go bad?
Shift forks are made of pretty tough stuff. It's not impossible that one might be bad, but from your description of the problem, it's far more likely the problem is with the shift cables. They have plastic parts and are far more likely to go bad.

What happens if a fork breaks?
I know that if a fork breaks the shifter will go into position where the gear would normally be but it won't acually click into gear cause the hub is only being pushed on one side. If it goes in it's most likely not the fork.
