today I started cleaning up the transmission of my '71 Mach I. It has a 4 speed toploader, but what I found makes me wonder what exact type it is.
Looking at some pictures that claim to show the original transmission (on the 429mustangcougarinfo website) I suspect my toploader can't be the original one. Compared to what I saw, my transmission has some kind of build in switch (for the back up lights).
So does anyone know what type of toploader this is?
around 1971 or 72 ford started putting those switches for either the backup lights or a neutral safety switch even though i would think the neutral safety safety switch should be on the clutch. you can remove the switch and get a plug from dan williams toploaders (828-524-9085) or david key toploaders or keep the switch. i had one of those cases and removed the switch and pluged the hole for my 65. btw that IS a real ford 4 speed toploader and NOT an imposter 3 speed with o.d. !
Thank you all for your help. I know have confirmed by the casting number and the tag that it is a '72 transmission for a Boss or CJ. Unfortunately, the first part of the VIN stamped into the flange is not readable. But I already know from the other information that it is not the original transmission. However, I'm not that much concerned with originallity.
