Hi i have a 2005 honda rancher at 400 and since the cold winter my 4-wheeler has been acting up with reverse. It started to flash "---" when i put it in reverse and will almost stall out if i keep pressing on the gas, but when it got warmed up it would stop. It now does this all the time, so basically i have no reverse. If i put it into reverse and quickly hit the gas i can get about 5 to 10 feet before it starts messing up. Also my 4-wheeler has the ESP or AUTO shifting and if i am using the ESP and shifting with the pushbuttons it seems fine but in full on automatic it flashes "---" and wont let me shift out of the gear it was in. Any suggestions as to what might be wrong would be greatly appreciated and a huge help.
A little side note, last winter i took it in to honda for service and they said i needed a new clutch and they put one in. My main compliant at that time was that the 4-wheeler would not downshift in full automatic until it came to a stop first.

 

Did you ever figure out the problem. Im currently having the EXACT same issue

 

How many times it flashes, long and short, is the code which (in theory) tells you what is wrong. This doesn't always work as you can get false codes, but is a good place to start.
