Its not a T86. Its either a T85 or T89. Probably a T89. Either one is a stronger box than the T86.

thanks.. i was hoping for it to be a T-89 cause i know that's one of the stronger boxes.. there is a spot on it where it looks like an ID tag used to be so i'm a little in the dark.. the tailshaft unit just has the usual R-10 over-drive stamps on it so no help there.. either way i love the trans i just need to buy a couple parts for it and want to make sure i'm getting the right one's..

So does three spped "overdrive" mean it is a 4-speed manual trans?  Or is this a 2 speed trans with Overdrive for a total of 3 speeds?

I'm getting curious becuase the 56 customline I'm about to pick up has a 3-on the tree and I'm wondering what tranny that will be.  I know nothing about trannys from back then...a whole new world for me!

Looks exactly like the BW 259 (except for the two additional rust colored lug bosses) that came on the '55 Bird.



Nate;



3 speed overdrive: Though technically a "6 speed", in normal use only a 5 speed (lower OD axle ratio would require very high revs before minimum OD/governor engagement speed achieved).

Warner used a R10 and R11 tail section, the R11 being a little heavier. But the overdrive unit in both of them is pretty bullet proof. It is the front box that usually fails if they are abused. The T86 had a weaker input gear, cluster gear and sliding gear, but they are all good transmissions.



6ft6, The front box is very similar to a regular 3 speed transmission. The overdrive unit is a planetary gear that is capable of direct or .70 overdrive. There is a governor that does not allow the unit to shift into overdrive until 28 mph road speed has been achieved. You can have 6 forward gears if you use direct and overdrive in each of the 3 forward gears. This is easily achieved by bypassing the governor with a toggle switch. Overdrive really needs 3.89 for 4.11 rears to be practical. I have been driving overdrive for over 45 years and wouldn't own a Ford without one. There are a lot of good articles that have been written about Borg Warner T85,T86 T89 that can be found on the internet.

this has a R10 unit on it.. i just think it's weird that i can't find a stamping on it.. the T-10 i used to have had "T-10" stamped on it plain as day.. there is a spot on the top of the main gear box that looks like it may have had some type of ID plate on it at one time but it's gone now

Hi, I am new here and I just purchased a 3 speed manual with Borg Warner R10 F 1A overdrive, who looks similar. The seller says it comes from a 55 T-bird, but I am not sure, so I need the help of the experts here.
