hi i have a 2008 gt, with just about 11,000 miles. i put a Hurst competition short throw on it about 6 months ago. everything was fine until 2nd and 3rd gear started to grind every once in a while when i was racing. i asked a buddy of mine that has a hurst shifter what was wrong and he said it was probably bc of the stock trans fluid, and to change to royal purple. so i went to an advanced auto and bought trans fluid and a lucas additive. when i was buying it tho the guy told me i needed atf royal purple and i questioned him about it bc the car is not automatic and he said thats what my tranny takes and i even had him call ford to make sure. so i go home and change the fluid. when i was done i drove it around nice and slow and everything seemed great it went into gear like butter. but wen the car warmed up all the way i ripped on it alittle and when i shifted it grinded every gear i put it in =[
i freaked out and went online and foundout that i dont use royal purple atf for some reason and i ordered 9 bottles of the manual one. i then went back to the store and told them what happened and they paid for the new fluid.
my friend told me that i had to drain the fluid, fill it with the right stuff, then drive it around for about a week and then drain it and fill it up one more time to flush it out. so i did that and all was well.
but now right wen i turn my car one and go to work it will grind the first time i put it into 3rd but if i go to 4th then down to 3rd its fine , and its fine every other time after.
i dont know what it could be besides maybe there is alittle bit of the atf still in there and since its so thin it sits on the top and when i first start the car thats the first thing that gets into the gears before the rest mixes in.
please if anyone know if thats it or you know of the real reason please let me kknow it drives me crazy =[
thanks
