99 diesel
 

I have a 99 3500 five speed that i cant get into gear if the truck is running. I can shut it off and it will go into any gear. But if it is running and sitting still u may get lucky and it will go every once in a while. If it is rolling and you get the rpms just right you can shift it that way as well.
We put a slave cylinder in it last night and going to do the clutch master cylinder today but niether one of those have bleeder valves on them and was wondering if there was a trick to bleeding the system or if i was in the right direction on getting it fixed
