Looking for some help on this one. Got a 2015 329E track loader, left trac will lock up when moving ahead. Eventually it will quit and operate just fine. Does not do it in reverse, works fine. When its doing this, there is a low voltage to selinoids. When working fine, voltage appears to be proper. Seems to only do it when machine has been sitting and cooled down. Once you play with it a bit, machine will run fine. We have checked all the ecm/ecu connections, looking for moisture. 3200 hrs on machine. Not sure if its shuttle valves, possibly. Martin deere says it physical, not sending a code. Any help would be greatful.
