63whoopie,
I was afraid you would ask that question so I found an old post on the subject and copied it.
Read it and see if it is clear enough for you to follow. I wrote it last year, so if it is confusing, I won't be suprised.
I don't know if this is the official procedure, but this is how I would do it. I would first remove the linkage from the shift arms on the transmission and make sure they "snapped" into each position..you want to make sure the detent is holding them firmly where they belong in each gear.
You want the shift arms on the tranny in neutral, you will adjust everything TOO THEM.
The shifter box on the column has two arms, one is 1st and reverse, the other 2nd and hi. The arms must be aligned to the "neutral gate". This is the motion of the cab shifter up and down..through the gate!
You attach a shifter rod from the box to the shift arm on the tranny, then attach the other arm in the same fashion. You can adjust the shifter rod that is the easiest to access so that when you sit in the cab and move the shifter up and down, you don't feel any clicks, or hitches in its git-along..smooth! This means the gate is adjusted perfectly. You need only adjust ONE arm. You are matching it to the other arm.
The shifter box and shifter in the cab are DUMB! They rely on the detents in the tranny side cover to index. Other issues that might be affecting your truck would be worn out bushings on the shift box. This would give you slop that might cause problems. I am not sure on this item, but a sagging cab might also induce problems.
If the shifter is "falling" out of gear, these procedures might help...If the transmission is "popping" out, being forced out, you have other mechanical issues...not necessarily adjustment. Good luck and keep us posted.
