Swapped to T400....now tach won't work

Just finished a T56 to T400 swap and now my factory tach won't work. Is there a sensor that needs to be hooked up somehow from the old tranny? The tranny has the yank speedo calibrater and it seems to be working.

The tach is not tied to the tranny. It's off the motor, I'd double check your tach wire out of the PCM first.
