I have a 1999 Toyota Camry. Bought it from dealership a year and 3 months ago. I went from 150,000 to 170,000 miles on the Odometer. Overtime the car started to shift rough (automatic vehicle). I changed the transmission fluid and even added the Lucas transmission repair. It still shifts rough. Car runs well, but it just jerks hard whenever it shifts gears. What could the issue be?
And on a side note, some people said it maybe a computer part need replacing but the Check engine light isn't on and no codes show up.
