Equus Transmission Parking Defect

Evening. My 2011 Hyundai Equus with a gasoline engine is giving me grief. It's got 191739 km on the clock, and the automatic transmission seems to have developed a parking position defect. The engine won't start, the check engine light is on, and the gearbox is slipping, resulting in unclean shifts. I scanned it, and there's an error stored in the memory. I suspect it's a defective control unit causing all this. Anyone experienced similar?

The gearbox is slipping, leading to unclean shifts, and an error is stored in the memory. The suspected cause is a defective transmission control unit, though a faulty gear shifter could also be responsible. It is recommended to visit a qualified workshop for a definitive diagnosis and repair.

I also own an Equus. Your symptoms sound familiar. I experienced something similar with my transmission. Does it feel like the gear linkage is completely off, like the shifter isn't properly engaging the parking position?

That's a good way to put it. Yes, the gear linkage feels completely disconnected. Does that confirm it was the control unit?

While I cannot confirm definitively that it's the control unit, my issue did turn out to be a defective transmission control unit. Given the symptoms and the error code you mentioned, it's highly probable. I would advise visiting a qualified workshop to confirm the diagnosis, as a faulty gear shifter could cause some issues as well.

Thanks for the insight. I appreciate you sharing your experience. It definitely gives me a clearer direction to go in. I'll get it checked out by a workshop. They've quoted around 1000€ for the repair, which seems reasonable given the likely cause.
