Have you only lost second gear? Do you still have fourth? If you still have fourth gear it is probably a bad 2/4 shift servo. Replace it with a Corvette 2/4 servo or get one of the many servo shim kits and replace the o-rings and shim the servo for higher apply pressure, which is basically what the Corvette part does by design.
If you do not have fourth then it is either a bad 2/4 band or the band retainer in the case.
