Error Codes Transmission (TE32000 Alternative)
The transmission control unit has two modes with limited functionality that are activated to protect the transmission in the event of severe malfunctions:
- “Limp Home” mode, indicated by “LH” on the display. In this mode, only the 1st and 2nd gears can be used in both directions. If the malfunction occurs in a higher gear, manual downshifting to 1st or 2nd gear is required.
- “Shutdown” mode, indicated by “Sd” on the display. In this mode, the transmission remains in a permanent neutral position because there is insufficient oil pressure to engage any gear.
