Domain: technology (Engineering Design and Analysis)
Problem: I am assembling a simple transmission model, and the figure above shows my target structure. During the gear installation process, I reversed the mounting positions of the No. 2 and No. 3 gray gears (marked with numbers in the figure). The size ratio of the gears is designed based on the first-generation Suzuki Alto. Please tell me what the actual corresponding gear positions are when the original shift lever is moved to 1st, 2nd, 3rd, 4th and R gears in this installation mode.
Answer: 1, 3, 2, 4, R
