VW Eos Trans Grinding Points to Failed Torque Converter

Had nearly identical symptoms with a VW Scirocco 2009 gasoline. The lock-up clutch inside the torque converter was failing, causing transmission slippage and harsh gear changes. The converter failure progressed rapidly after the first warning signs appeared. A proper diagnosis revealed metal particles in the transmission fluid, indicating internal wear in the torque converter. The auto transmission required a complete overhaul since the contaminated fluid had already affected other components. The repair involved: Removing transmission, Installing new torque converter, Replacing solenoids, Flushing transmission lines, Installing new filter and fluid, Reprogramming transmission control module This was a major repair job requiring specialized transmission tools and expertise. The engine surge and erratic shifting completely resolved after the work. Without prompt attention, these symptoms typically lead to total transmission failure. Would strongly recommend finding a shop specializing in VW automatic transmissions rather than a general mechanic. The diagnostic equipment and experience with these specific transmission designs makes a significant difference in repair quality.

Thanks for the detailed write-up of your Scirocco transmission repair. Your clutch problem symptoms match what Im experiencing with my Eos. Just had it looked at and the torque converter is definitely the culprit. The transmission repair shop confirmed the diagnosis but Im still debating whether to proceed. Would you remember roughly how much the total repair cost in your case? Also curious if youve had any transmission issues since getting it fixed? My mechanic mentioned potential problems with other components and Id like to know what to expect long term.

Really glad I can help with cost info based on my Scirocco repair experience. The total price came to 2120€ for fixing the defective automatic transmission torque converter, which included all parts and labor. This resolved the engine surge and transmission slipping issues completely. Since having the lock-up clutch repaired over two years ago, the transmission has performed flawlessly, no more converter failure symptoms or any other transmission-related problems. The investment was worth it considering the alternative of total transmission failure. My recommendation would be to proceed with the repair while the damage is still contained. Waiting too long often leads to more extensive transmission repair costs when metal particles from a failing converter contaminate the entire system. The grinding and slipping you describe are classic signs that need immediate attention. Getting it fixed by a transmission specialist now will likely save money compared to waiting for a complete system failure. Plus, you regain the peace of mind of having a properly functioning transmission.

Thanks for the feedback. I bit the bullet and had the transmission repair done last week. The torque converter replacement ended up costing 2350€ but the shop found additional wear in the valve body that needed addressing. The automatic transmission is shifting perfectly now, no more grinding or slipping between gears. The mechanic showed me the old converter parts and there was significant internal damage that would have eventually caused total transmission failure. The shop I used specializes in VW auto transmissions and had the right diagnostic equipment. They completed everything in 3 days and even provided a 12-month warranty on parts and labor. The investment was higher than expected but worth it to avoid further damage to the gearbox. For anyone facing similar converter fault symptoms, I recommend getting it checked immediately. The grinding noises and erratic shifting were clear warning signs that the torque converter was failing. Waiting would have only led to more extensive repairs.
