727 transmission with an ear or knob at the side? Help

[Hotrodharbor]

Hi Guys,

I have a 65 NYer and I need to replace the transmission. Since it is hard to get parts here in The Netherlands I only have the choice of 1 transmission that is for sale.
In my car there was originally a 413 but since i bought it what an stuck engine i replaced it with a 1967 440.

That transmission has a sort of knob on the side while other transmissions have an ear on that same spot.
Can somebody tell me what the difference is?

Those are mounting points for the shift linkage. Different cars used different mechanisms for the shifter. Mounting point doesn't affect internals

What is wrong with your current transmission?

I bought my NYer about 4 yours ago from California, it was a desert car that i saved. When i put the tranny in gear nothing happens. The wheels stay put.
I can turn the wheels by hand with some strength.
I have the car on stands and am working on it in the spare hours that i got. Replaced the engine, fuel lines. Now I am looking at the transmission. I am not a mechanic so i am trying at the best i can.
I replaced the transmission oil and placed a new transmission seal.

Does the rpm drop when you put it in gear?

 

[Hotrodharbor]

No nothing happens. It keeps running but the wheels dont turn. Also when i change gears. Even if i give some gas by hand, the wheels stay put. Nothing at all happens.

I'm not a mechanic either but I'd suggest you look into this trans issues before replacing it as replacements are expensive and more difficult.

Did you check trans fluid level in neutral with engine running?

Is the transmission the original '65 piece?
If so it is cable shift operated.
1965 teans is a 1 year only itwm.
Before condemning anything, make sure the trans has fluid and the cable shiftvis properly adjusted.

Thanks for your answer.
Yes it is the original transmission.
With replacing the 413 for a 440 I found out that engine brackets are a 1 year only so i had to make new ones.
So the trans is also a one year item? Was not aware of that.
And what is the difference with a 67?

I will look into the oil again, and the cables of the shifter. Maybe that is the priblem that i shift but the linkage to the transmission is not working.

Yes i did check the oil and replaced it with new one. But I will look into it again. I already did but maybe it partially filked the torque converter.

1964 and earlier TFs were cable controlled, but used pushbuttons on the instrument panel to select the gears. 1965 was the first US Federal mandate that all makers used a "common shifter and shift quadrant" orientation on their vehicles. Which meant the end of Chrysler's famous (post 1955) "pushbuttron drive"on non-floor shift TF-equipped vehicles, Ford's Cruise-O-Matic "D1 and D2", AND the end of GM's shift quadrant which had "R" next to "L". This shift quardrant conformity had been identified as necessary to prevent traffic accidents should somebody get into a strange vehicle and not knowing which gear was where could cause problems.

Chrysler's using a more simple cable rather than the later hard linkage in '65 was a transition into the legislated set-up. So, "one year only". As the internals had incremental changes.

Please keep us posted on your progress,

65 was first year for slip yoke and last year for cable shift.
66 and newer 727 have a different number of splines on the input shaft.
This broadens your choices of torque convertors and less expensive vs 65 and older 727's.
The 67 trans you have needs mechanical shift rods.
If you want to use the 67 trans you need to swap out the 65 steering column for a 66 column and all related shift linkages.
Or if console shifted, 66 and newer console and related shifter hardware.
But first diagnose your current trans isssue.
Hope this helps.

Wow! I did not know that! Thanks!

This helps a lot. Thank you. It also gives me the shivers since i did not know that a 65 NYer is so special with al the differences. Not looking forward to swap steering column. So as you said I first have to diagnose my trans issue. Will look deeper into that.

I did not know that. Thanks for the information, i learn every day.

If your trans is the original 1965, I certainly agree with looking into shift cable operation and adjustment prior to anything else.
@Tony Mopar may know someone close to you who can help

Yes thank you. I will first look deeper into the linkage to see what is happening there while shifting

^This^

Fluid check is done with engine running and trans in neutral. Consult the FSM for adjustment.
Don't have an FSM (factory service manual)? Download one here: MyMopar

Stupid question, did you forget to bolt the flex plate to the torque convertor?

Uhhhh i will check that as well. But I think I have. Thanks for your answer, with all those answers together I will get there

 

[oldkimmer]

Did u happen to change the torque converter? Kim
