Hello to each other. My wife drives a C4 Grand Picasso automatic (semi-automatic) 2.0 diesel with 138 hp built in 2008. For some time now she has the problem that the return gear sometimes does not work. If you switch to reverse the display gear is defective. After engine turn off and start again everything works completely normal again. Then for days nothing happens where everything works normally, then it comes before it happens several times a day. now it is so that it is very often vo It seems that it is not a mechanical problem of the gearbox but rather an electronic or even software. Before I go to the workshop now I wanted to know what experiences others have with this problem. I also had similar problems with Chrysler and Mercedes B Klasse. I wanted to install a new gearbox for several thousand euros, although only electronic components for a few years were used. Euro only had to be exchanged, or at Chrysler only the software had to be reinstalled and everything was good again. Also with Picasso I think that you certainly do not need a new transmission. thank me now in advance for your answers. p.s. otherwise it is a super car of Picasso
