55 Thunderbird Gears in 39 Trans

[Mart]

Not many responses, but I for one am following with interest.

Keep up the good work on this interesting job.

I think the 55 t bird trans is the same as 55 mercury is the same thing.
I would guess it may work with open drive. Those gears were very tuff.
If it was easy it would be done today.
I would like to see it work.

Reading this post made me think abour what i did to my 46 way back, 1&r were missing teeth, and I couldn't find any gears, i found a later model trans missing the input shaft and the gears looked much the same ---except the cluster had 1 less tooth ---i put it together anyway, it didn't make noise, and survived side steeping the clutch downshifts many times ---the countershaft bearings were all loose needles, not the caged ones the original trans had, I remember doing something to the thrust washers too ---I never found out what the trans was from, but the case was much different than the 46, and looked different than the 49-50 flathead trans pictures

You mean like this one we did on a '35? 2.95 Camaro gear set! 4.03 is for the 'uninformed'! DD

I'll see if Lawrie says something, Im sure he modifies for later gears to fit.
