Hi, I had no problem with the K1, I didn't fix it. Solenoid valves were checked, oil and filter changed. As for the K1 - information from the company that deals with the repair of automatic transmissions: "The gearbox enters the emergency mode, because the output RPM sensor detects the differences in RPM beyond the limit. The reason for this is the slipping clutch K1 (burnt friction plates / mechanical damage to the K1 basket). This fault occurs for a reason. For the correct operation of the clutches - the discs control board, solenoid valves, pressure regulators correspond to friction elements. Due to the expensive parts and the difficulty of disassembling / assembling the crate, repairing such crates is uneconomic. "
