A4LD shift cable question

[Scott B.]

I am connecting the shift cable in my Ranger (A4LD) to the AOD I have installed.

I can shift the transmission from P -> 1, but not 1 -> P.

How does the shift cable upshift? What am I missing?

Thanks.

WAG #1....

Is it stuck in 1st?

Is it only stuck in 1st with engine on?

Something to do with the interlock?

Just a WAG, but if the AOD interlock feature is reverse of the A4LD, this maybe the issue. Like I said, just a WAG here.


WAG #2...

It may also be the cable bracket not holding the outer sheath to allow it to up-shift. Needs resistance on both sides of the cable connection to the mount.

Do you have it bolted to the firewall as well?

 

[Scott B.]

It is in regard to your WAG #2.

The cable is mounted solidly to the transmission, but I am not getting resistance when upshifting.

The cable is mounted to the trans the same distance from the shift lever as on the A4LD.

Okay...

So does the cable move at all on the mount when trying to up shift? Has someone else watched the cable at the mount when doing so?

Reason I asked about the firewall mount, is because that helps on holding the cable steady when shifting.

I'm sure you know all this as well, but when you have a million things going on at once, sometimes easy stuff is over looked.

 

[Scott B.]

The cable housing is solidly mounted - no movement.

When upshifting, the cable is pushed out of the housing, but does not push the shift lever - rather, it just forms a slack loop.

Sounds internal then. Sorry for getting the obvious stuff out of the way.

I will go ask someone I know that is a retired trans mechanic, who had a part on designing that trans with the Ford engineers, and see what he thinks. Get back to you later on this.

 

[Scott B.]

I'm an engineer - I always start with the obvious stuff..

Thanks!

The man says it is most likely the Interlock.

Same thing happens that you describe, when they break. Not uncommon he says.

 

[Scott B.]

OK - what's the interlock?

 

[gmanpaint]

Cast magnesium part inside the steering column that releases the shifter when you depress on the brake pedal to be able to move the shifter.

Only thing he asked that I could not answer was if you were able to move the shifter back up at all, with engine on or off.

 

[Scott B.]

I don't think I have an interlock on that truck.

And, yes, I can move the shifter both directions just fine.
