700r4 shifting too fast
my 700r4 is shifting way to fast, crusing 35 im already in the highest gear possible, what would be a cause to this? i dont have the bracket for my carb yet to set up my tv cable right but i have it on the side of the carb and adjusted so it will atleast shift so i can drive it. and also do you guys have any tips on how to properly set your parking cable? i cant always get my car to go into park and it will start to roll untill i can crawl under the car to push it into park, suggestions?

Re: 700r4 shifting too fast
There is only one correct position for the TV cable and obviously you don't have it
And as a note
running with the incorrect adjustment on the TV cable can torch your trans fast

FIX that bracket. Driving a 700r4 with a stretched, or improperly adjusted TV cable will quickly degrade the transmissions life expectancy if not outright causing it to fail very soon.
The TV cable does many things, it is not "just" a kick down cable.
Read this, memorize it and think about driving your car without a proper TV cable: http://www.tvmadeez.com/article/index.php
A quote from the article:
"The TV cable used with the 4L60 transmission should not be thought of an automatic downshift cable. The TV cable used on the 4L60 controls line pressure, shift points, shift feel, part throttle downshifts and the detent downshifts. The function of the cable is similar to the combined functions of a vacuum modulator and a detent cable."

Re: 700r4 shifting too fast
I take it that this is the replacement transmission?
Driving the car with the cable incorrectly adjusted will eventually result in a dead transmission. The cable does not control shift points. It controls hydraulic pressure. Shift points are controlled by the governor.
You say that you're transmission is already in OD at 35mph. Does it shift through the gears pretty quick? I believe this indicates the line pressure is too low. Burnt clutches will soon follow. Purchase the correct cable bracket and adjust it correctly.

To aggressive and the high line pressure at lower throttle positions causes delayed, uncomfortably hard shifts. Set too soft and you get early shifts with low line pressure creating lots of heat, wear and tear on the frictions/steels. There is only one proper calibration, its not a setting you can mess with.
with engine off depress the detent cable button and hold, grab the black sheath behind the braket and pull it towards the firewall to "reset" the cable for calibration. Release the button.
Now, smoothly rotate the throttle blades till they hit the stop, if your detent cable is in good shape you'll hear it rachet or click. Some cables don't make noise, but you can feel the cable casing moving. Once the throttle has been moved to the open position you can release it and let it go back to closed.
Your TV cable is now adjusted, and your transmission will operate as it should. If you don't like the way it shifts do not adjust the cable in either direction. It has one proper setting and the procedure is designed to calibrate the transmission's throttle valve so it is synchronized with the actual throttle blades.
If after adjustment it still doesn't shift right either the cable is stretched and not calibrating properly, or there is something wrong with the transmission.

Re: 700r4 shifting too fast
The shift cable and the govenor are BOTH responsible for controlling the shifts.
The governor is how the trans "knows" how fast it's going; the TV cable is how it "knows" what the driver is doing.
You could look at it as, the governor tries to make the trans shift UP as it operates "more", and the TV cable tries to keep it in lower gears and add line pressure (to make the clutches grip harder.... which is where the short life when it's wrong comes from) as it operates "more". The whole thing tries to find the equilibrium point between the 2 stimuli.
Takes both WORKING RIGHT for it to shift right.

emo, go here and LEARN what's going on, and why it's important; and why half-a$$ing something half-a$$ed together sort of, isn't an adequate substitute for DOING IT RIGHT. I know this link has been posted for you before, go read it this time. Especially the "TV 101 Article" and look at the pieces that would fit whatever carb you have.

Re: 700r4 shifting too fast
well that didnt work, installed the bracket and its still not pulling the cable, im thinking i have too long of a cable( came from a TPI motor i think) or its streched, i ordered a new one from autozone for an 83 camaro tbi thats like 37" long. standard is like 43"

Re: 700r4 shifting too fast
Return the autozone one. They are junk. Buy it directly from the dealer.
Tv cables are like push-rods. Close is not good enough. You need the exact right part. I bought a tv cable for my l98 from the zoo. It was the right part number and matched the auto zoo pc. But it was the wrong length.
I learned my lesson the hard way. Gm part or no part in this situation.

Re: 700r4 shifting too fast
So far, we know there's "a wrong bracket" and "a wrong cable" and some hope involved. Other than that, we can't tell which of the first two scenarios is occurring.

Re: 700r4 shifting too fast
Iv looked at the article, EVERYTIME it's been posted, found out i needed the tv corrector bracket for my carb, bought it from summit, installed it and the tv cable has too much slack, hence me getting a shorter cable for an 83 camaro that's 37" long vs the tpi cable I had on it to begin with.

Re: 700r4 shifting too fast
I know, jmd; I shouldn't have even bothered with this guy, really. I usually don't because this is what his project always turns into. Nothing he ever does ever works like it's supposed to because he never does it all the way RIGHT, from start to finish. He always paints himslef into a corner, then expects to be spoon-fed everything, doesn't take the advice he's given, and complains about the cost of everything. As evidenced by his "tale of woe" there; trying every shortcut, half-a$$ing wherever he thinks he can get away with it, etc.
Some things, you just gotta do what it takes, no matter what that is. This would be ... one of those things. He just needs to quit posting questions, throw whatever he has now in the trash, go to Bowtie ODs, buy THE RIGHT STUFF for his setup, put it on, and be done with it, instead of all this mickey-mousing around with a bunch of unknowns.

Re: 700r4 shifting too fast
His delivery is less than effective.
You can't even tell us you bought a new bracket nor which one it was.
Which means no matter what he posts, you gotta have thick skin and good reading filtration ability.
And helping you is like herding cats.
Everything is a 2-way street. Take care of your direction of traffic and ignore the oncoming *******s unless they deviate into your lane.

Re: 700r4 shifting too fast
Yes Usually Sometimes Behind me somewhere Maybe. Taking one of your first vehicles from V6 to V8 is usually going to have some snags. I can't fault someone for not knowing it A to Z from the get-go. As for communication in both directions sucking, it's possible for all parties to try a little harder and accomplish something here.

Re: 700r4 shifting too fast
So the instructions for the carb. TV cable stud bracket that vetteoz posted worked, I assume? You never told us.
And your bracket is in place, bolted down by two intake bolts? You never told us really and you've never posted pictures.
And even when adjusted isn't able to be adjusted enough to make the TV cable(s) you have work? I assume this, but you really didn't effectively communicate. Thank goodness for my superior skills of inference.
And you went from a 1986 V6 TV cable which is too long to one for a CFI 1983 Camaro which is too short.
Yeah. Try one for a 4bbl (not CFI, not "TBI," not TPI) 1986 Camaro with an LG4 VIN "H" engine. I haven't worked with a lot of non-Q-jet 200-4R and 700-R4 apps. But when I have, the 4bbl TV cable worked.
Know what the most awesome part of it all is? That yo have a cable that's too long, and a cable that's too short. And you can truck those back to autozone to verify the new one is like baby bear's porridge; juuuuust right! Plus, you can measure between your correctly (I assume) installed carb. TV ballstud bracket TV cable attachment point and the TV cable mounting location in your nice new Edelbrock bracket and at least have a clue to go by when the parts guy hands you a cable that matches the description I provided above.
Maybe for Christmas, Santa will bring to my mind the peace and soundness of knowing you will have a nice used, long-lasting GM transmission, just like me and my POS cars! Good luck.

Re: 700r4 shifting too fast
Yes the information that was posted about the carb throttle bracket worked and is installed correctly as shown in the picture, the throttle cable bracket its self is held down by the back two far most intake bolts on the driver side. I can get pictures today when I go to install my new tv cable. The cables I have so far are one from an 89 TPI motor that originally came with my old transmission, then I went out and bought a new cable for an 83 TBI camaro, I haven't installed the new one yet but it looks really short, housing and cable wise. If I can't get the new one to install then I will get one for an 86 like you posted.

Re: 700r4 shifting too fast
Follow up. Got my old cable out today and it was just way too long, compared to the one off the 83, the 83 was too small, was too small, went to zone and got the cable for the 86 tbi vin h, it was just right. Got it installed and it rachetted out to where it needed to be.

Re: 700r4 shifting too fast
That bracket is for a TH350 kickdown cable NOT FOR A 700R4 TV SETUP. When looking for a bracket for my vortec headed project I looked at this bracket and discovered it will not work for a 700R4 (wrong geometry). I ended up modding the stock one, have not got the car running but my measuring says it is within factory spec.
Same bracket location. Different cable. See below.
Emo has adjustment of the bracket and TV cable adjustment to worry about, but the 8032 bracket is valid for his application.
