I just inquired at my dealer about a "coast valve". I bought it for $95, installed it and machine is now a dream to drive. It actually coasts to a stop and is easily shifted with no load on the transmission. The price seams a bit steep, but I was really annoyed with the condition. By the way, the install was simple. To get at the cap, which is just ahead of the hyd resevoir, I disconnected the cylinder at the lift box and swung it backward. The cap to remove is a 10mm allen head screw.
