Rare optional 3 speed overdrive trans

Found a lady selling off her deceased husbands stash of 1950's and 1960's pickup parts here in Alabama and I am going to drive over and acquire all of it in the morning. Among the interesting parts I spotted was a seldom seen original 3 speed overdrive transmission and bellhousing. the two were separated so I'll have to wait and see if they truly go together but assume so. Anyway, until I load it all up I won't know what all I am really buying, but I wanted to tell all of you about the 3 speed O.D. because that is a very highly sought after changeover trans with many enthusiasts in the 60-66 crowd.

Text me at 256 486 1988 with 60-66 parts wanted and I will check the stash and see if its among these items I am getting tomorrow or something maybe I already have

Re: Rare optional 3 speed overdrive trans

Do you by chance have this bracket? It is the bracket that is held on by the solenoid bolt that holds the overdrive cable sheath. Thanks

Re: Rare optional 3 speed overdrive trans

What’s the ratio of the top gear? Will it fit a 66 K14 Burb?

You also need to check and see if it is a Tri-Five 3 speed OD transmission. They are different. They will bolt up to the later bell housings but if I remember correctly first gear is not synchronized in them. Also, a different bolt pattern on the side cover. Someone correct me if I'm wrong.....

All of the 4 bolt side cover overdrive transmissions are non-syncro 1st. The 7 bolt side cover overdrive transmissions are fully-syncro'd

Re: Rare optional 3 speed overdrive trans

Got the trans and it is a non-synchonized 1st gear type trans with a 56 or 57 date code so will work on 60-66 but not date coded to 60-66. $250 for the trans itself - no other OD related parts were present - inquire if interested
