Good Morning Gentlemen,

I have a 2001 740iL. A transmission line broke on the freeway and thereafter my trans started acting strange. I purchased the master rebuild kit and I rebuilt my transmission this weekend. I replaced all clutches steels, o rings and seals. Rebuilt the Valve body also. After mounting the trans I connected the gear linkage. I put the trans in neutral and bolted on the Drive-shaft. Next I wanted to screw in torque converter bolts. In order to do so I tried to turn the drive-shaft to align the torque converter bolts and found that when I turn the drive-shaft the torque converter doesn't turn. I then put it into park to see if that would engage and it wont. In park the wheels spin freely. So turning the drive-shaft (or wheels) while car is in the air will not engage torque converter and putting it in park will not engage parking mechanism. I shifted through all the gears and still nothing. I dropped the pan to ensure that the inside linkage is correct and it looks fine. outside linkage looks fine also. Any assistance would be appreciated.

It could be that you did not push the torque converter enough into the bell housing. When installing a transmission, the torque converter has to be installed into the trans and then the trans is mated with the engine.
