I think i can make from Markku's words, that the quality is good, but the operator friendlyness is poor(er) than other synchro transmissions.
However your 8045 is not synchronised, so for you it would be an improvement anyhow.
Yes, the hydrostatic steering, from Danfoss or Orsta, will mean a huge improvement over the old power assisted, that used to leak like a basket.
