How do you find transmission ratio?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
How do you make a close ratio transmission?
One way to create a close-ratio transmission is to install more gears into the transmission without altering the lowest and highest gear ratios. In this manner, some six-speed transmissions available in consumer vehicles are labelled as “close-ratio”. Again, the defining issue is the overall spacing of gears between 1st and in this case 6th gear.
What is the gear ratio of a manual transmission?
When we talk about the manual transmission the gear ratio of the first gear i.e. largest gear of the output shaft and smallest gear of the lay shaft, Gives high torque and the gear ratio of the top gear gives high speed to the final output shaft of the vehicle.
How to calculate the close ratio of gears?
Mathematically, this closeness can be represented by the cumulative average spacing between, or geometric average of, gears. For the above series transmission, each successive gear’s ratio is on average 75% of that of the preceding gear (e.g. (0.82 / 2.64) 1/4 = 0.747).
How does power go from the main shaft to the transmission?
This is done by shifting the fork through the gear lever which moves the synchronizers to engage the selected speed gear to the main shaft. Power travels along the counter gear until it reaches this selected speed gear. It then passes through this gear back to main shaft and out of the transmission to the drive line.

How can I tell if my transmission is in the right gear?
Third are date codes and VIN numbers that help confirm that the above case and gears belong together. Tooth counts on the input shaft will help confirm a certain gear ratio, but you may not have access to this information if the transmission is still in the car or an unwilling vendor at a swap meet won’t remove the cover.
What makes a Hill Climb transmission a close ratio transmission?
Thus, the Hill Climb transmission’s gears are “closer” in numerical ratio to the preceding gear than that of the standard or Nuerburgring transmission, making it a close-ratio transmission. There is no specific figure that is used to denote whether the steps between gears constitute a normal or close-ratio transmission.
