What did this tranny come from, and would it be an easy replacement for a New Process 4 Speed Granny. I have a 1970 F100 Long bed with 302 it originally had a light 3speed column shift (someone swapped in the granny gear). Presently I have fixed yoke and two piece shaft. I would like to go back to column shift ( I rebuilt the column months ago with that idea), I can't bring myself to take out the granny for a plain 3sp, but I will go through some trouble to do it for a T85 overdrive if it is something that will work.
I dont want to sell my soul to the machine shop making parts. Old guy has had it under his bench for 20 years (was going to put o/d behind an auto but never got any further) He say the man he got it from took it from an early 60's ( has date code of 6/19/63 on it some where) I have not seen it yet. I just asked him to get me all the numbers he could find on it.
I could have sworn there was an article on this subject but I can't find it now.
He has just the tranny no bell housing.
Thanks for any help in advance
Thanks, I had thought of the solenoid issue but I am still undecided (wife wants the column thingy back). The thing that really concerns me is the input shaft length, I thought I read somewhere that car / truck bellhousings had a different depth. I don't want to have to come up with another 3 speed to steal parts from.

Re: Identify T85C-1A / B11-1P
the T85 uses a solenoid on the transmission. and if it is bad or goes bad. the cost is upwards of 2-300.00 to get it rebuilt or buy a new one.
my opinion is that i would keep the np435 in there. but that is just an opinion.
as far as the bellhousing it should bolt right up to yours.

I don't know much if anything about that over drive transmission but I once knew a guy that had one in a 71 F100 390/3.25 rear end. He would average 18 mpg in that truck running with traffic. That always surprised me as I would think lugging a 390 like that would not help. I tried to find one before I did my swap to a C-6 and could not so went to the auto.
