My 16 GT350 intermittently pops out of 1st gear when letting out the clutch, it did it twice on the way home from the dealer when I first got it. I figured it was just me. It has continued but there is no consistency to it. I just installed the new MGW shifter, went to take it for a test drive, slipped it into 1st and started to let the clutch out and out it popped, anyone else having this issue?
