About 700R4: cooling and TV cable
Hi all 
I've bumped into this page that anguished me: http://etereman.com/blog/general-mot...4-transmission
I'm about to buy a 1989 GTA 150.000miles with 700R4. The car runs great and gears shift fine. However, I would like to know how I can check the "TV cable adjustement", if there is a way.
Then, do you suggest to buy that aftermarket cooler? If so, where can I find one?
Finally, is there some kind of table/paper to check at what speed the transmission should properly shift gear?
THANKS!!

Re: About 700R4: cooling and TV cable
quick way to check the TV cable adjustment is to put the car in drive, accelerate slowly until it shifts to 2nd, then floor it and it should go back to 1st.
or you can just adjust it. it takes seconds.

The TV cable is NOT to be adjusted, it is meant to be set and leave it alone. If you "adjust" the cable, be prepared to dish out for a transmission rebuild. It is not a kickdown cable, it controls line pressures inside the transmission.
Here is what you do.
Depress the D shaped button on the TV cable, push the cable completely towards the firewall until it will not go any further. Then go inside the car and mash the pedal. With the car off of course.
Thats it, you're done! The cable is SET and thats all there is to it.
Just had to put it out there to save someone the trouble and aggravation of trying to adjust a cable that is meant to be set and not adjusted.
As far as part throttle shifting mph, that will depend on the governor, tire size, rear end ratio, etc, IIRC.
And yes, DO put a cooler on it, always a good idea to make the trans happy.

Re: About 700R4: cooling and TV cable
Its not just reading, its understanding that telling someone the tv cable is to be "adjusted" will lead them to believe that they can move the cable around and be fine, when in actuality it will cause the trans to burn up in short order. This directly from transmission builders who know what they are talking about. Ask anyone who works with a 700r4 or 4l60 if they adjust the cable or if they set it.

Are you going to foot the bill when he misinterprets what you told him and burns up his trans? Didn't think so.

Re: About 700R4: cooling and TV cable
No they arent straight because you keep using the wrong term. You set the cable and thats it, its not an adjustment. And no this is not the only thing I know about cars. It IS however something I push when someone mistakenly calls a "set" procedure an "adjustment".

and you set the TV cable by adjusting it.

Re: About 700R4: cooling and TV cable
I have always called it "adjusting", and I have only heard it called "adjusting" by transmission guys.
In fact I have heard them say to set the TV cable to adjust it by XXXXXXX.
I think it means the same thing really.
You "adjust" the valves on a hyd. flat tappet cam.. There is not much room for play there, you adjust it to the right point.
You "set" or "adjust" your timing.
You can not "set" the TV cable with out "adjusting" it to the correct tension 1st.
Again, I feel the play on terms is just semantics and in this cause botheans the same thing.

Just the way I was taught.
Yes you can adjust the timing one way or the other. But if you adjust the tv cable too far one way or the other what will happen?
The truth is some aren't too bright, so by mentioning that you "adjust" the tv cable, that can be misconstrued by some to mean play around with it. Which is a BAD thing when you talk about the TV cable on a 700r4/4l60.
I have gotten myself in the habit of referring to it how I was taught; you set the cable per the procedure and leave it alone. Yes semantics, they both mean the same thing, but one can be "interpreted" wrongly. Thats why I refer to it as a "set" and not "adjust".
Obviously you guys are smart enough to know this but some aren't and I err on the side of caution knowing this.
"So and so told me to adjust the tv cable, so I moved it 4 clicks further in, took it for a ride, and now I have no gears!"
See where I am going with this? Don't assume that person will do the research or understand the way something is explained. If you did something you weren't supposed to, that cost you money, then after the fact someone says "well thats not what I meant when I said that", how would you feel?

Adjust them too tight and could eat a lobe off the cam, break the bottom out of the lifter, bend the pushrod, break the rocker arm, bend the valve

Yes I do, and you are right. I know a lot of folks do not take the time to search out the info they need and can't follow detailed specs. Sad but so true.

Lol, how can you adjust timing too tight? Its either too advanced or too retarded, not tight or loose. Guess you mean valve lash.
Im just cautious when I do not know the knowledge that a person has.

Re: About 700R4: cooling and TV cable
Yeah I meant valve lash, by all mean valve lash.
Timing though you can adjust too retarded or too advanced and melt a piston, cause detonation, etc.

Re: About 700R4: cooling and TV cable
it's impossible for me to take part in this expert-dudes conversation 
I just would like to know if "big hammer" suggestion for checking the TV cable setup/adjustment is ok, that is:
<<accelerate slowly until it shifts to 2nd, then floor it and it should go back to 1st.>>
is this enough? Is there a paper or a video to compare a perfect 700R4 shifting gears with one's car?
I've read that when the transmission shifts too late there could be a TV cable problem. Question is: when is too late? At what gear?
THANKS guy

Re: About 700R4: cooling and TV cable
Just a mention, for a TPI car anyway, (after pushing the D button and pulling the cable back) you are supposed to open the throttle manually at the TB all the way to WOT. If you use the gas pedal, it's not precise. You will notice doing it at the TB you get a couple extra clicks, of course most cars will vary depending on the thickness of your carpet and how hard/far you press the gas pedal.
Doing it at the gas pedal will get you feeling awesome with the shift RPM but it's harder on the transmission. Do it at the throttle body then play with the shift governor to get the shift RPM where you want.

92GTA unfortunately I didnt understand what you said
I just would like to know if there exists a way to check if the transmission is correct shifting, and thus confirming that no TV cable issue is present.
thanks

Re: About 700R4: cooling and TV cable
The only true RIGHT way to do it is with a line pressure gauge, hooked to the test port on transmission.
But the common factory spec TV adjustment (or setting) is to press the D button, move cable back towards firewall, hold throttle wide open and let go.

Drive slowly under part throttle, as soon as the transmission shifts to second, mash the pedal. If it does not downshift to first, the cable is not set properly.

Re: About 700R4: cooling and TV cable
BTW, the Helms manual, which was used as the factory service manual back in the day, refers to "TV Cable Adjustment"...feel free to refer to page 7A -11 and 7A-12 in the '89 manual.

I assume that the person I am giving advice to doesn't know their way around a car, unless I know otherwise.
So when I know that a wrong setting on the tv cable will burn up the trans, I tend to steer away from the word adjust. That COULD, and I stress could, mislead someone into adjusting it one way or the other if they don't know any better.

The road speed at which the transmission shifts is dependent on 1) throttle opening, 2) transmission model.
Even if you have the chart and the transmission model, the road speed at which the transmission shifts is still a gross estimation.

Just had to put it out there to save someone the trouble and aggravation of trying to adjust a cable that is meant to be set and not adjusted.
As far as part throttle shifting mph, that will depend on the governor, tire size, rear end ratio, etc, IIRC.
And yes, DO put a cooler on it, always a good idea to make the trans happy.
Here is what you do.

Re: About 700R4: cooling and TV cable
Yes the 200 4r trans uses a TV cable just like a 700r4 and yes it must adjusted/set the same way

Re: About 700R4: cooling and TV cable
Here I am: I tried the test.
Went in second gear extremely slowly. Then suddely mashed the pedal. The car didn't shift down, it just accelerated.
That's supposed to be a bad sign.
However, everything else seems to work fine. In "Overdrive" it shifts down every time I floor it. In "D" also, except in second gear.
What could it be?
If the transmission at a risk?
Im going to put some videos in the next days.
thanks

Re: About 700R4: cooling and TV cable
expand your vocabulary, the correct terminology is "CALIBRATE".
which means "A PRECISE SETTING"
Once you calibrate the TV cable using the OEM specifications their is no need to re-calibrate it unless the TV cable is removed from the throttle bracket (such as when the transmission is removed for a rebuild)
you should never have to re-calibrate the TV cable if the intake manifold etc it removed.

Let me ask you this, why would GM incorporate and adjustment for it otherwise?

Re: About 700R4: cooling and TV cable
I didn't adjusted/set/calibrated it. Haven't done that yet, haven't never touched it. I've just received a 150k miles GTA two weeks ago.
As I've already said, the 700R4 seems to work pretty well overall. It's just it doesn't downscale from 2nd to 1st when you floor.
I'll try to post a video soon

Re: About 700R4: cooling and TV cable
Wow, how is all this arguing semantics actually helping the OP?
NiG
The fact that the auto wont change down to 1st at slow speeds would indicate that there is a possibility the TV cable is poorly SET/CALIBRATED/ADJUSTED
Follow the instructions (to the letter) published on the TVMadeezy link to re-calibrate it.
Its not hard, requires no tools, and you CAN do it easily without risk to your auto as long as you follow the instructions. Any problems after that would indicate cable or TV spring or auto issues. This is assuming the car had the original TPI/carby/intake/ linkage.
If a non-original carbureter has been installed there are geometry correctors that must be used.
Geometry is as important as adjustment where the TV cable is concerned.
Once the geometry and adjustment is correct then the people you are asking will have a better idea how to help you.
There is a plethora of information both on this site and on the net about the 700r4. It would pay you to read as many as possible to get a feel for your auto and its possible issues.

Re: About 700R4: cooling and TV cable
It's a steel cable guys, they only way you can loosen or stretch it is by exceeding the tensile strength of the steel. Or or it was taken apart or otherwise tampered with. There is no black magic to it, You set it and forget it.
In the 14 years I used my 700 in a street /strip application the only time I had to recalibrate it was when the trans was removed for a refresh / upgrade twice in 14 years.. the last version of my 700 I had upgraded with TCI's beast sun shell, 5 pinion planetaries, and servos. I sold my 700, which was still fresh, a few years ago since I wanted a more durable trans.
but I digress there nothing risky about resetting the TV cable. TO me it sounds like your cable is simply too loose. a Previous Owner probably tried to play mechanic and messed with it.
When you reset it you are simply increasing the tension on the TV cable which will increase the line pressure and restore the proper downshift. Any transmission shop can do this in less than 5 minutes, if you are too timid.

JUST SET THE CABLE ALREADY LIKE FRMULA88 AND EVERYONE ELSE SAID.
It's not rocket science and I work on rockets!
You'll be fine nig.....really.

Re: About 700R4: cooling and TV cable
Keep in mind that no amount of TV cable adjustment will make up for a worn out transmission.

Doesn't matter what word you use, you still set it and forget it. Calling it and insisting its this word over that word, when builders have used every word available to describe what the procedure is to set the cable.
No matter what word you use, its not gonna get you any extra hp or rep. Just set the damn thing and be done with it.
No hokum or magic involved, so easy a caveman can do it. Why argue terminology when you can help someone save their transmission?

The fact that it won't change down to 1st suggests that the cable is slightly loose. This means that your auto is likely to be running slightly less oil pressure than it should be.
If this is the case you are in danger of burning up the clutch packs in your auto.
If you don't want to touch it, print the adjustment instructions out and get your mechanic to do it as soon as possible.
