350 trans problem

I went out for a ride in the coupe today and now i have a shifting problem. It is a 350 trans and it shifts 1and 2 great but it will not shift to 3 stays in 2. Replaced the governor and no change. Any ideas it is driving me crazy. It also has vacuum to the modulator and no fluid in the vacuum line.

 

It sounds like your direct clutch drum is bad, a common problem with 350's

 

Not the information I wanted to here but Thank you for the help. I will drop the trans tomorrow.

 

Try disconnecting the detent cable. Maybe its hung up. Certainly worth a try.
