Trajet torque converter issue

I have a Hyundai Trajet too, and while the specifics are different, what you're describing sounds vaguely familiar. I had a similar issue a while back, also auto transmission, albeit not exactly the same symptoms. Was the error code specifically pointing to the torque converter, or was it more generic transmission trouble?

The error code was pretty specific, mentioning the torque converter lock-up clutch. I'm starting to think it might be a defective automatic transmission converter. What kind of error code did you get and how similar was your issue? I am just trying to get an idea of what I'm up against here.

Ah, torque converter lock-up clutch specific, that clarifies things. Mine was less precise, but led down a similar path. Given the grinding and slipping, and the error code pointing directly at the torque converter, it's highly suggestive of a converter issue. Honestly, with those symptoms, I'd strongly advise taking it to a reputable workshop for a thorough diagnostic. Continuing to drive it in that condition could lead to further damage to the transmission.

Thanks for the insight. I appreciate the advice. I took it to the workshop, and you were right – the automatic transmission converter was defective, just like the error code said. The repair cost me 2120€, but at least it's sorted now.
