VW Transporter Torque Converter Failure Warning Signs

Having some experience with automatic transmission issues, I faced nearly identical symptoms on my 2020 VW Multivan last year. The lock-up clutch started acting up, causing similar transmission slipping and grinding during shifts. The converter fault turned out to be a complete torque converter failure. My workshop diagnosed it through their diagnostic system and confirmed the transmission needed major work. The repair involved: Removing the transmission, Replacing the torque converter, Flushing the transmission fluid, Updating the transmission control module Total repair cost was 2120€ and the work took about 4 days. Since the repair, the automatic transmission has worked flawlessly with no recurring issues. However, to provide more specific guidance for your situation, could you share: Current mileage, Type of transmission fluid used, When was the last transmission service, Any previous transmission repairs, Exact fault codes showing up These details would help determine if your symptoms match my experience exactly or if there might be other factors to consider.

After 53238km and no prior transmission issues, I am experiencing exactly the same torque converter symptoms you described. Thanks for sharing your repair details. The diagnostic report from last week matches your fault description. My case seems identical, though I was hoping for a less expensive fix than your 2120€ repair cost. Still, knowing the complete repair process and timeframe helps set realistic expectations. I will schedule a workshop visit this week since driving with an automatic transmission fault could lead to more severe damage. Did you use OEM parts for your torque converter replacement?

Thanks for the follow-up about your transmission situation. Yes, I insisted on OEM parts for my torque converter replacement, which was crucial for the repair's long-term success. The price difference between OEM and aftermarket parts was only about 200€, making it worth the extra cost for reliability. The workshop used genuine VW transmission fluid and followed the exact factory specifications for the automatic gearbox repair. This attention to detail likely explains why I have had zero converter fault issues since the fix 14 months ago. With your mileage being similar to when my clutch problem started, the symptoms align perfectly. One tip from my experience: have them check the transmission fluid cooler while the gearbox is out. My mechanic found minor debris there from the failing torque converter, and cleaning it prevented potential future issues. My transmission now shifts as smoothly as new, with no engine surge or grinding noises. The repair may seem expensive, but considering the complexity of modern automatic transmissions, it is a reasonable investment to prevent more costly damage.

Thanks for the detailed insights about using OEM parts. Good point about the small price difference between OEM and aftermarket torque converter components. The transmission fluid cooler check is a smart suggestion I will definitely mention to my workshop. My automatic transmission symptoms match yours exactly, so I feel more confident about proceeding with the repair. I will request OEM parts and the genuine VW transmission fluid you mentioned. The lock-up clutch issue needs addressing before it causes additional damage. I have booked the repair for next week. The 4-day timeframe works well with my schedule, and the 2120€ cost seems reasonable for such a complex automatic transmission repair. Will update once the torque converter replacement is complete.
