Question

Shanae Culmer · Accepted Answer

Final Answer : A, Explanation :  Technician A is correct because in twin and triple countershaft transmissions, the mainshaft and countershafts are indeed mounted parallel to each other. Technician B is incorrect because torque from the input shaft is typically routed first to the countershafts, which then drive the mainshaft, not the other way around.
