Have you adjusted it to neutral? That's how I adjust my JVX (Winters) shifter.
I have tried that yes, I can either adjust it to hit every gear perfectly but not park, or it can hit park and everything else is wrong.
Mine works about 50% in Park. It works 100% in neutral so that's the backup plan. I'm not certain but it seems to me there are different length switches. You might also have a bad switch. I'd check the year the trans was built and get a switch for that year and compare to what you have. O'Reily and Autozone carry them. Some shifters have neutral switches built into them too. I don't use them as I like the tranny switch, it seems more durable and accurate!
I switched linkage and neutral switch with the other trans just to rule that out, no difference. I think I am going to pull the VB and compare it to another I have. I have three transmissions here and 4 cheetah VBs, i'll find something that works.
