What do gear synchros do

Unbelievably all of this happens in the fraction of second it takes you to shift gear, providing you with an even smoother gear change. So the next time you seamlessly slide through the ratios, take a moment to appreciate all the thought and work that went into creating the complex arrangement of cogs helping you on your way.

Most modern urban vehicles fitted with manual transmissions likely feature a synchronized gearbox also referred to as a synchro-mesh gearbox.

This device keeps the gears in mesh and rotating, or they can be locked to the shaft. It was a remarkable evolution in manual transmissions because the synchronizer did away with the need for motorists to perform double-clutching — releasing and re-engaging the clutch twice whenever changing gears — a requirement to operate a vehicle with a manual transmission unsynchronized gearbox.

It included a sliding-mesh gearbox, and the driver would need to carefully time when to shift gears to ensure the gears were rotating at the same speed, which was no easy feat. However, the unsynchronized gearbox continues to exist. You will often find them installed in transmissions for large commercial vehicles such as heavy trucks and farming machinery, as well as in motorcycles and high-calibre race cars. For two reasons: synchronized manual transmissions are more prone to breakdowns, and shifting gears on a synchro-mesh gearbox is slower than the unsynchronized version.

When transmission repairs are required, determining the cause and cure for what ails can be tricky. Just as you have other parts of your car serviced, your transmission needs maintenance to ensure a long life and avoid transmission problems.

I had the transmission on Kasun De. I had the transmission on my TL rebuilt here. From the arrangement of towing to picking up after completion of work, everything was handled professionally by Kyle. I was informed of every step during the work and there was no surprises. Time line for work performed was exactly what I was told and pick up was easy. There were no surprises with the bill.

Definitely would use these guys again if I need to. Very happy with the work. The staff took the time Stan Dunajski. By: HowStuffWorks. When you shift gears in your manual-transmission car, you move a rod that moves a fork that engages the gear. Depending which gear you're shifting to, a different fork does the job. The fork moves the collar to the desired gear, and dog teeth on the collar mesh up with holes on the gear in order to engage it.

You engage reverse gear through a separate, small idler gear. The reverse gear always turns in the opposite direction of the other forward gears. In years past, double-clutching was common in order to disengage a gear, allow the collar and next gear to reach the same speed, and then to engage the new gear.

To double-clutch shift, you pushed the clutch pedal to free the engine from the transmission. Then the collar moved into neutral.
