The only solution is quite a laborous job.
Clean the whole mechanism from sticky lubricant and lubricate with thin oil (e.g. sewing machine oil)
You did not mention the exact type so I have to guess about the friction material of the clutches. Clean it and work it up a bit with sandpaper; take care that it stays free from lubricant. That is somewhat critical because the shifting part must be lubricated
