Venue Automatic Transmission Problems

Greetings. I encountered comparable symptoms on my previous vehicle, a 2018 Opel Insignia. The observed manifestations included erratic shifting patterns, illumination of the transmission warning indicator, and instances where the transmission failed to execute gear changes as anticipated. Subsequent diagnostic procedures revealed that the vehicle’s control module was reporting undervoltage, which directly affected the solenoids responsible for gear selection within the automatic transmission system.

That's interesting! So, with your Opel, was it just a low voltage issue causing all the transmission problems? Did you notice any other electrical weirdness, or was it all focused on the transmission? I'm trying to figure out if it's something simple like a battery or alternator problem, or if there's a deeper electrical gremlin at play here.

Affirmative, in the case of the Opel Insignia, the undervoltage condition was indeed the primary etiological factor contributing to the observed transmission malfunctions. Although no other ancillary electrical anomalies were concurrently detected, it is judicious to acknowledge that undervoltage can precipitate disparate and seemingly unrelated system-wide effects. In light of the symptoms exhibited by your Hyundai Venue, it is my considered recommendation that you seek a formal diagnostic evaluation by a qualified automotive technician to ascertain the underlying cause and formulate an appropriate remediation strategy.

Took the Venue to the workshop, and you were spot on. It was indeed an undervoltage issue causing the transmission to go haywire. They found a faulty sensor that was draining the battery. Replaced the sensor, and after a transmission oil change now everything runs smoothly again. Cost me 240€, but at least it's fixed. Thanks for the advice!
