I posted my problem with my Falcon's 4-speed a while ago here: https://mustangforums.com/m_1451207/tm.htm

Well I had the same problem again and did the quick fix by yanking on the clutch cables to get them loose. Anyway, you guys suggested that I rebuilt the linkage. I was having trouble googling the steps for this or if there is some sort of kit available. How would I go about doing this? And what parts would I need? For the most part the system works fine, but its just that once in a blue moon it gets stuck. Would cleaning up down there and/or WD40 take care of it? I was thinking of trying that first before a rebuild. Thanks
