    Today I was getting everything ready to put the 454 into my Blazer. I proceeded to clean the engine compartmente when I noticed the tranny was leaking pretty bad. After carefully inspecting it, I discovered that when I pulled the 350 out, the TV cable was snapped right where it enters the TH350 tranny. That's where the leak was.

    How do i fix this? The TV cable cover ends in a plastic "pipe" at the bottom which apparently threads or plugs into the tranny. This "pipe" broke at it's base.Can I just go to a parts store and simply order a TV cable? Does this replace from the inside or is it as simple as threading the new one in place of the broken part? Will I need to adjust anything afterwards?

    Any help will be greatly appreciated.

  2. I thought only 700R4's had a throttle valve cable? They may be called the same on a TH350, but work differently. If it is like the one on a 700R4, you will need to replace the cable. I had a really bad leak that I could tell where it was coming from and then finally I found that the TV cable was cracked where it mounts in the 700R4. New one fixed it right up !!

    sounds like you broke the kickdown cable. There should be a small 5/16 bolt holding it in. Yes, you can replace it from a parts store.

    Thanks, that's what I wanted to hear.

    Does this mean I don't need to open the tranny at all to fix it? Can you give me a description on how to attach it? Or is it simple and I should figure it out as soon as I'm able to see it? (Too much ATF mess today)

    Thanks.

    Hey, BigBurb, glad to hear from you.

    TV cable, kick down cable, I'm not sure. But it's a cable that actually pulls only when I floor it. Are this the same thing? How did yours mount?

    Say hello to Zack. How's he doing?

  6. I think it is the kick down cable you are talking about. A TV cable connects on the right side of a 700R4 through the area to the right of the body right beside where the dipstick tube is and has a hard plastic end and the cable goes through it and then connects to a lever inside the tranny then you insert the plastic end into the tranny and a little screw hold it in place. I don't quite remember on a kick down cable. It had been year since I messed with a TH350. Look in a Haynes or Chiltons book. I have an old kick down cable somewhere in the garage. yeah right trying to find that could be fun. !! Thanks for asking about Zac, he is doing pretty good. He catches every bug that comes and goes, but has been toughing them all out. Hasn't missed but maybe a week of school or so this year. He needs it so bad, he is really behind. God willing he will catch up when he is ready and stay healthy to whip this Leukemia crap !! I took him to the Indy 4x4 Jamboree and he got to ride in a monster truck and meet Mudzer and Steve Frisbie too. We had a blast !!

    If I remember right all you have to do is take the bolt or screw out of the cable hold down. When you get the new cable look and see what kind of an end is on it. The one, and only one time I have done it the end was a simple "double L" shape like a choke cable has. You just thread the double L through it, reattach the hold down, route the cable, adjust the cable, and bada-bing, your done. You probably already know this but <font color=red>DO NOT LET ANY DIRT FALL INTO THE TRANNY</font color=red> [​IMG]. If you don't know how to adjust the cable after you get it installed let us know.

    One more thing, when you thread the double L through the bracket inside the hole make sure you go on the same side as the old one came out of. Here is how to adjsut it.

    With the snap lock disengaged from the bracket, (by the carb) position the carb at wide open throttle. Push the snap lock down until the top is flush with the rest of the cable.

    That should adjust it for you .
