no gaskets IIRC,but you might want to get the 1 1/4" manual shift selector seal along with the TPV shaft seal.

those will be ez to change with the VB down and on the bench.

couple washers and a bolt/nut pulls the seal into the case, and TPV seal is done on the VB at the work bench.

make/get a mumbly peg for your detent ball for when it goes back together. holds ball in place while you put rooster comb back on.

good luck
