Re: [FWDLK] PUSH BUTTON MECHANISM QUESTION

[Dave Homstad <dhomstad@xxxxxxxxxxx>]

Ed,

The short answer is "NO". There is no adjustment. All cable adjustments 
are done at the trans end.

As to housing to cable clearance: yes. When I put a 727 into my 56 
Dodge, I needed a newer designed cable end at the transmission, of the 
correct length to fit my car. So I purchased a repro cable, custom made 
length, for my application. I tried several times to adjust the cable, 
following the details in the shop manual procedure. Generally, it works 
properly, especially when cold. When things are up to the operating 
temperature, there are some minor issues. Sometimes Drive doesn't engage 
(from Neutral), unless I push the 1 or 2 buttons first, then Drive. 
Sometimes Neutral doesn't engage when going from Drive, unless I push 
Reverse first. Once Drive engages, all shifts work properly. I have 
never had a problem with "incomplete shifts".

By pushing the other button needed to get the trans to engage properly, 
the cable is pushing past the desired setting, and then when selecting 
the desired button, it is being pulled so slack between the cable and 
housing is not an issue.

The term for this issue is "hysteresis". It is caused by excessive cable 
to housing clearance. This allows the cable to flex inside the housing 
when pushed, so the movement at the transmission end is less than it 
should be when pushed, and correct when pulled.
