The $75 you paid 25 years ago was not what you got. 1st, 1stOD, 2nd, 2ndOD, 3rd, 3rdOD, 4th, & 4thOD. Thats 8! The solenoid used in the later Saganaw 3 speed OD has a longer shaft and the older GM, Stude etc solenoids will not engage the paul in the OD unit. The later Fords might work but I have never compared them. Here are some
pics the traneys are mid to late '50s GM and mid 60s Saganaw. same case as 4 speed. The long shaft solenoid with the angled cap is the only one that works in the late Saganaw. But it's just a yarn that was printed in Hot Rod in May of 70 I believe. Lots about this on the net. Beater
