Yes, I've seen a subtle surging in engine RPMs while cruising. What was the diagnosis and resolution of your issue? Any details on error codes or the repair process?

Okay, the engine surge seals it. Sounds almost exactly like what I went through. The error code pointed straight to the torque converter. It's not a cheap fix. Get it to a good workshop ASAP. Driving it like that can cause even more damage. Likely the lock-up clutch inside the converter has given up the ghost. Better to bite the bullet now than need a whole new transmission! Hope this helps!

Sounds rough! I had something similar happen with my V70. Slipping, lights, groaning – ringing some bells. I was pulling my hair out. Any weird engine RPMs, like a surge when cruising? That lock-up clutch can cause some funky stuff. The error code will tell you more. Good luck!
