727 small block shifting issues

Step 3

Drop the trans pan and see what's sitting in the bottom of it, and if it has a magnet see what is stuck to that too.

Good time to adjust the bands to the proper inch pounds then back off turns adjustment > both bands.

Check the filter, could be plugged. Good time for a new filter and fluid change if things don't look totally shot.

never opened a transmission up but i'm not opposed to buying a book and tearing into it.
