When I went to drive it does not shift

Make sure the filter is in good and has anew o-ring/gasket and the old o-ring/gasket was removed. Filter may not be in all the way if it was working good prior to you doing work. Make sure you used correct fluid as well. Fluid automatic transmission fluid plus 4 or plus 4 type 9602. If okay I have seen the transmission governor regulator and sensor go out. Here is the location in the diagrams below. Check out the diagrams (Below). Please let us know what you find.
