T56 sudden sloppy/loose shifting

[ADY]

I have only 1,000 miles on a new t56 that I purchased from Hurst Drivelines I installed on my '68 Camaro. I don't drive it hard and most miles have been at freeway speeds. Last week I noticed the shifter was starting to become really loose and doesn't take much effort to pull it out of gear. It engages the same and doesn't slip out of gear, just feels like its heading that way. Anyone have any idea what could have happened to it?

thanks for your help!
