4L60E Leak

Have a 93 4L60E tranny that has been loosing fluid. Parked vehicle about 3 wks ago and filled tranny. Woke up this moring and found fluid leaking from center hole in driveshaft yoke. No leaks at rear tranny seal. Is there an O-ring in the shaft or yoke and what would cause it to leak out of the center of yoke? Thanks, PCox.

many of these trans have a metal sleeve with O-ring on the output shaft that seal on the yoke. Pull the tail housing off to see.
