There are a few guys here with some toploader experience that might be able to help you out. Have you tried emailing David Kee? ------------- Vince 1972 Ford GTS Sportsroof - Survivor, One Family car GTS.org Admin |

| Yes. I have this one, seems the 72 and 73 units with the seat belt switch is rather elusive. |

Hey Vince, I was talking with Peter about this, I actually don't have the specific info on the 72-73 Toploader. I know the 72-73 Torino Toploader is different. When I had mine gone through many moons ago, the guys that did mine said there was some stuff they had not seen before, they were used to pre-1970 Toploaders from mustangs. With that said, David Key Toploaders will be the defacto source on Ford Toploader info. Only headache is getting a hold of them. A couple times I have tried calling them recently trying to help another member, I could never reach anyone or get responses to emails. Hopefully the folks running that company are ok, because without them, the Top Loader fans will be in a world of hurt. Side note, the 72-74 Toploaders for Q codes had an option for a T.R.S switch on the driver's side front of the main case. 1972 Manual set Chassis Volume 1 page 16-20-01 is for the Toploader four speed. Page 16-20-04 has the exploded view of the detent rods. Peter, sent you messages on FB with the pictures from the manual. -------------  Andrew:GTS.ORG admin, '72 Q code 5 speed RestomodPondering: #99Problems |

Side note, TRS means Transmission Regulated Spark. Related to vacuum switches related to cold weather operation and advance vacuum. 1973 manual set Volume 6 Page 165 in terms: TRS "A system that controls vacuum to the distributor, preventing vacuum advance while in the immediate gears. Generally used with manual transmissions." Page 8 in the 1973 volume 6 goes into detail. Side note: mine was disconnected and never reconnected.  ------------- Andrew:GTS.ORG admin, '72 Q code 5 speed RestomodPondering: #99Problems |

Hi Guys, Thanks for the info; David Kee responded with the following:
With this info, I was able to confirm i had put the unit together correctly. But, I also took the time to modify the early exploded view to show the 72-73 detent layout. You will note, 28B, 24B, 72, and the number of detents going through the side of the case. This is updated just for the detent changes, other changes i did not make. (For instance this still shows the early shift rods). I was missing the spring 24B, which he referred to as the "lighter spring", and he provided the size of this spring as being: "It is just a utility compression spring that is 1/4" diameter x 1" long x .020 wire diameter". I hope this will help someone in the future!  ------------- Pete Jenerette 1972 Gran Torino (H-Code - 4R70W) 2022 F250 XLT 7.3 2003 Thunderbird |
I don't have a diagram but the 3 short springs that came in the kit are correct for that transmission. You should have 5 detents that have black color to them and be .459" long and one silver long detent that goes on the top of the 1-2 shift rail. There should also be 2 .418 long interlock pins. The order is one spring and detent under the reverse rail, detent on top of the reverse shift rail, interlock pin in 3-4 shift rail, detent on top of the 3-4 shift rail, interlock pin in 1-2 shift rail, long silver detent on top of the 1-2 sift rail with a lighter tension spring above it. On the side one detent and spring in each hole next to the 1-2 rail and 3-4 rail. If you have a detent that shows wear on one end you can use it where there is a spring and put the slightly worn end toward the spring.
