I am going to do a box service today, I've noticed that it takes ages to start,it cranks more than usual the first thing in the morning it drives from 1234 until it gets warm. When you take off it has to b slow b4 it thuds to what appears to be 3rd then 4. When you hit a light it thuds but still in 4 the pedal seems harder too brake one that is, can anyone shed some light?
