I've got a P27.9 EVX 1999, when started from cold it drives forward and backwards it does feel a little like the brake are on slightly though but when its warmed up it loses it drive, when trying to get ot to move then it seems to be stuck in reverse and the onlynway to stop it is to select neutral on the low/ high range lever. When cold it works again until it warms up. Any ideas for me to look at. Many thanks
