let me start out by saying my saleen is a piece of junk that has given me nothing but problems since day one, and as of last night at 18800 miles, when im in high rpms and shift into 3rd, all i get is a grind then it goes into gear, driving and shifting at low rpm there is no problem, only when excellerating decently... would you take it in for warranty with aftermarket gears or take them out and replace the stock gears and still hope the dealership covers the transmission under warranty...any suggestions or anyone with the same problem feel free to reply
