Hey guys, I looked through a bunch of past threads and although there’s a lot about 621’s on here couldn’t find exactly what I was looking for. 1997 621b loader, after I load a few loads of feed it will lose just reverse if I leave it running between loads. If I shut it off between it’s fine for the next load. Checked ohms in the 5 solenoids when this happens and all are within range. It’s only got to sit shut off for about 5 minutes then will operate again. When it’s working everything works great auto shifts in both forward and reverse. Put a new speed sensor on as well within a year. Owned for 5 years now been a good loader, just been battling this for the past few months. I have a service manual for it and have not started the electrical troubleshooting yet. Was hoping maybe someone had an idea and could point me in the right direction.
