I have a 2001 v92C Deluxe I have had since new with around 25,000 miles. When warm and sitting a a stop light I start to accelerate. It pops out of 1st gear and can be put back in without any problem. Also sometimes I will be sitting at a stop light and I hear a faint click. It has jumped out of first. Can anyone give me an idea what is going on and what is the fix.
