The top gasket on the transmission for my 750 leaks, so I want to replace it. Problem is, I can't get the #%*@$ shift knob off!

I've been spraying it with penetrating oil for the past 4 or 5 days and still no luck. Any advice from those who have dealt with it before? I am almost wondering if it might not be easier to disassemble it from the linkage end, but I'd rather not open that can of worms unless I need to.

There is no linkage to mess with.Remove the fenders and seat mount and take the 2 bottom bolts out on the dash.Not the 2 that go into the frame the other 2 on the side just above those.

Remove the whole shifter.Just take the 2 small bolts out.They do have nuts on the bottom.And pull the shifter out in 1 piece.

Here 1/2 of this video will help.

Not bad coming apart. Trick is to get the nuts back on the bolts inside the tower. I use a long 7/16 off set box end wrench and put tape over one side on on the sides of the wrnech to help the nuts stay in the wrench. Good luck.

There is no need to remove the shifter in order to remove the top cover of the transmission.

Disconnect the parking brake linkage (one cotter pin).

Remove the 2 screws in the side of the cowl. ....Originally these did not have nuts on the inside, so there may or not have nuts inside.

Remove the cap screws holding the cover down.

Pry the rear of the cover up, and raise it as you slide the cover toward the rear. ....The bottom of the gearshift can clear everything if you raise the cover enough.

To help in re-assembly, glue the new gasket to the top of the transmission, but take care not to cover the vent (porous brass plug) with gasket goo. ....Let the gasket goo set up, so the gasket doesn't move.

Apply a smear of grease on the top of the new gasket and re-install the transmission cover. .....The grease helps seal, but allows the cover to be removed in the future without tearing (or needing) a new gasket.
