What is wrong with my car???

It all start when I stuck in a traffic jam at damansara for about an hour. At the end of it, my gear go crazy. Cannot select correct gear or gear drop or just goes free. Then come the trans prog indication. Later car cant move. (like clutch slip) After switch engine, then all back to normal.

Later in the evening go back to seremban, all ok at plus highway. Then after toll, when start moving, gear goes free again. Have to go slowly. Cannot apply power straight away.

Is it :

1. Clutch problem? (bcoz I didnt free my gear when stuck at damansara, always on drive) or

2. gear box problem? (again this year)

try to check the automatic gearbox fluid level 1st, it may be low, or there is insufficient fluid pressure before you ever think of many complicated stuff:)

also try to check the external controls for the automatic gearbox may simply need replacement or adjustment..trans speed sensor gila ka
