Error codes transmission (transmission alternative TE32000)

Control unit transmission can generate two modes with reduced functionality to protect the transmission in case of serious malfunctions:

“Limp home”, indicated in display with “LH”.In this mode only 1-2 gear in both directions can be used. If the malfunction occurs in a higher gear then downshifting has to be performed manually to 1st gear or 2nd.
“Shutdown”, indicated in display with “Sd”. In this mode, the transmission is in permanent neutral position as there is no oil pressure to enable selection of a gear.
