I would stay away from opening the gearbox. There are alot of special tools on this gearbox but more important putting this gearbox back together takes careful setup of the bearings. If done wrong it will eat itself in a few thousand miles. And the cost to repair when it needs all the bearings is terrible. I have taken 100's of these apart I have never seen a bent shift fork or a misaligned shift rod. I have seen worn shift forks. There are 4 shift rods in the gearbox 1 for R, 1 for 5th 1 for 1st and 2nd and 1 of 3rd and 4th. They have a lower and upper hole the ride in so they can't get out of position. Worn reverse synchro or damaged a damaged operating sleave or even damaged reverse gear are common. Lot's of guys just replace the entire reverse gear set-up when they open the box.
What I would do to determine if it is a linkage issue or a gearbox issue is disconnect the shift linkage at the gearbox itself. This will leave you with the shift shaft sticking out of the gearbox about 3 inches. I would place the shifter in neutral before doing this. When it is centered in and out will give you 3rd and 4th. Moving it one way and moving it in and out will give you 1st and 2nd. So when you move it the other way you will have R and 5th but they are not exactly on the same in and out. It is a little hard to explain. You move it sideways a little and it will go either in or out then center it again and move it a little more sideways and it will go the other way either in or out. To do this movement use either a round punch or screwdriver that can go through the hole were the bolt held the linkage to the shift shaft. If this is too much rambling let me know and I will try to explain it better. Good Luck, Bernie
