a) Take off the cover between the rear seats which exposes the shift coupler. Pull up the shifter boot, particularly so you can see the lower part of the shifter lever where it bends from "angled back" to more vertical.
b) Loosen the retaining bolt which pinches the shift rod on to the spline on the shift coupler. Let it be very loose.
c) WITH THE TRANSMISSION IN NEUTRAL, rotate the shift coupler clockwise when viewed towards the front of the car. You should be able to feel the coupler rub against the various shift stops as you rotate it back and forth. Rotate it to the furthest clockwise position, as seen when you are facing forward. Don't pretend you are Tarzan and turn it with huge force....lightly is all that is necessary..
d) Keep your hand on it and hold it there. Don't let it wiggle, if it does, turn it back to the furthest clockwise position.
e) Move the shift lever so that the more vertical part of the lever is vertical (ie 90 degrees to the level...sticking straight up so to speak). Move it so that it lightly touches the side of the shifter housing which is on the 1 st/2 ndgear side.....closest to the driver. Again, gently.
f) They should now be properly aligned.....lever closest to the driver with bottom part vertical, coupler clockwise in the neutral plane.
g) Carefully tighten the pinch bolt. Make sure it is quite tight.
h) Check things out. You must be able to engage reverse clash free (give the gear a little bit of time to stop after you stomp on the clutch), shifting should get to all the gears easily when driving.....things don't work as smoothly when stopped and lastly, there must be a little bit of rotational play when 5 thgear is selected. This is checked by shifting into 5 th, and feeling whether you can wiggle the shift coupler with your hand. It should just click back and forth slightly...not much, but clearly discernable play.
i) Assuming all is well, put all the covers back. If it is not well....my fervent suggestion is that you START OVER at b. ....I have never had any luck fiddling with the linkage.
