How to adjust shifter to align with indicator

[TotalChevy1]

I just recently pulled my steering column and painted it and replace some of the parts . Went to install last night and noticed that my shifter is off. If the indicator says it's in park, it's actually in reverse. If it says reverse, it's in nuteral...you get the point. What's the best way to fix it. I was thinking I could loosen the tranny linkage and reset the shifter to the correct positon on the indicator and then secure the linkage.... or is there a easier way or do I have bigger problems.

Thanks
