Hello, guys.

I owned a used 2004 Nissian Maxima. Like others, I also got several transmission problems with my car.

First is when I put it in "D", sometimes the car would slam on the gear. It is like the gear shifts hard. That problem is much more serious when I drive the car for a while, like 50 minutes. By the way, it was much more serious before. It was a harsh slam on the gear. Now I replaced the transmission fluid as it was pretty dirty. It was much better. But it still exists sometimes.

Second is transmission slipping. Once when I was waiting for the red light, I accelerated the car. The rpm went up, but the car did not move. I accelerated again. It moved. Another time was I was keeping accelerating the car on the car, it slowed down in 1 second and returned to acceleration again. This problem also happens not very often.

Anyone has the same problem with me? Thanks for looking and help.
