Question

When shifting the transmission progressively, you should:

a. Only use enough torque to get the vehicle moving and then shift into the next higher gear.
b. Shift at a higher r.p.m. while using the higher gears.
c. Shift when you reach peak horsepower.
d. a. and b. are correct.

Answer 1

The correct way to shift the transmission progressively is to use only enough torque to get the vehicle moving then shift into the next higher gear and also to shift at a higher RPM while using higher gears, making d. a. and b. are correct the right answer.

Step-by-step explanation:

When shifting the transmission progressively, the correct approach to ensure smooth acceleration and fuel efficiency is to use only enough torque to get the vehicle moving and then shift into the next higher gear as soon as it's practical (option a), as well as shifting at a higher RPM while using the higher gears, as the engine performs more efficiently within certain RPM ranges (option b). Hence, the correct answer is d. a. and b. are correct. Shifting when you reach peak horsepower (option c) is not always the most efficient method, as it can vary depending on the vehicle and driving conditions. Additionally, modern transmission technologies like 7+ speed transmissions, dual clutch transmissions (DCTs), and continuously variable transmissions (CVTs) are designed to improve fuel economy and reduce CO₂ emissions by optimizing shifting patterns and the use of gears.
