1964 3-4 shift rod length

Re: 1964 3-4 shift rod length

Agree, the frame mount was sometime in 66, checked with a friend on Sunday and his early 66 is still mounted on transmission. Now the 64 (3/4) rod was different than the 65 up rod, P&A Cats still list as different pn, however the newer rod will work in place of the older 64 rod, so that does not appear to be the problem.
Both the transmission levers should show the 3/4 or 1/2 numbers when installed. Perhaps you have the wrong mounting plate on the transmission, Doc Rebuild has a nice picture of what to expect.
The pictured set up has been used on the car for at least 15 years and before, 64 - 69 (before Hurst)

Alan, your picture shows the 3-4 lever in the "innie" position. According to everything I read, it is supposed to be in the "outie" position. In other words, the "3-4" that is stamped on it would be on THE OTHER SIDE once it is mounted.

I just don't believe that is correct. The 3-4 lever will not work in the "outie" position.

Re: 1964 3-4 shift rod length

Another ref is the 64AIM, sec M20 sheet 3.00 Note it shows both levers in the "innie" position.

Note; the position of the "Lever Brkt Ass" is way OFF from mine, it is rotated counter clockwise by some 90 degrees. In other words, the 5/16 locating pin is level with the upper 1/3 of tail shaft. Hope we are getting close to an answer, it's snowing here so cars are going back inside meaning no more pictures today.

And to add a little more mystery- the 63 pn was 3824815 (that was not for munci) then in 64 it started as 3850110, on 8/8/63 became 3853175, on 10/30/63 became 3857393

Re: 1964 3-4 shift rod length

Had to go out in the shed and find the shifter,

This shifter is a 65-67 shifter. The shifter body has the rectangular opening for the neutral alignment tool. 64 shifters did not have this rectangular opening. so I'm late to the party. Long rod is 3-4 shift rod

Also, the transmission shifter levers have two holes (long throw and short throw positions). 64 levers only had the long throw position holes.

Edward,

According to Alan's post the transmission shifter lever goes in the innie position so you don't have a problem, correct. When bolted to the side case, the transmission lever clevis hole clocks at approx the 1 o'clock position and your rod adjust properly.

I have the Noland book if you want me to take a look.

I am looking at the same page, as well as sheets 1.00 and 2.00 for M20 (1964) and my AIM shows the 3-4 lever in the "outie" position. It is hard to tell on sheet 3.00, but easy to tell on sheets 1.00 and 2.00 that is is in the "outie" position. I just don't see how that could work unless the neutral position of a 1964 shifter is significantly different than the neutral position of a 1965 and later shifter.

What would be great would be to see a 1964 shifter, off of the transmission, and set in the neutral position and a 1965-1965 shifter, also off of the transmission and also set in the neutral position.

I am wondering if the shifter internal arms for 1964 shifter are in the same relative position as the 1965 and later shifter.

Here is a 1965 and later shifter set in the neutral position.

Update: Disregard. I found a picture of a 1964 shifter set in pretty much the neutral position. The shift levers are pretty much in the same relative position.

Re: 1964 3-4 shift rod length

If anyone makes the rod for this transmission it would be Vette products of Michigan http://www.vetteproducts.net/.

They are the likely manufacture's of the rods for most re-sellers. Even do there own heat treating. Helped me out when I needed only one rod for my 63. The guy I spoke to was knowledgeable on the 4 speeds and was easy to deal with. Harry Sadlock send me in the correct direction when I need help.

Re: 1964 3-4 shift rod length

Does anyone have absolutely I know it is correct for 1964 1-2 shift rod that they can measure? The 1964 part number is different than 1965 and later. I am trying to figure out what the difference is

Re: 1964 3-4 shift rod length

64 shifter rod per prints in Noland's Book, page 235
1-2 rod, 3846851 L= 11.34, 3-4 rod, 3852922 L= 17.48
The later design in Nolanc's Book is on page 293
