The power light is coming on and off for few seconds every time i start the engine.Any ideas what is it? thanks

Almost certainly means the auto box ECU has a stored error code and/or is failing a sensor on startup - you need to run an auto box diagnostic.

I'll have to see Ryan for this because i don't know too much about the car... thanks a lot

If it just comes on for 2 secs or so when you first put the ignition on and then goes off dont worry, this is normal, to show that its working.

mine did this when i removed the abs fuse once, instead of the engine check light comming on. weird.
