I have found from the club that this would have been a 1939 transmission build. Now my question is-???!!! What is the function of the 7206 Housing guide pin shown in the lower small drawing of the shifter in Figure 15, page 6 of Ford 3 Speed Transmissions Typical of 1936 to 48. Wait! On page 2 Figure 3: 40-7222 Shifter Housing and also Figure 5 68-7222 Shifter Housing there is a bulge in the casting on the right (passenger) side of the central tower and apparently a little dome as if a rivet type peening of pin at the rear of that bulge. Seems to be all connected until. Look at Figure8 and 9 on the facing page 68-7230, 91A-7230 the engagement slot for the pin seems to lean to the left or driver's side and has other protuberances on it's other side. I see no way for the 7210 gear shift lever to engage the second and high fork in addition , though in Figure 49 Shifter housing and forks there is an impeded view of a squarish tab on second and high fork directly opposite of the low-reverse tab ahead of the notch. Both tabs are directly over the hole in the center. The 1941-48 Ford Book by the Club Fig. 4-21 1942-48 Side Shifting Transmission is no help. I put the pin on the opposite side in my views of a model and left the puzzle underneath unsolved. There is no question that the side shift gears would work in the central shift case as I did this swap from parts I took out of my 1948 in 1957 and kept in a wood box until I needed them in 1964, now however with better data, should I have tried to locate a 1939 shifter?

I have those items and referred to specific pages and items in my post. Unfortunately, Van Pelt never has any text on the "7206 Housing guide pin" that appears in his favorite drawing. I speculate it is like a rail the "hand and arm" of the intermediate and high fork guides along. As I studied it I first said it is like a Chinese laundry list, very long and detailed but inscrutable, then I supposed maybe like a strap hanging commuter who moves to the door as the train approaches the station holding to the rail of the upper baggage bin and avoiding the cord that stops the train. Thanks for posting the links. I have the physical book here. For gear tooth count and building task plan it looks great. Apparantly, the pin I have identified never wears like the Chinese laundry list or it is so lightly contacted in use it has no reoperation expectation. As for the difficulty I have with where I think it is, photographs are sometimes mirror images and sometimes the shifter has a reverse H pattern for a RHD as in England, Japan or Australia. Has anyone ever seen this part in a tear down? How do they differ with the years? I have had a spur gear low-high version, a steel synchro version and the mentioned brass blocking ring version of gears and gearbox but never had a need to know about the "Housing guide pin" but now 55 years later is it still infinite life? I found this link which clearly shows the bulge on the left or driver side of the transmission tho ugh I cannot see the head and tail of the pin. It's in three parts with the 3rd actually for a 1939 which also clearly has the cylindrical rather than truncated long cone of the shifter housing tower. https://www.35pickup.com/Transmission.html This message was edited by therunwaybehind on 7-13-19 @ 2:27 PM
