Talisman Automatic Transmission Issue

That sounds frustrating! I had a similar issue with my Talisman. The symptoms you describe – engine not starting, check engine light, and the gearbox acting up – are very familiar. In my case, it was a problem with the gear linkage, and the car thought it wasn't in park or neutral, even when it was. Have you tried fiddling with the gear selector to see if it makes any difference? It might be worth a try before diving into more complex troubleshooting.

I have attempted to manipulate the gear selector, but it hasn't helped. Could you elaborate on the specifics of the issue you encountered with your Talisman? Any additional details would be appreciated.

It was a while ago, but the issue was intermittent at first. Sometimes it would start fine, other times it would act exactly as you described. Eventually, it got worse, and I was stranded a couple of times. My local mechanic diagnosed it as a faulty control unit affecting the park/neutral safety switch. Basically, the car didn't know it was in park, so it wouldn't allow the engine to start. Given your symptoms and the error code, I'd strongly suggest taking it to a reputable workshop for a proper diagnosis. It sounds like you might be facing a similar issue, and it's better to get it sorted before it causes further damage. Based on my experience, expect a hefty repair bill, maybe around 1000€, if it's indeed the control unit.

I appreciate you sharing your experience; it has been most insightful. Considering the complexities involved, I shall heed your advice and consult a qualified mechanic to conduct a thorough assessment of the vehicle. Thank you again for your assistance.
