15. Now we move to the fork arm shifter pivot base. This part can be a bit tricky. It really pays to have a pick tool set handy. There is a spring and ball bearing inside the little cylinder. There is an access hole in the top where you can see the spring coils. You need the very fine tipped pick tool here, as you need to grab the coil behind the last coil you see through the access hole. Otherwise, the spring will not compress enough to allow the ball to retract and let the shifter pivot base loose. You’ll need to hold the spring back as you remove the fork arm from it’s socket in the case. Take extra care, because if that spring releases, you could be in for a long search for the ball bearing!!! Once you have the fork arm removed, using your magnetic tool, remove the ball and spring and set them aside on your workbench.
16. Your transmission will now look like this with the fork arm removed.
17. Now we can remove the secondary shaft. Lift and tilt the differential, then tilt and pull up on the secondary shaft to remove it. Pay close attention to any washers or rings and keep them in the proper order.
18. Now remove the differential by simply lifting it out.
19. It has been discussed and shown, that a small portion of the internal case must be ground down in order for the LSD to fit and spin freely. This info comes from the 4cyl BP Protege and Escort GT transmissions, as well as the MX3 GS but as you can see in the first 2 pics, this Probe GT transmission already has that spot ground down from the factory, so this mod was not needed. The 3rd pic shows where the BP 4cyl transmissions have been ground for the LSD.
