Greetings,

I'm currently rebuilding my 722.4 W124 gearbox, but facing some difficulties which I can't solve it. K2 drum seems to be stucked and wont even turn when I rebolted the front pump, rear cover and 30mm flange bolt, and input shaft seems to be directly connected with output shaft. Can't even turn input shaft when in P. Already replaced all the bearings and it's still the same.

Any ideas guys?
