Gearbox/clutch issues MPS6

[Rtomazoni]

Hello, I am with a Volvo XC60 2012 T5 with the gearbox MPS6. But in the last months the car is more often in the maintenance then in the road. Last issue I have the car doesn’t engage rear gear, shows warning on the dash panel related to the gearbox malfunction. After several trial the car engaged the rear gear, however when I put the leaver on drive position it engage de second gear and doesn’t allow me to increase speed after 30km/h.
I have recently change the clutch and the car drove nicely for 2 days. Anyone have faced similar issues with this gearbox? What have you done to solve it?
