In the upper left corner of Figure 1 is the transmission parameter column, select the transmission type in the type, enter the number of gears in the gear, and then enter the gear ratio corresponding to each gear in the ratio.

For the parameters in the lower left corner, please see Figure 2.

The first final drive shaft refers to the transmission ratio of the front wheel differential, that is, the front differential ratio. This parameter is only required for front-wheel drive vehicles or four-wheel drive vehicles, otherwise the default value is 1.00.
In some front-wheel drive vehicles and four-wheel drive vehicles, there may be two front differentials, one for gears 1 to 4, and one for gears 5 and 6, so you may need to enter the values of two final drive shafts. (For example Toyota Avenue 6-speed manual 2.2D, Volkswagen Golf Mk5 2.0 GT TDI)
Regarding the second "transfer rate", generally only four-wheel drive and full-wheel drive vehicles will be used. In order to deal with some extreme road conditions (mud, gravel, snow, etc.), another gear will be added between the transmission output shaft and the drive shaft (usually two gears, high and low), that is, a transfer case is installed Make the vehicle output the maximum torque. The input of "transfer rate" is the transmission ratio of the transfer case (there are two transmission ratios of low gear and high gear).
The third item is the transmission ratio of the rear wheel differential, which is generally required for rear-drive/full-drive vehicles. If it is a front-wheel drive vehicle and does not have a rear wheel differential, the default value is 1.00.

The last part is the pulley measurement/speed ratio. As shown in Figure 3, the input is all the pulley diameters (Diameter) or speed ratios (Speed) that have a transmission relationship with the crankshaft pulley.
For example, if the diameter is selected for the type , the crankshaft pulley diameter is measured to be 150mm, and the AC (air conditioning)/compressor pulley is measured to be 75mm. As shown in Figure 4, enter these dimensions in the corresponding boxes. (Generally, the diameter of these pulleys may not be found in the technical manual, and technicians need to manually measure them.)
Figure 4
If the type selected speed ratio , it is necessary to input gear ratio between each pulley and the crank pulley. The frequency of the crankshaft pulley is E1, assuming that the frequency of the AC air conditioner/compressor pulley is 1.75 times that of the crankshaft pulley, which is E1.75. Then fill in "1" in the crankshaft pulley of Figure 5, and fill in "1.75" in the AC air conditioner/compressor pulley. By analogy, fill in as many times the frequency of other pulleys as the crankshaft pulley. (Usually, the transmission ratio between each pulley and the crankshaft pulley is not in the technical manual, and the technician needs to measure it by himself.)
