Technician A says that the torque available at the output shaft is greater in 2nd gear than when the transmission/transaxle is in 3rd gear at the same engine speed. Technician B says that the output shaft is rotating faster when the transmission/transaxle is in 2nd gear compared to 3rd gear when the engine is at the same speed. Which technician is correct? A) Technician A only B) Technician B only C) Both Technicians A and B D) Neither Technician A nor B - ANSWER A) Technician A only The driving gear has 15 teeth and the driven gear has 29 teeth. Technician A says that the output gear will be going faster than the input gear. Technician B says the ratio is 3.86:1. Which technician is correct? A) Technician A only B) Technician B only C) Both Technicians A and B D) Neither Technician A nor B - ANSWER D) Neither Technician A nor B Which part is splined to the clutch disc? A) Main shaft B) Countershaft (lay shaft) C) Cluster shaft D) Main gear - ANSWER Two technicians are discussing how torque is increased inside a manual transmission/transaxle. Technician A says that the gear ratio in 1st gear between the main shaft and the countershaft should be multiplied by the ratio of the corresponding countershaft gear and output shaft gear. Technician B says that the two ratios should be added together. Which technician is correct? A) Technician A only B) Technician B only C) Both Technic
