The gear box of my 1916 is working fine except for going out of grip when climbing hills in 2nd gears. To avoid that I need to hold the gear shifter from changing position and a possible break down thereafter.
Would the gearboxes to 490 passenger cars be the same size/construction from late 1915 to 1922? I would think so, but do not know for sure. Would it be possible to make the part(s) in trouble instead of changing the whole unit? Do I have to remove the box anyway to mend it?

Thanks for any help. I have some pictures of a spare one which may be used, and the one in my car to show, to send in a PM.

Many of the 4 cylinder gearbox gears will fit into your case. Up to 1923 , all should fit into your 1916 case . The top selector mechanism is different.
1924 onwards the clutch Gear (input gear) is different as the clutch changed from the cone clutch to the disc clutch and pressure plate design.

The gears are probably easier to find in a second had gearbox than NOS / NORS gears. Failing that, the gears can be copied by a competent gear cutting firm as they are all straight cut.

Yes remove the gearbox.You will have to disassemble the gearbox and inspect all the gears for worn teeth, and then replace them or have them copied.
