Transmission Problems
 

I have a 2001 3.8 mustang. When i shift into 5th gear at high RPM and high speed (3500, over 75mph) It grinds a bit, anyone else have that problem? and the warranty is still good on my car, i think, i did add dual exhaust, Think that voids it? Any help would be appreciated, thank you.

Just Ford Transmissions for you. I put a short throw shifter on mine and it cuts that down alot.

Thanks, its reasurring to know that i am not going to be spending the next 1000 dollars i make for a transmission rebuild
