I have been having a little trouble when I shift from park to drive in my 90 accord. I have to give a good hard pull to get into drive. When I shift back into park from drive I have the same trouble. Sometimes it won't even go back into park. I have to move back and forth between park and drive untill it finally locks in. Shifting between drive and reverse and neutral and all the other gears works fine. Could this be just a simple linkage adjustment? thanks

 

yes, sounds like a linkage problem. You adjust it on the transmission side.
