Gear damage?

Hello Reader & Helper, I have a problem with my recently acquired V70, year 2000. I am now driven 4Tkm and am very happy with the car…. except for a little something that might be a bigger problem. I have problems switching into the first gear when I step into the clutch. The first gear only goes in with a lot of resistance. If I switch to the third or second gear before, then the first one goes in better, but not 100% light. The problem gets over. If I brake the car to a standstill and let the clutch kick all the time. The first gear then goes wonderfully easily in. But as soon as I release the clutch and then step again, I have the problem as described first. If I stand on a slight slope and the first gear does not go in and let the car roll only a few cm forward, then the first gear also goes wonderfully lightly in. I was at 2 Volvo dealers. The first wanted me the Kuppl The car has only 94Tkm on the clock and is, I suppose, driven well in front of me. Can someone possibly help me further? Thanks, Mario
