F MERITOR Do gears fly out while driving? - jamb

Hello everyone, friends, in this video I will tell you how the ZF Meritor gearbox should work CORRECTLY when shifting from higher to lower gears.
The client complained about the gearbox, namely, the gears were flying out while driving.
During inspection and diagnostics, it was revealed that the factory five-pin relays were NOT installed; in addition, they were not connected correctly.
