'66 Ambassador Transmission

  I just finished installing the new  TV cable into the transmission.   Making sure that the round spring that fits into the machined notch on the cable end scurely snapped over the valve lever from within the transmission, holding it securely.  The outer cable end housing was then bolted to the transmission.   On the upper carburetor side, I clipped the cable into it's bracket.   The cable is not connected to the carburetor yet.  I am going to search the TSM to find the proper proceedure for adjusting the clevis for correct shift points.   I noticed that the new TV cable slides very freely with no resistance as compared to the original one that I just removed.  Also, the cable slowly self returns  to the fully extended position, toward the front of the car , when I push it back in toward the transmission.  I guess that is the valve doing it's job.   If anyone can help me with directions on how to correctly adjust the clevis,  I would appreciate the help.  Thanks....  Dan.

That's the correct adjustment for all the cable controlled trannys. You shouldn't have to pull the throttle cable toward the throttle, the spring inside the trans should push it out. I guess it says that in case the cable is a little stiff. Hold the clevis between thumb and forefinger tip. You should be able to move the cable in and out (only moves ~1") easily. If you can't, the cable is too stiff. The cable will only move so far, so pulling it out toward the throttle doesn't hurt a thing.

You can go up to two additional turns (four turns total) longer. That will provide a bit firmer and quicker shifting. Four might be too long though, it was on my 196. If it's too long you will go up hills in second gear when you would normally go up in third. When the cable bottoms out (in all the way) and the car is under a certain speed (controlled by the governor on the trans output shaft) the trans will kick down into second (passing gear). Four turns total may work with the V-8, but the 196 required too much throttle going up hills for more than 3.5 turns longer.

Adjusting my pressure is the "proper" method that nobody ever uses.

Adjusting for loose pin fir at curb idle plus two turns in the initial setting which works fine most of the time.

Fine tune them by shift feel. A long cable will make late and hard shifts. A short cable will make early and soft shifts and in severe cases, transmission slippage.

I have mine adjusted for loose fit plus 1/2 turn just to give me room to adjust the idle speed. Still shifts too hard and late for my taste, but I can't make it any shorter so that's as soft as it will get.

I've never seen a BW automatic shift 2-3 smoothly. I'm not a fan of them.

Older post, but this was very applicable to what I'm doing on my 65 Marlin...

No, I removed the bolt and could easily remove the cable. I bought the car 2 years ago and immediately started working on it. They rebuilt the engine in the US in 2015, I think they never hooked up the tv cable after that. The bracket at the intake was also missing.
