Gearbox oil needs changing.
The gears in the speedometer are stripped. If the odometer is working then you have input.
check the u-joints in the drive shaft first
have you checked the oil level in the transmission ? I'm betting the answer is no
The gears inside the odometer broke due to heat and age. You can buy the gears and replace them yourself. Or you can take your car to a place were they work on odometers.

Shifting Gears - DJ Z-Trip album - was created in 2005.
Your bike gears may not be shifting smoothly due to issues such as cable tension, derailleur alignment, or worn-out components. It is recommended to have a professional bike mechanic inspect and adjust your gears to ensure smooth shifting.
To adjust Shimano gears on a mountain bike, start by shifting to the smallest chainring and cog. Then, use the barrel adjuster to fine-tune the shifting. If the chain is not shifting smoothly, adjust the cable tension by turning the barrel adjuster. Test the gears by shifting through all the gears to ensure smooth operation. If needed, repeat the process until the gears shift smoothly.
