okay sometimes when i shift from 3rd to 4th at HIGH rpms the shifter gets stuck trying to shift into 4th. I have to double clutch it to get it in and it only happens when my rpms is around 4rpms or higher. now every other gear has no problems at high rpms shifts but 3 to 4 has this problem. i went to the dealer to check it out and they said that it was my clutch (even though i didn't think so). they replaced it and a couple days later it happened again. does anyone have this problem? what should i do? is this normal? what should i tell the dealer? kinda scared to go in there again 'cuz they'll probably say they see nothing wrong with the car.
