I got on the freeway tonight on the way home from my gf's house and i put the cruise on and when i did the rpm's went up to 4k and came back down to normal at 70 and i just kept idling up and back down. It was really weird and it wouldn't stop doing that. Then when i got on the surface road i decided to get on it a bit and i opened it up and it seemed like i had added like 50 horses. Not that it's a bad thing but my trans felt like it a 5sp would when you shift from 4th to 2nd at 50mph. even though i was only doing 40. It's got me really confused. Btw. I've been having trans problems about it hesitating to shift sometimes. Any ideas?
