three on the tree shifting [more scale model research]
 

speaking of transmissions .... the floor shift was omnipresent until when; around 1941 or so?

but what happens if a rodder has a three speed transmission, and not the means or desire to put the lever on the floor?

for him, the journey may be the destination with no hurried anticipation of getting there.

or maybe his gal likes doing the "slide-over" and sitting next to him on those long drives. kinda hard to feel romantic with a steel shaft between your knees.

i've yet to find the interconnection between the transmission linkage and the two perpendicular stalks which emerge from the steering column mounted shaft connected to the shift lever.

any link to a diagram or help piecing this puzzle together will be greatly appreciated.

thanks,

sid

Do a google image search for 1940 ford gearshift linkage. You will find lots of images showing the parts.

Re: three on the tree shifting [more scale model research]
 

you must be a better googler than i, because, while i did get lots of images for

parts, i do not understand "... the interconnection between the transmission linkage and

the two perpendicular stalks which emerge from the steering column ... "

He's back ....

Yeah, let us do all his searching and picking our brains but won't tell us a thing about the purpose. Reminds me of conversations with my boys growing up. -

- Where are you going? "someplace"
- Who are you going with? "my friends"
- Which friends? "the usual"
- When are you going to be back "don't know"
- Be careful and don't do anything stupid " yeah Dad, yada, yada ..."

btw: can i have an advance on my allowance?

Maybe this.

Re: three on the tree shifting [more scale model research]
 

thanks Bob C. that helps me get through the firewall and on my way towards the transmission.

the block i'm having is how the connecting rods attach and line of travel goes

from the athwartship to the parallel [to the transmission] rods. is there a type of

Heim fitting to make the 90 degree connection or ball & spring like a drag link?

i'm just not getting it. i run into things once in a while - and it takes me a while.

I’ll give it a try……it seems like you have a sense of humor………I think the last thing you ran into you might have hit a little hard….. There’s two flat pieces of metal perpendicular to the shaft going into the transmission….. the rod linkage from the steering column hooks to those……..Mark

Shifter on trans.

so would components #7285 & #7290 (left side of picture) work in a rotation

movement (as opposed to push/ pull)?

i used to work with a fellow in the boatyards and he would explain all sorts of magical things to me from his 55+ years in the trade.

he'd always finish the lesson with "you'll catch on if you live long enough"

such is my world!

and thanks for the close up picture.

Re: three on the tree shifting [more scale model research]
 

perhaps my (mis)understanding needs to go a little further up the steering column.

from memory, gear pattern is H with reverse high to the left (toward the operator) first straight down underneath, neutral is the - of the H, second up to the right of the H, and third straight down.

when the gear lever is moved, do the control arms at the end move in a rotation, or do the brackets and links allow them to . . . shoot.

i was almost getting it, but i still cannot understand how that motion is translated to the arms on the transmission in the picture Bob C posted.

from the neutral position on the shift arm, the levers can motion toward & away from the operator. from the R > 1st gear & 2 > 3 rd gear they can rotate, but, and i think i'm at least focusing the question, how are those two motions turned into rotation of the arms protruding from the transmission case?

whew . . . .

Re: three on the tree shifting [more scale model research]
 

S.E. : The slight rotation of 7285 and 7290 caused by the movement of the shift arms (7354) is transferred to parts 7280 and 7282 so that the shift arms (7231 and 7230) inside the transmission transfer the linear motion created to the synchronizers and gears inside the transmission to the desired gear selected by of the "H" pattern on the column shift.

If possible, get hold of a junk side shift transmission and take if apart one piece at a time. I bet there is a Fordbarner near you who can give you pone.

Re: three on the tree shifting [more scale model research]
 

i appreciate that because i finally (with some help!) understand how the linkage is connected (90 degree bend & cotter pin) so things are beginning to make a bit more sense. i'm at the "saturation point" and need some time to digest all this technical "stuff".

not sure i could wrangle a transmission, but there's three good car shows coming in september & october within an hour of home:

https://hotrodfallout.com/

https://ty-rods.org/

there's got to be at least one guy with a three speed transmission in the lot.

thanks for everyones help*

*except for the don't feed the troll guy. we'll deal with that later

Re: three on the tree shifting [more scale model research]
 

s.e: Sorry to report that I junked 3 worn out complete side shift transmission 3 months ago as you can't give them away and they are too heavy to ship. Surely, someone near you must have one they don't need. Visit some car shows and ask around -explaining why you need one.

Re: three on the tree shifting [more scale model research]
 

Sid, Ford passenger cars had floor shifts up till 1939, followed by column shift in 1940.
Many more hot rodders converted from column to floor shift than the other way around, due to the speed shift capability and durability of the floor shifter compared to the column.
With regard to your reference to Glennpm’s posts, he made an excellent point, we get lots of questions here and few responses to our own questions. With more detail provided in questions asked, we can deliver better answers, and we greatly appreciate follow-ups describing the outcome.

Re: three on the tree shifting [more scale model research]
 

Am I missing something. The missing pieces are called, I think, shift rods and connect the column to the arms on the trans. No one mentioned these ? Or did I miss something.\ ?

Re: three on the tree shifting [more scale model research]
 

The rods are in the first picture.
