I drive a 2016 Cadillac XTS. At 102k miles, it started to rumble like you’re going over railroad tracks when changing gears (you could feel it coming from the pedal). At first mechanics could not diagnose cuz no engine light was on. It continued and I took it back to the Cadillac dealer. They drove it home and said the torque converter needed to be replaced. $3900 quote!! Since they were so unsure I took it to a trusted mechanic locally who I had worked with when I owned lesser cars and worked with him for 10+ years.
He said the torque converter was fine but the transmission fluid needed to be changed. So he did that for $400. It made it better but didn’t resolve entirely. I’d still feel that locking sensation when at lower gears (about 20-40 mph it could catch). I did more research. Everything pointed to torque converter and that this could help as lubrication from manufacturer can go bad. The manufacturer of this product says this will work in roughly 20 miles. If it does it’s a fluid/lube issue. If not, it’s a mechanical. Well 100 miles later, my car is running GREAT. In fact, my dad sold it to me for a 2019 XTS. He drove it after to test it out and said its running better than his newer model. Now will it last forever? Maybe not. But I can afford $10 every few thousand miles for this product to avoid a $3900 bill!! I hope this helps
