I know that the TV cable operates the kick down. Can any one explain its other functions. If adjusted wrong will it cause the trans to start out in other gears other than 1st or effect how the engine runs? The reason I ask about effecting how the engine runs is because I pushed the adjuster button and pulled the cable out a little ways to give some slack it the cable. I'm waiting on a friend to come over to help me adjust the cable. While I'm waiting on him I started the engine and once it warmed up it started to idle funny (I would idle down to almost stall then up to about 800 or 900 rpms) It didn't do this until i loosened the TV cable. Can someone chim in with any info.

first i have a question. is it called tv or tp cable? i hear tv all the time but the cable is the throttle position cable so i wonder if its widespread wrong.

to help its easy to set and a one person job. push the button on the side of the mount in and then push the cable tight into the housing in a receding fashion. then sit in the drivers seat and push the throttle cable to the floor slowly. the cable will ratchet out and set it self to the limit of the throttle.

it's tv

Both you and astro355 said to adjust the cable this way. Unfortunately on my van it doesn't work that way i have to press the lock button pull the cable nipple out as far as it will go then depress the accelerator peddle to the floor press the lock button in and push the nipple in firmly as far as it will go then release the lock button. I'm trying to up a video for you guys to see on how to adjust this TV (TP) (detent) cable. I tried to do it the way you guys said and it would not ratchet out it only limited the amount of peddle i have.

that sounds as if there is gunk of some kind in the button. not to say your way or my way is better or worse but do you think cleaning the button would help. i have never seen one that was two way action but i have not seen everything as well. just a thought

 

[Bertscova]

Ok here is the video of how to adjust the TV cable

I edited this portion out of a much longer video on how to install a transgo reprogramming kit

I'm not saying that the other way won't work just saying that this is how i have to adjust mine.

 

[Mr_Bowtie]

^That way seems like it would be too tight and cause the tranny to shift to hard or too soon?

I have always adjusted it like stated above by $uperJoe. I have always been told a properly adjust TV cable will let the tranny go into OD at about 50ish mph with normal accelerating.

But, maybe there is more then one way to adjust them. :shrug:

 

[Bertscova]

I just adjusted it like in the vid and it start of in first gear this time and left 2 black streaks in my driveway, wear as before it was starting out in second or maybe even third not sure. I still haven't been able to road test it because i don't have the cooling fan wired up yet still waiting for the thermostatic switch kit from summit. But will post the results as soon as i can road test it. The V8 swap is so close to being don't i can smell burning rubber :layrubber:

 

[Mr_Bowtie]

Can't wait to see how the whole swap turns out for you. Such a little part keeping you from going on a road test........ :banghead:

 

[Bertscova]

Yea Tell me bout it. I drove all over today looking for the style of switch i want but everyone has the ones with the probe that mounts to the outside of the radiator ( not sure i trust that style ) I want the type with the sending unit that screws into the water neck or into the sensor port on the radiator. I want true water temp not the temp of the outside of the radiator.
I ordered this one http://www.summitracing.com/parts/SUM-890015/ and i'm running a 180 degree thermostat

TV stands for throttle valve. The throttle valve in the valve body controls line pressure for the current gear in use. It does NOT control shift points or what gear you start in. The automatic trans (non-electric valvebody) shifts by line pressure. The faster you go in first gear increases the internal line pressure of the trans and will cause the 1-2 shift to happen. Having the TV cable adjusted wrong can increase line pressure to the point the 1-2 shift happens.

Either way of adjusting the TV cable will work. I think its personal preference.

And to do this, you need to slam the accelerator pedal to the floor, a quick action. If you do it slowly, you can bend the S-clip that attaches the TV cable to the throttle valve and that will make for a long day.

that makes sense. throttle position of the throttle valve. i was the one confused.

thats how i was told to do it as well. in a fast motion. i did and broke the plastic clip off the end of the cable. it was a long day that way as well. i was just suggesting slow so it didnt break as mine did.

I suppose that's a good thing it broke off while you were adjusting it as opposed to driving down the road and gunning it. You would have been replacing the transmission then. That cable should survive a lifetime of sudden accelerations.

Gotta love the old TV cable how well it boggles the mind sometimes.

Why wouldn't you put the on/off fan control sensor in the intake or head of the motor? Seems like a better spot to get the accurate reading of the motor then after the thermostat... :think:

 

[Bertscova]

You are right I can use the passenger side port on the head, I forgot all about that port. the drivers side has the sender for the gauge and there is a plug in the pass side. if i use the port on the head i won't have to use an adapter it should screw right in. Thanks for the suggestion.

TCI makes a valve body that eliminates the critical adjustment of the TV cable.Check it out at:

There are different types of sensors that are made. The older style (aftermarket) ones are made to mount in the radiator. It slides between the fins. That's what I am currently using on my van. They are more reliable, really. The only problem that you can run into is if you mount it too high in the radiator. If you mount the sensor in the very top of the radiator, you will not get an accurate reading. Coolant transfers heat better than air and if you have a little air in the radiator, the sensor will appear to not work as well. I mounted mine 10 rows down.

 

[Mr_Bowtie]

^Ok that makes more sense to me now..........they are meant to mount in the radiator didn't know that. :mrgreen:
