How to : Adjust TV Cable on 700R4


My TV cable is completly loose on the 84 Z28/LG4. Kickdowns are all over the place, and I've lost 4th gear. What is the prescribed manner in which to adjust the cable? Thanks!!

Press the D-shaped button/tab/whatever on the side of the TV cable at the carb. Pull the black cable sheath that comes from the trans away from the carb. Then go in the car and slowly depress the gas pedal all the way to the floor. Toward the end, it'll get hard to push, but keep going smoothly. All of a sudden it'll click and you'll feel a snap in the pedal, and it'll go to the floor. It's all adjusted.

*note: This is how it is on TPI cars, but I can't imagine the routine being any bit different on a carb car.

To adjust the TV Cable skip the book method and do this: Press the 'D' shaped lock button on the adjuster and loosen the cable setting (The black housing that the metal cable is in will move forward). Now, have someone floor the gas pedal while you check to see if the throttle plate is open all the way. Usually they are off a little and will wiggle. Do whatever you have to do to get it open solid. Now, with the pedal still floored, press the 'D' button and pull the cable casing (the black tube) back as hard as you can (putting maximum tension on the metal cable) and release the button. You now have the engine, tranny and gas pedal all in sync at WOT. Mark the cable casing so if for some reason it gets moved you can know where to put it again. The problem with the 'self adjust method' is that it bends things and puts them permanently out of whack. It is also the full TV setting, which is theoretically what the GM method does.

i was gonna b asking the same question... but i wanna make sure i have the right reason as 2 how to adjust the cable..

im no expert on tranny's at all.. i did a fluid and filter change bout 2 weeks ago.. and as of late my shifter has gotten real "playful".. meaning when its in gear there is alot of play within it... the stick physically moves id say 1/4 to 1/2 inch but will stay in Driver or reverse or wateva its in... now when its in park it seems like there is somtin pullin it back so as soon as i push the button its almost immediatly goes into reverse...

is this a TV cable problem?

its a 700r4 auto (Duh)

im gonna post this as its own topic also jus to make sure people see it.. so feel free to answer either of em..

thanks guys...
