Gearbox Problem! Snow Flake And S Plus Service On The Dashboard

[satriani7007]

hi like in the topic,my car for some reason has this snow flake and S together with service info and i was only able to drive on D3.i stop the car turn of engine for about 10 minutes and everything back to normal apart that when hard acceleration car changing gear to 4th and stay on it without changing to 5th etc.on normal slow driving gears change with no problems at all.

So my question is what is it also is it something what should i be panicking ?

my gearbox os BVA AM6C!

I did check google and some stuff what i read was that need to get new  hydraulic block !!!!!!which i think will cost fortune !

some people suggest checking first computer but i din't have lexia or any friends around with it...so if any one live close to Greenhithe it would be great ;)other wise i will need to go to dealer which i'm wonder how much they will charge just for diagnostic?

 

btw my  car has full service history from main dealer and 73k on clock
