Hey i got an 05 fx4 with 12,400 miles. when it shifts from 1st to second gear it will slam really hard or like a grandma driving a 5speed and then the rpms rise and fall then it takes off. what is the redline suppose to be, mine is shifting at 5000 to 5200 some days and other times its 4800. all i have is a roush exhaust. i saw some pink fluid in my driveway, but i have been checking the tranny fluid everday and its at the same level.

 

12k you are still under warranty right? back to the dealer as soon as possible.
