Hello, hopefully someone here can help me out.

i own a 1936 Oldsmobile and would like to add a modern transmission like a t-5 transmission.

Has anyone here ever done a modification like this or could point me to the right direction?

Or does anyone have a bell housing hanging around? i'd like the measurements from the back where the trans bolts up.

Yhanks in advance

 

I would give Rossracing a call, might be able to help or at least point you in the right direction.http://rossracingengines.com/c/11/ol...early-catalog/

 

Here's another supplier that provides adapters for the Olds 394.

The home page mentions that custom adapters can be made as well. Hopefully you can find something that works.

 

Have you looked into a Rover Transmission that should be a direct bolt up. That being said I am no expert on the 213 engine and I don't remember anyone ever using the first generation Old's transmission on a 213. Check with Joe P or Jensen Racing they both play with that engine and would know.... Tedd

 

Tedd, it's a 1936 213 c.i. L head inline 6 engine, not the 215 used in the first F-85 & Cutlass.

 

My mistake, I was thinking aluminum V8, what a difference two ci's make.For some reason my thoughts were street rodding today.... Tedd

 

I would put money on it that you need a custom made adapter. What bell housing pattern did they even have?

 

My thoughts are about the pilot bearing/bushing that will be needed to make this work. I would think that the new trans will have a larger diameter input shaft and things could get tricky.

 

thanks

i had checked with them but they don't make anything for a 213

 

Bummer!

 

This swap would be WAY more trouble than it is worth.
For one thing . the old "torquey" flat head six just doesn't need five speeds .
The swap would be a total nightmare . As no one makes (or has ever made) an adapter for this .
My advice would be to stick with the original trans . Parts for it can be had . Especially through the internet . Use Google .

 

These folks might have the parts for your original transmission:

I bought a rebuild kit from them when I rebuilt my Slim Jim Rotohydramatic in my 64 98. They have good service and a lot of hard to find parts you won't get from B&M or TCI.

 

hmm ok thanks, i was just trying to get better highway gears

 

If what you want is better "highway" gears then it is the rear end that you need to change , not the transmission .
In 1936 most roads were still dirt or gravel . and speeds seldom exceeded 50 MPH on those . The best highways were the two lane concrete US highways where 65 MPH was "just flying ".
Car makers geared their cars accordingly . According to my research , the 36 Olds had a 4.56 rear gear .
By the 1950's the roads had much improved , and the speeds were higher.
So the gearing for stick shift cars was something like 3.70 or 3.90 . Automatic cars ran even taller at 3.23 or 3.08 .
The 1936 Olds had a rear end that was only used in 1935-36 . The ring gear was rivited to the diff case. There was a very limited selection of gear ratios , and all of them were in the "granny gear "range .
In 1937 Olds (and Pontiac ) went to a newer design axle that they stayed with as late as 1956 .
It may be possible to swap a complete rear end from a 50's Olds (or Pontiac) into your car. Try to find one that is close to the same width .3.55 to 3.70 is probably the best ratio .
You will have to find a welder by the name of McGuyver , to move the spring perches and build a new driveshaft . But it should all be do-able .
I did a similar thing with a 1937 Pontiac coupe (4.37 rear). I used a rear end center chunk out of a 54 Hydra-Matic (3.23 rear). Made for much easier cruising .

 

I think he is looking for more ratios and no doubt overdrive with 4.56 gears. I'm sure oen can be made up with a steel plate and some skill.
