I have a 03 Sunfire that rolled 101,000 miles and when I go to put it into gear (automatic) it feels like the gears slam into place. I gave it a transmission fluid and filter change and it felt good for a couple of weeks then again it started slamming the gears again, when i put it into reverse or drive. When I am on the highway the tranny feels great. It only happens when it is in town (stop and go driving). Any suggestions what to look for or to do. Could it be a sensor? Please help.

 

WOW!!!!! This sight is great if you want someone to listen to you and not respond. Anyhow I found 2 problems with the car. The first one is the slamming of the gears was caused by 2 broken motor mounts (upper and lower) I found some good mounts on http://www.carcustoms.net. Here are a couple of pics in case you are trying to picuture the mounts (upper) http://www.carcustoms.net/images/rk-02031010.jpg , and (Lower) http://www.carcustoms.net/images/cc-0002.jpg The second problem I had was a check engine light that came on. I took it to an autozone and they put the OBDII connection and read the code. P01113 displayed and indicated that my IAS intake airflow sensor was reading different temps than the other sensors were reading. This item I picked up at autozone for $10. My engine light is off. I hope my work helps others out since I could not wait for them. Have fun
