Hello everyone, I'm currently repairing a ZW310-6 device. The problem is that when moving forward in gear 2, the gearbox makes a strange noise and jerks. I checked on the MPDR and found that gear 2 always has control current flowing downwards. When moving forward, shift control is in gear 1 but the voltage is still controlling gear 2, and when shifting control is in gear 2 but the voltage is controlling gear 1. I don't have the standard documentation to confirm this, but I think these parameters are abnormal. Please help, thank you.
