Alright guys. my 1-2 shift was as slushy and god awful as it could get w/ my 700RJunk. It would shift out of first, sort of float in between gears for a moment then shift into 2nd. So a friend of mine adjusted the TV cable. it was about 1/8 of an inch "out" of adjustment. The shift got 100% better and was nice and snappy from 1st to 2nd gear.

Then all of a sudden it got a tad mushy again doing the same thing it did before with less of a pause in between shifts but it was still very obvious. SO we adjusted the cable again. The shifts went back to fairly snappy.

Now it's back to it's sloppy friggin 1-2 shift AGAIN! What am i doing wrong guys? The 2-3 feels decent considering the trans fluid is brown-ish even after a fluid and filter change. my buddy that set the TV cable knows what he's doing but we can't figure out why it keeps coming out of adjustment. The cable does have one or two strands broken away but the rest is there and intact.

Do these cables stretch that quickly or is it coming out of adjustment due to a bad cable holdown? I can't tell but i have plans to change the cable when i change from "C" code intake to the "J" code that showed up today.

Anyone know where i can get a TV cable for a diesel 700RJunk trans?

I'd love to swap to a manual but i don't have the money right now so this 700RJunk has to last me at least the winter.

Lol....ya the cable is shot, it keeps moving on ya.

JB weld is your friend.....get it setup and glue it!!!

I scored a like new cable with the 6.2 i bought....im not selling it as i know how hard they are to find.....

Dealer's should stock them right or at least be able to get one i hope? The parts guy at the local GM dealer is really good at his job and genuinely wants to help and make sure i get the right parts.

I love how this truck's got low miles on it yet it's all the little shit that continues to annoy me. Should just swap to a SM465/NP208 and be done with it. damn 700RJunk.

By all means, get a new TV cable, $35 at the dealer. I had the same problem, cable going out of its position over time, two strands broken. I kept messing with it until it wasn't funny anymore, then finally got a new one --- and found I should have used a new one right away.

There is nothing to adjust on the TV cable. You install it, then push it all the way back in the clamp, move the throttle lever all the way to the open position, and that's it. You set the TV cable once when installing it, you do not adjust it.

i went to adjust it again for shits and giggles. i got the same results. first 1/2 of the test drive nice snappy 1-2 shift. 2nd half of the test drive shitty 1-2 shift. :mad:

oh well, time to park it until i get a new TV cable. this truck's going to be my primary transportation this winter, so that 700RJunk has to last at least that long. i can do the 4-spd swap once the 700R4 gives up the ghost. i jsut can't see sinking any more $$ into it when i found metal flakes floating in the pan and almost brown burnt to hell trans fluid.


Does the new cable come with a new "holder" w/ the adjuster mechanism in it?

Put a TH400 in it. Probably cheaper and easier than a stick.

If you are interested I may be selling the one out of my CUCV at some point. It appears to be in good order. I could use the dough to fund a TCI controller.

Brown fluid is not that big a deal. The new stuff turns brown quickly. A little metal in the pan is normal, big flakes are bad. And a squirrely TV will fry your trans. Sounds like the ratchet is not holding on the cable.
At the plant we set them by going to wide open throttle once. Adjust no more than 2 clicks on the ratchet from there.
Don't go the 400 way unless you're towing. Unless you're running way too much turbo the 6.2 is incapable of breaking a properly set up 700.

i surprised there's no photo of the 454 blazer killing that 700R4 while doing burnouts in front of the police station like you told me. ):h i'd pay to see that.

dave if you do go to a manual get a overdrive tranny. like a NP833 since your rear gears are set up for a overdrive tranny as it is. otherwise your engine will really be howling with a direct gear.

If you can find a cable for $35 thats great!

I almost gaurantee it wont be "in stock" wherever you go.

Even my 99 Jeep tv cable they had to order.

Yes but 3.08s are a tall gear. on the highway the blazer's pretty much at a high idle and it's under 1500 RPM on the highway it sounds like. Need a tach to tell for sure. 4.10s would cause the truck to scream. 3.08s are highway gears.

ahh i figured it would have 3.73's in it like my truck has. at highway speed judging by sound its doing around 1900-2200 thats at 75 and the turbo is spooled up nicely so the dirvetrain combo is killer in this truck. only thing i want is a low gear. and a lower reverse those gears are too tall as it is. but with a SM465 in your blazer youd have that low to start off in and then a direct. sounds like a lovely idea just put a 205 behind it :D

Does the new cable come with a new "holder" w/ the adjuster mechanism in it?

Yes. The holder/ratchet is what's worn out so that the cable doesn't hold its set position. It is part of the cable. They'll have to order the cable for you.

When you take it off of the transmission, put a suitable container under it to catch transmission fluid that could run out. It didn't run out on mine, though. There's a small wire with a hook on its end in the transmission that hooks into a loop on the end of the TV cable: That can take some fumbling to get the new wire hooked up; other than that, it's easy.

this place has them in stock.

thats a gasser cable......it wont work.

Just got done doing that on my new tranny in my truck......even though i told him it needed a diesel tv he stuck a gasser one on it anyway......i only had 1st gear. 3 weeks later i found out he used the wrong cable. Truck was out of comission for that 3 weeks.

got a used diesel tv and everything magically worked.
