Ok tgo what am I doing wrong? I have pics below 1. At rest and one at complete W.O.T. Now the black plastic that is supposed to slide out that has the notches on it is not pulling out. The tv cable at rest is straight and has little tension. If pull on tv cable anymore any little bit u can hear a valve opening down at the tranny so I don't want to stretch it any further or am I wrong? Should it be stretched further? I will get a measurement and let u know how long it is. Edelbrock performer rpm intake, edelbrock 1411 carb, stock throttle cable and stock 700r4 tv cable. I kon we're at WOT b/c I took everything loose from carb and marked where linkage stopped and connected errything and it returned to same spot when pedal was pushed

If you open the throttle all the way as shown in your photo, the TV cable should be tight.

Open the throttle all the way and then pull on the TV cable. If it's not tight, the cable is not adjusted correctly.

Don't force the TV cable when you're pulling on it.

Paulo is correct. Make sure that the throttle linkage is actually going to the WOT position when you press the pedal from inside the car.

Start by depressing the D shaped button on the TV cable housing and push it all the way back towards the firewall. After you do that, go inside the car and mash the pedal to the floor and you should be set. With the car off obviously, lol.

The TV cable is NOT an adjustment. If you attempt to adjust the TV cable, there is a 99% chance you will burn your transmission in a very short amount of time. The TV cable is something that needs to be SET, once it is set you do not adjust it to change the behavior of the transmission.

Just something that needed to be said. Once you have set the TV cable position, you can move the throttle linkage to the WOT position under the hood and feel the cable, it must be tight as Paulo said, if it is loose there could be something amiss. Could be improper length of the overall TV cable, worn out TV spring, improper bracket geometry, the list goes on.

More pics. Now it won't shift at all stays in 1st

willexoIX

How many miles on the transmission and is it modified in any way? Like shift kit etc?

Original motor and or carb? Motor and trans out of the same car, or both original to that car?

Has the TV cable been replaced at all? Are you doing the TV cable set procedure with the gas pedal from inside the car? Does gas pedal WOT match manually rotating the throttle linkage WOT?

I am thinking that you may need a TV geometry correction bracket if using a different carb then stock, unless you already installed one. I cant tell if you have one hooked up or not because I am using the original TB on my car.

If the TV cable length is correct and you have a correction bracket in place, and you also have the TV cable set properly I would be led to believe that the problem could be elsewhere.

What led up to the issue that your having? Motor swap? Carb swap etc? Was it working properly before said mod was performed?

The 1st pic with tape measure is the throttle at rest. The cable is no slack but no tensiion meaning no extra pull on cable, remember that I said any extra pull on the cable with throttle in rest position I could hear and feel the valave open at the tranny. Now I can continue to pull it out by sliding the part of the (throttle bracket) back some more but that would also pull the cable out the tranny also I mean someone correct me if I'm wrong.

I can pull it to the back of thr brecket and even change the pisitioin of the extra bracket plate that its bolted to (look at pics its one of the cheap brackets from summit) but how far back? I had it about 7in out at first and when touch the pedal it startted pull the black plastic clicker out immediately. Then the car shifted into third at 10mph and that's not right either. I kno not to drive it till I have it right but don't kno how far to start off with

Now I feel two different detenses one at the first measurment and the 2nd one at about 6.25in of length but should I put that much pressure on it before I set it in the above procedure. That's what I'm asking? I need to do video!

3.1 to 357v8 with 750 eddy carb. Both trannys 700r4 but first one for v6. Car 91rs

willexoIX

Not sure on the proper positioning of the TV bracket for that carb, but someone might chime in. I would google "750 edlebrock carb TV bracket setting" and see if anything comes up. If you got the carb from summit or somewhere like that you might be able to call and ask. Dana from Probuilt Automatics checks this board frequently so he may chime in on it as well.

Sounds like you need to find the correct mounting location for that bracket. I am not well versed on carbs so I will leave that to a more experienced board member. Don't give up, someone will have the information you need. I would call the carb manufacturer and see if you can get any information that way, along with google and you might find what your looking for.

One more question though, are you using the TV cable from the V6 trans? Different motors came with different length TV cables, so that could also possibly be your issue.

Good luck, I am sure someone else will chime in with some more info for ya.

Dagnabbit. I did not think of that. Diff. Motor were diff lengths but I will say this its the tv cable that came with the v8 tranny. The tranny came out of a trans am with about 80k miles and I built this motor for a 305 89rs swap and switched it to this 91rs body b/c it needed almost no bidy work. The tranny worked beautifully in the 89 body with the same cable it has now (the one it came with). Performer rpm intake.

just thought of the question that I should have asked at first. what is the at idle length of the TV cable when on a LO3 engine? that will tell me where to start.

the story: I bought the 1st Camaro as an 89rs with a lo3 I got this 700r4 from wagner auto salvage in durham,nc with a 30day warranty for $450 it has done beautiful. I couldn't get the lo3 to run right and decided to build my 357 after finishing it the tranny got paired to it unsure of my "getting it right skills" I let a mechanic do it for me using this same carb and $600 and a lot of pissed off later the tranny did fine. so a year ago I found a 91rs that is in gorgeous shape so I got it b/c It didn't need the $7000+ to get the body and int. right so I took the 357 and auto tranny out of the 89rs dropped it in the 91rs that had a 3.1 in it and now this is where we are. I refuse to pay another $600 just to hook up the tv cable and turn(tune) the air/fuel mixture screws

willexoIX

No clue on the idle length. But if you just pulled the motor and trans out of one car and dropped it in the other I can't really see where something would have changed, especially when it was fine before. Maybe the bracket for the TV got bumped or the cable got stretched or kinked somehow. Could really be any number of things. Was the TV cable removed at any time during the swap or did you swap everything over in one shot all together?

Just trying to get more information in your thread so someone can chime in.

hey thx for the help no prob on the ??? I appreciate it. when I swapped the motor to the 91rs I took the carb off and the throttle bracket. like something silly I did not measure the distance between the mounting plat and the carb throttle (I should have) and right now I would not be going thru this. this is the bracket: http://static.summitracing.com/globa...um-g1414_w.jpg

One thing I do to double check that neither is interfering with each other is to disconnect the TV cable and extend both the throttle and TV cable to make sure that they match up independently. Then, I also feel how well the cable retracts. The cable on yours appears to have a kink in it and if it's bowed before that, it may cause it to hang up. Could also follow the cable down and see if it has too much of a bend in it somewhere.
Another thing is if the bracket moves during the adjustment while the throttle is being extended the set up would be off. Mine would do that once in a while (even afterwards) and I had to make sure it was secure.

Otherwise see if you can find someone local that you can compare with to see if there are any differences. Then you can measure and also feel for any differences first hand.

I'm not sure what that means. If the TV cable is hanging up or installed incorrectly it may not allow the throttle to move all the way. If the bracket moves after adjustment then the cable will move farther than the throttle.
When having trouble with anything you can often find the issue by splitting up components to see if there is an issue with either one. You can also feel the pull on the cable better.

willexoIX

In that case I think Scorpner means to disconnect the TV cable from the throttle linkage, then rotate the throttle blade to WOT and pull the TV cable out at the same time to make sure nothing is binding either one.

To locate the TV cable bracket, I would do this:

1. Remove the TV cable from the carb linkage.

2. Move the TV cable bracket as far to the rear as possible.

3. Move the TV cable adjuster as far to the rear as possible. Pull the TV cable to the end of it's travel (do not allow the adjuster to ratchet) and open the carb WOT. The end of the TV cable should be behind its attachment point on the carb. This step ensures that the adjuster has enough "pull" for adjustment.

4. Pull the TV cable adjuster all the way out until it stops. Pull the TV cable to the end of it's travel and open the carb WOT. The end of the TV cable should be now be in front of its attachment point on the carb. This step ensures that the TV cable isn't over-pulling down inside the trans.

5. Return the TV cable adjuster to it's full back position.

6. Attach the TV cable to the carb.

7. Open the carb WOT and allow the adjuster to ratchet out.

8. DONE

You might have to play with the TV cable bracket position to get both conditions described in Steps 3 and 4. These two steps will put the cable adjustment in between its travel limits. The actual bracket location isn't critical as long as it puts the cable adjustment in between its travel limits.

If you cannot get both conditions described in Steps 3 and 4 either the TV cable is too long or the linkage geometry at the carb is incorrect.

If you do get both conditions described in Steps 3 and 4, and the transmission will not shift correctly, the linkage geometry at the carb is probably incorrect.

Don't discount the TV cable bracket to be suspect as well.

Kool, willie thx, and pqaulo u won't beleev this but I thought about that very procedure on the way from work. I did some measureing and ur right I am a little over 5/8in too close to the throttle linkage that's what's wrong. I thought about and the cable when slider is all the way in still has to pull 3/16in past the cable stopping point so just back it up (duh david) I feel like a dunce. This car has whooped my butt with the simple things. I will try it tomorro and report back. Hey fellas ans TGO thk u

budget builder

iTrader: (3)

consider this solved: I did the measuring yesterday b4 I read Paulo's post and found out that to move the full range of travel and still have the 3/16in for WOT I have to move the mounting plate for the bracket back about another 7/8-1 1/16in somewhere in that area (duh) I do feel like a dunce then I can do the "set" procedure thx fellas. I appreciate the confirmation Paulo

hey fellas one last ?. how hard should I have to get on the gas b4 the tranny downshifts? I got on it pretty geed last night and didn't feel it downshift.

upshifts felt just a little soft but I take it that's not bad enough to worry about.
