Hello Everyone! Major newbie here, but happy to be a part of this community! My issue...is with the shifter. I have a 2010 GT Mustang with the V8 315 HP with a 5 speed manual transmission. The problem is MYSTERIOUS so I'm hoping one of you can provide some insight. Shifting under normal driving conditions is absolutely fine. The problem shows up when I start pushing the car hard, getting the RPM's close to red line and possibly doing some hard braking. After a few minutes of this the car becomes very difficult to shift and sometimes after I've come to a stop at a light and go to put the car in 1st, the shifter will completely lock me out (I can't put the knob into 1st). In these cases, I have to turn the car off, restart ignition and usually I can shift again. I'll go so far as to say that the car definitely becomes harder to shift when running the RPM's high. One time, I took it to the drag strip for a few fun runs and it would fight me when I shifted into 3rd. Any thoughts are much appreciated! -Dan
