TV cable problems

[daved2]

Hey guy's I have a big problem and I have a Service manual. When it talks about releasing the lock tab on the TV cable I'm stumped!
I have no tab on my 1992 LT1 automatic 700r4.
When I hit my throttle the TV cable bottoms out before the throttle reaches it's full throw and I can't find any way to change it.
I need a 92 experts advice on this situation I am in. The guy who I got the car from had the whole ASR motor apart and I think he put something back together wrong because the TV cable should not bottom out before the throttle does and keep me at only 80% throttle with the pedal an inch and a 1/4 off the carpet and not going all the way down. I can see the TV cable and the whole cable moves plastic casing and all and bottoms out. It has a metal clip on it holding the cable together and when I take the clip off and pull it apart there is an O-ring and that's it no type of adjustment and the whole sheath moves inward when it bottoms out at 80% throttle. The book says there is a lock tab that should be parallel to the cable and you are suppose to flip it up, well I don't have a tab so I am going nuts trying to get this thing right.
I don't think the whole outside ( plastic coating) of the cable shouldn't move when the throttle is depressed just the inside steel cable should move, that's the way all other cables work anyway. I've never seen a cable work like this one does.
Any help would be greatly appreciated!
Thanks ahead of time for your time!

Isn't there a clamp for the outside sheath that locks the housing around the cable from moving? Maybe look along that area for where one use to be Should see something in the manual on this I would think, it can not be allowed to move or it will do nothing. Something has to secure it someway or another from moving that's for sure.

I found the problem, I never seen a button like this one. It looked like an H shaped cylinder and I didn't know that it was a lock mechanism and it wasn't locked down and that's what made it look like a strange piece to me. So my whole sheath was moving and I didn't see the button under it,( the flap that is) and I got it straightened out now. If I ever get it on the road I will see if it works or not. The guy I bought the car from didn't even know about that tab being flipped up and it's been like that for a while because there is no more clicking in the sheath as it is pulled in, they are all worn off I guess.
The shit you run into when you take over where someone else left off is just crazy.
But thanks for the reply guy!

glad U got it solved!

Glad you figured it out, I knew there had to be something that kept it from moving!

Thanks

Thanks guy.
Now where would I post that I need a new TV cable or TV cable and throttle cable?
I was taking to the guy at Corvette generations and he told me that those two cables are supposed to be connected to each other and sold as one unit.
Would I have to post it on parts wanted threads? I'm new on here and don't know all the rules yet.
Thanks

Not sure, we would just go to the dealership. There are some dealer affiliated members on here that may be able to help too!

Every dealer I went to told me it was discontinued, all the restoration places told me my only chance to get one was find someone with one or Corvette generations and they told me it would be a hard find if I did find one.
So I don't know what to do at this point. Usually the restoration places can get anything but not this because it was only used for 1 1/2 years, 1992 and half of 93 and I think I have a mixed matched setup and it's not right. My TV cable is bottoming out and keeping my throttle from opening all the way up so something is off and I don't know what except this cable, it has to be the culprit!

Thanks

Not sure without looking @ it but you might try

Without looking at it not sure either but there has to be a way to make and/or modify either the one you have or something close that is available and make a clamping device to hold the outer sheath from moving while still allowing the cable inside to move as needed. The adjustment for the whole thing would be according to where you lock down/clamp down the sheath while not crimping it down to where the cable would not move. Just look around for something close and come up with a clamping system to hold it in place for proper movement as required for it to work! Again hard for me to visualize without seeing it It would be really nice to see one that someone else has that is working to see exactly how it is mounted and held down. Maybe someone else will chime in here that has had this issue or at least has the same year, that would help a lot Wish I could help more, doesn't the manual show how this is set up?

Here is my cable, it is supposed to be attached to the other one beside it which is the Throttle cable coming out of the ASR, According to Corvette Generations. I have a clip in it and can lock it down but I have to push it all the way in which is how the book says to adjust it but it is a 1/4 inch away from the TV plunger with the pan off. Which it should be just touching the TV cam on the throttle body but when I move it where it just touches the cam I loose a lot of throttle movement. That will give me more throttle, about 80% so the cable must be too short or the throw is off in the ASR but I adjusted it by the book and moved my throttle cable too and that gave me a little more throttle as well but still only 80%

 

[hoosierdaddy]

Beats me

Maybe it is the wrong cable, is there a part number on the cacle?

 

[hoosierdaddy]

Beats me

Maybe it is the wrong cable, appears you could move further away, but really can't tell from picture! ADUST full open full close and then lock the housing in place.

I can't find any numbers on this cable. I can push it all the way in but that would leave it too far off of the TV plunger inside the tranny, I just got the tranny fixed yesterday so I can drive it today and see what the shift's are doing. If it shifts OK I might just get a TPI TV cable and run it to the throttle body instead of running it through the ASR.
This is just a bad situation with GM and everyone else discontinuing the cable and everyone is out of stock. People put LT1's in other cars and run that cable off of the throttle body so I don't see why I can't do that and if the ASR is on when it pulls the throttle back it will also pull the TV along with the throttle.
That's about the only solution I can come up with right now.
I just finished putting this car together from boxes and have no idea how it even shifts yet. But hopefully I will find out today!

Thanks for the Posts though, really appreciated.

Took it out today for a run. It will break the tires loose at 30 miles and hour just hitting the gas a little.
Something is wrong with my TV still. I adjusted it to the book and then by looking at the rod in the tranny making sure it is just touching the plunger at idle. While driving when I let off the gas at 40MPH the engine goes back to idle like I'm in neutral and I have to play catch up with the throttle.
One thing I do know is that I shouldn't have to play catch up with the throttle while in drive.
Anyone had that happen?
The engine just goes to idle but when I down shift it the engine rpm's stays with the speed and I can feel the car slowing down from the downshift and the engine rpm's stay with the motor in first and second but third is on it's own. Gotta be the TV adjustment huh?
I guess I will play a little more tomorrow with the adjustment. It is fast though and has some power already and only driven once so far so the rings are not seated I know that. Usually it takes a couple road trips to get power like this one has on the first run on the hwy.
It's going to be a fast one when the rings seat and I get these bugs worked out.

 

[hoosierdaddy]

Now that you can drive it may make it a lot easier to diagnose and adjust accordingly. You may just have it on the run now you can tell what is really going on. Good luck with it. There is a member on here that is an expert, c4c5 Specialist the BEST of the BEST maybe he will see this post and give you some things to check now that you are driving it!! Sorry I was very little to no help. I didn't look but maybe you should make sure this gets in the C4 posting section.

10163848 is the P/N for the cable. Google found lots of hits, but there isn't any stock.

The TV cable may be too tight if the trans is "freewheeling" at 40. Are the shifts late and hard at light throttle? If so, TV is too tight.

Proper TV adjustment is critical for a 4L60. Especially if it's too loose. It affects line pressure. If TV is not correct, the trans will be damaged by improper pressures. Usually burn-ups from low pressure.

 

[daved2]

All I have is first, second and reverse no third or 4th. I moved the TV cable around with no change. Everyone else is telling me the tranny has to come out but it was just rebuilt 5 years ago and sat in a garage and the guy let water get into it somehow. When I dropped the pan the first time the pressure regulator popped out and was in the pan, it was also all rusted. So I cleaned all the rust up, put a new SK700 JR kit in it and put it back together. I took it out yesterday again got up to 55 in second with no shifts after second., also no engine breaking in drive or over drive but when I shift into second I have engine breaking and everything seems fine manual in first and second. It's only when I shift to drive there is nothing there only acceleration and no engine breaking plus only shifts to second.

 

[daved2]

To answer your first question though, NO I can hardly feel it shift it doesn't bang at all.

 

[DaveP85C4]

Sounds like you have no 3-4 clutch. I agree with others that have told you "it has to come out".

 

[daved2]

Yes it does and it is out. Started about 10:00 this morning and just got done. Now I take it apart and see why there's now 3,4 working!

Thanks for the input though guy!
