During my search, I learned to recognize the signs that my TCM might be failing. I began to pay attention to unusual behaviors such as slipping gears, delayed shifts, and even warning lights on my dashboard. If I noticed any of these symptoms, I knew it was time to consider a replacement. It became clear that addressing these issues early could save me from more significant repairs down the line.
