The first step is to find out what type of transmission your car has. There are two main types of transmissions: manual and automatic. Manual transmissions have gears that you shift manually, while automatic transmissions shift gears automatically.
Step 2: Find your car's model and year.
Once you know what type of transmission your car has, you need to find out its model and year. You can find this information on your car's registration or title.
Step 3: Find your car's transmission code.
The next step is to find your car's transmission code. This is a unique code that identifies your car's transmission. You can find this code on the transmission case or in your car's owner's manual.
Step 4: Look up your car's transmission ratios.
Once you have your car's transmission code, you can look up its transmission ratios. These ratios are available in your car's owner's manual or online.
Step 5: Calculate the final drive ratio.
The final drive ratio is the ratio of the number of teeth on the ring gear to the number of teeth on the pinion gear. This ratio can be found in your car's owner's manual or online.
Step 6: Calculate the overall gear ratio.
The overall gear ratio is the product of the transmission ratios and the final drive ratio. This ratio tells you how many times the engine has to turn to rotate the wheels one time.
Here is an example of how to find the gearbox ratios for a car:
* Car model and year: 2016 Honda Civic
* Transmission type: Manual
* Transmission code: M6F
* Transmission ratios:
* 1st gear: 3.231:1
* 2nd gear: 1.789:1
* 3rd gear: 1.281:1
* 4th gear: 0.971:1
* 5th gear: 0.781:1
* 6th gear: 0.639:1
* Final drive ratio: 4.111:1
* Overall gear ratios:
* 1st gear: 13.335:1
* 2nd gear: 7.367:1
* 3rd gear: 5.312:1
* 4th gear: 3.996:1
* 5th gear: 3.234:1
* 6th gear: 2.629:1
These ratios tell us that, in 1st gear, the engine has to turn 13.335 times to rotate the wheels one time. In 2nd gear, the engine has to turn 7.367 times to rotate the wheels one time. And so on.
