Cvt gearbox issues

[Steven knight]

Hi Guys , I'm having intermittent issues with my gearbox on a 2013 forester XT . It seems to be either hunting or missing a gear change at very low revs , then I hear a squeel sound.  I  contacted my local dealership who if I'm honest were no help , didn't recommend any action, advised against a service and left me none the wiser. All my local auto gearbox specialist seem to run a mile when trying to book it in . Has anyone else experience similar and if so how did you rectify ? Any advice would be greatly appreciated.  

Kind regards Steve
