tranny trouble?

I have an aod and today when I went to back up I felt a vibration under the floor. It backed up fine but it only happened in reverse. Any ideas? I just had new gears installed a few weeks ago too.

After the gear install did you/they put in some friction modifier?
If not, what you may be feeling is the rearend clutches grabbing.

I gave them modifier to put in but It just kind of constantly vibrated while I was in reverse. But then again the tranny has always shifted hard if I am in between gears while accelerating slowly and this time it thumped when I put it in gear...if that makes any sense.

Re: tranny trouble?

Are the shifter and TV linkages properly adjusted?

Then the first thing you need to do is to go out and buy you a Chiltons or Haynes Manual for your car.

Yes, just like he is showing and take the slack out of the cable.
However that is not recommended for the "final" setting.

The best way to adjust your tv pressure it to get a trans gauge and hook it up to the tv pressure port on the transmission, then start the car up and adjust the cable till you get 22 psi then your done...

Re: tranny trouble?

The link from trojan says 0 to 5 at idle and c4king says 22. Which is it, or both? Thanks so much for the help. I don't have the money for a new tranny so I would like to get it fixed so that it doesn't thump into gear occasionally.

To further confuse the issue -
Here is another procedure from Mustang Monthly:

Quote:
The best way to adjust the TV cable is to install a pressure gauge at the transmission’s pressure port and adjust the cable until the gauge reads 35 psi at idle in Neutral or Park. This adjustment is critical, because if you incorrectly adjust it, you risk transmission failure. See a trusted transmission shop if you’re in doubt. The rule of thumb here is shift quality. If the transmission shifts too soon, you don’t have enough cable tension. If it shifts too late, or not at all, you have too much tension.


If it were me, at this point I would find a FORD Service Manual and follow the procedures listed in it.
There is just to much discrepancy in the information I have researched online.

You go any higher than 25 psi, you will smoke your trans..

Re: tranny trouble?

Found my Chilton Repair manual and it reads word for word like this:
[B]
Throttle Valve Cable Adjustment[B]

Adjustment with engine off
1. Set the parking brake and put the selector in N
2. Remove the protective cover from the cable.
3. Make sure that the throttle lever is at the idle stop. If it isn't, check for binding or interference. NEVER ATTEMPT TO ADJUST THE IDLE STOP!
4. Make sure that the cable is free of sharp bends or is not rubbing on anything throughout its entire length.
5. Lubricate the TV lever ball stud with chassis lube.
6. Unlock the locking tab at the throttle body by prying with a small screwdriver.
7. Install a spring on the TV control lever, to hold it in the rearmost travel position. The spring must exert at least 10lbs. of force on the lever.
8. Rotate the transmission outer TV lever 10-30 degrees and slowly allow it to return.
9. Push down on the locking tab until flush.
10. Remove the retaining spring from the lever.


Now, no guage or pressure is mentioned in these instructions and I have searched online and saw like 3 different videos of how to do it and everyone is adjusting it with a different method. So I'm as confused as ever. I'm thinking it is only slightly out of adjustment because when accelerating full throttle it doesn't usually clunk. Usually only when I let up off the accelerator and its close to its shift point. Any thoughts on these instructions?

Re: tranny trouble?

At this point with all of the differing opinions on how to adjust it I would go to a dealer and ask them if they could print you out the instructions from their Ford Service Manual.

I think I found the problem. The assembly that the tv cable snaps into is completely missing. Never noticed that when I bought the car. The little knob is only sitting loosely in the hole on the throttle body lever.

Ok got my brass bushing kit and I can't figure out how it installs in the hole of the lever. The bushing fits in but how do I use the cotter pin to keep it in the hole. Or maybe I'm way off.

Picture?
The cotter pins that look similar to a hair pin clip around the post.
The straight pins insert through a hole and you bend the ends over to secure them.

That is a "hair pin" clip.
It should clip into a groove on the pin after you slide it through the bushing.
The bushing should fit into the hole on the lever.

That's what I was thinking but all the videos I saw showed the ball end snapping into a bushing.

If you have a ball end, then that clip and bushing won't work.

Not sure what other type of bushing I would need there.

Look at my previous post in this thread to see the picture of my cable end.

As best as I can tell from the picture the bushing and clip you have should fit.
The clip fits around the pin in the groove and the bushing goes in the arm the pin goes through.
You may have to drill out the arm a bit to get the bushing to fit if it is a repair bushing instead of a replacement bushing.

I installed the bushing kit and it is a 99% improvement. I think I might have it a hair too loose but no more thumping. Thanks for your help. Now to get that new steering rack.
