oh and when im goin up hills it the rpm's drop down from just say 3,000 down to 1,500 and when I push down more on the gas pedal it shifts down a gear and the rpm's go flying up. then when I hit the top of the hill where it goes flat, it goes back to normal other than when it ****s back into the right driving gear for that speed the rpm's fly up bout a gran then go normal.
