How do I choose the right gear ratio?
To find the ideal selection, multiply the final drive ratio by the redline speed in fourth gear (152 mph) and divide that by the top track speed (140 mph). This would yield a theoretical 3.33—which is close enough to the nearest available final drive ratio of 3.36:1.
Is 3.73 a good gear ratio?
FACT: A 3.73 axle ratio is ideal for towing heavy loads on flat terrain and will produce increased fuel economy during steady-state, long-distance highway driving.
Is 2.47 a good gear ratio?
1 to 1 or direct gear, is always the best gear for fuel mileage, quietness, cooler temperatures in the transmission, and more pulling power. However, to run in direct gear, the rear gears must be either 2.64, 2.47, 2.21 and I think there is even a higher gear than the 2.21. The average speed today is 70 miles per hour.
What should be considered when selecting rear end gear ratio?
A number of factors must be considered when selecting a rear-end gear ratio (ring & pinion set). Tire diameter, transmission choice (with or without overdrive) and desired highway cruising speed.
What should be considered when choosing a transmission?
Tire diameter, transmission choice (with or without overdrive) and desired highway cruising speed. Tire diameter is the first consideration because styling and available space within the wheel opening dictate the size of tire / wheel combination that will be chosen for the car.
Why are there 6 gears in an automatic transmission?
Normal automatics have a certain number of gears that are referred to as “speeds,” hence “6-speed automatic,” for example. The reason is that each gear is good only for a certain vehicle speed, so if you need to keep accelerating, the transmission will shift up through the gears — first 1, then 2 and so forth.
Why are there no gears in a CVT transmission?
The reason is that each gear is good only for a certain vehicle speed, so if you need to keep accelerating, the transmission will shift up through the gears — first 1, then 2 and so forth. But a continuously variable transmission technically have no gears; instead, it’s like having one magical gear that’s variable through all driving situations.
