There is an easier way with out removing the pan, disconnect the cable from the engine linkage first, that will give enough free play in the transmission. Remove the control cable from the transmission by pressing on the locking tap and at the same time rotating the cable housing CCW. Now you can pull the cable out of the case, with a needle nose pliers hold the TV rod, slide the cable loop off. Reverse the procedure to reinstall.

Since you removed the pan, the cable rod is connected to a lever on the valve body which pushes the throttle valve plunger; adjust the cable until the lever barely touches the plunger. Now you can fine tune the shifts. The Bowden cable ONLY controls shift timing; a tight cable = late shifts, a loose cable = early shifts.
