      It just played the video for me John. Perhaps your browser is the obstacle?

        I tried different browsers. I also tried being logged into Facebook or not logged in. I get the message.

          Understood.

          The video is a 2 minute clip of a mechanic with a gutted cruise -o- matic/ ford -o- matic/ FMX showing how the wrong length rod was preventing the detent from fully engaging in park.

          A random fact I learned a few years back when working on a lot of old Ford transmissions from the 50's-60's is that there is something like a half dozen or so different ford o matic/ cruise o matic/ FMX case lengths.

            I had the same problem John did and the same message.

              Of all the reasons for slipping out of park, this is not the first one I'd go after.

                    I am not able to view the link either. My 60' T-bird has the same issue (it is currently in the shop getting a whole bunch of mechanical issues sorted). I spoke to the shop owner about replacing the detent plate - which I learned about in this forum. He spoke to a friend who was a former president of the T-bird association and owns a 60 squarebird (sorry - can't remember the gentlemen's name - maybe he is on here). This individual advised that even with the detent plates replaced, the cars still like to jump from P to Reverse. Ugh. His recommendation was to put the car in Neutral with the parking brake on prior to starting the car, and to use that method instead of running the car in "park." I dunno. I certainly received the message that the car shop was disinclined to take the job because they felt that it would not be satisfactorily resolved. Once I get the car back, I intend to try the suggested method and see if that is satisfactory - and to always watch out for obstacles behind!

                      Curing the problem can involve more than replacing the detent plate. Much was covered on this forum. If only I could find it?

                        As Carl mentioned there are multiple issues that cause sloppiness in the shifter; the detent plate, the shift lever, the shift collar and the gear selector lever at the end of the steering column. One of the ways to keep the shift lever in Park is to over adjust the manual linkage in the engine compartment. This will force the lever further up into the Park position and help it from slipping into Reverse. The only down side is that you most likely will lose the ability to use the L position which I never use anyway. This along with a new shift lever really helps if you don't want to go through the trouble of replacing the detent plate although I still recommend doing it.

                          Carl, this subject has been covered many times in different posts on here. Here is a link that discusses a lot of it, including the long commentary regarding the Shift Tube Selector Lever at the bottom of the drive shaft often being the major part causing this problem, a long with the worn detent plate, the tip of that shift lever, and won components inside that round collar.

                          Here is the Technical Tip referenced above that Frank La Penna (from Down Under) wrote for us 10 years ago and is in the TRL

                            There are also a number of articles in the Technical Resources Library that pertain to replacing the detent plate, shift lever, collar and shift selector lever.

                              The breadth and depth of the knowledge base here is impressive! Just learned to use D1 to start driving! Up til now, (the few times I've driven it), I have used D2! Good to know! After I get the car back from the shop, I'll have to assess what to do about the slippage. I have to admit that my repair bills have been quite a bit higher than I anticipated, and my coffers are running a little on the dry side!
