Ford 150 OD Transmission install in 31 Roadster
 

I am looking to install Ford RTS 150 4 speed trans with a 41% OD.

Car is a 31 Deluxe Roadster with Snyder 5.5 head, enlarged intakes, new motor, B grind cam, FSI Zipper distributor and 4:11 rear end.

I would appreciate it if the people that make the complete 150 kits PM me with your kit info, or reply to this post so others could have the same information.

I have read everything I can from the Barn, Hamb, Mitchell, Volvo, etc.

Several members of my club, The Hangtown As in Placerville California have those transmissions in their Model As. They are very happy with them. I think you'll need a AA bell housing to make the switch.

Are the AA bell housings difficult to find? I have heard that they are needed for this application and I hear of so many out there that I wonder where one finds the AA bell housing or is someone reproducing them? I may want to do as Old31 did. I have a 411 gear set and all the bearings. Might be a fun project for winter days when it's raining out here in sunny CA.

old31 - the 41% OD will work good for you with the 4.11 rear. Unfortunately, you will still have nearly the same final drive ratios you have now in 1st, 2nd and 3rd........A better setup is the 26% OD transmission with a 3.78 rear.

I have the 27% or with 3.78 rear. Works great.

Still confused about this. Are you saying that there is too much of a change from 3rd to OD?

I was hoping to leave the rear end alone.

Also, does it matter what year AA bell housing that you use?

I don't think that BH will work for a Ford 150. It says for a 5 speed.

Re: Ford 150 OD Transmission install in 31 Roadster
 

No, I don't think there's too big a jump from 3rd to OD. Your overall radio in third is 4.11 and in OD with the 41% transmission, the ratio would be 2.91. With the 27% trans the ratios are 3.78/2.96. All I was saying is I think you would like the drivability of the roadster better with the 3.78. I have the 3.78 with the 27% OD trans and a stout motor in my 30 pickup and I'm thinking of going to a 3.54 rear because you can almost drive the truck by starting off in 2nd gear.(my overall ratio in 1st is 12.28)

"I don't think that BH will work for a Ford 150. It says for a 5 speed."


It will work fine. The BH doesn't care what is behind it, 4 speed or 5 speed. Fabrications (or Kit)must be done with either one.

Needs to be a 4-speed bell housing used in 1930-31 AA.

Good Morning...You might also consider the Mitchell Overdrive. I have had one for 12 years with a 3.78 rear end and it has been wonderful and has not given me any problems...also it is designed specifically for the Model 'A' Ford. :) Ernie

Re: Ford 150 OD Transmission install in 31 Roadster
 

There are a couple of guys that fabricate a bolt-in kit using the Ford Tremec RTS transmission. That's the best way to go, as all the fabrication and machining is done for you.

MAG and old 31. The bell housing refered to above (listed on ebay) is a 1930 or 31 AA bell housing. It was -in the AA - coupled to a four speed Model A transmission. It is the same one we use to convert the F150 to Model A engines.

Old31. you will need the 30-31 four speed bell housing from a Model AA truck. BTW I think I have one left from my kit building days.

I have spoken with Mitchell and with owners of Mitchell. My problem is I just don't like the idea of having 2 levers or a pull cable.

I have spoken with Tim Sheridan, Valley Machine, and Gary Bernard. I ruled out Gary and Valley because they remove the torque tube.

Do you know of anyone else?

What would be wrong with this option? https://www.macsautoparts.com/ford_m...n-shifter.html

eagle, that is an original 3 speed transmission converted to synchonizers. There is no overdrive in that transmission. I think the OP wants an overdrive.
