Hi all not sure if this has been posted before but I've searched and cannot find the issue. My 156 Selespeed started changing gears by itself. When I set off in 1st it jumps to 4th then 3rd and then sometimes the indicator will show R and beeps but I'm still driving forward. I took it to a local alfa independent garage who said it was the speed sensor. Had that changed amongst other bits that needed doing. Had a full week of trouble free driving and now it's back. This morning I put it in first just put foot slightly on accelerator and it jumped to 3rd and the back 2nd. If I try selecting the gears whilst stationary it will only go up to 2nd. I've just spent a fortune and I know the car was worth less but if I could just get this problem sorted I'll be happy. Thanks for looking at this post.
