700r4 tci valve body

I’m no slush box guru, but is there a TV cable issue?

Any have any experience with set up. I just burned up my 3rd 700r4 less than 100 miles on this last one. I know others have made 700r4s work w/ a quadrajet. 3x less then 500 miles total for 3 transmissions. About ready to give up on overdrive.

It's all in the throttle valve cable. If not adjusted right you can burn one in a day
 
I have 70000 miles on my rebuild and it is all about the TV cable being adjusted right. I would go have a talk with your builder.
 
Yeah I hope that's it, and it didn't burn. Temp stayed around 160*, sensor in the pan. Fluid is nice and clear.
Gm made cars with quadrajet and 700r4,does quadrajet need the early vacuum set up?
 
the only vacuum you need from a Quadrajet is for TC Lockup. They were setup in linkage for that Carb with with the TV cable as mine was before going to TBI.
 
I have 12v ignition on signal going to 4 wire plug to provide TCC lock up in 4th. Trans was modified for this
 
So my builder road tested the snot outta my trans w/ me in the truck temp remianed below 200, 160 in 4th with TCC lockup. Shifts all correct. It acted up several times but doesn't seem to be trans related. Possibly fuel delivery. I have all rubber fuel hose from tank to pump, factory steel line pump to carb. Clean filter in carb, am gonna ditch that, and go inline. Planned on new sending unit so will drop tank and blow compressed air through steel lines on fram checking for any restrictions. Mechanical pump has fuel return on it may block that and road test.
 
rubber hose the whole length ? ? unless its fancy AN type hose ditch it . rubber hose these days sucks for life span .

No 3/8 factory steel for most of the frame, "rubber" line at tank, 6" in middle, and at fuel pump. Maybe 2' total, all replaced in Nov 18 with a new AC Delco mechanical fuel pump.
 
So after work today I pinched off the fuel return line at the pump, and went for a test drive I drove 5ish miles away on city streets at rush hour, 30 to 45 miles an hour. Truck ran great mild, moderate, even a bit heavy throttle. head to freeway on ramp up hill mild maybe 3-4 degrees, truck struggles, coughs, chugs no power, never stalls out I nursed it up hill 1-2 % feathering the throttle, hit the crest and the truck spooled up to sixty could even accelerate. what could up hill have to do with lack of fuel ?
 
I would be suspicious of the fuel pump just not being able to pull enough when the truck is pointed up even slightly. I had one do that time years ago. It would bury a 7 psi gauge when I dead headed the line with the gauge, but wouldn't pull the truck up a short hill. New fuel pump fixed it. It could be possible that your new pump is bad, but I don't know how you could check it easily. You would have to plumb in a gauge that you can see while driving, or swap another pump in. In my opinion.
 
I can t in a fuel pressure guage I suppose. my tank sender reads wrong, I have a new one. I the past I have found debris in fuel tanks block pick ups. Or 1 time a loose baffle that would block the pick up. So I am going to drop the tank and look very close inside, put my new sender in with a nice new clean pick up sock. Add an inline filter, remove or renew carb inlet filter. Hopefully something definitive shows
 
The sock filter its made of fiberglass or plastic and has such a fine mesh that water cant pass thru it,and that can lead to intermittent fuel starvation if there is some water in the gas,many times it gets overlooked as a cause because its "out of sight--out of mind"..

If you put an additional fuel filter between the tank and fuel pump,that sometimes makes it harder for the pump to suck sufficient fuel to the carb or fuel injectors..

I'm wondering if my diesel is starving for fuel at high speeds or under acceleration due to the sock filter--it was perfectly clean when I put the used tank in a few years ago,but since then I had one fuel filter (the big water seperator spin on one on the firewall),clog completely up and leave me stranded..

I cut the filter apart and couldn't believe how much sludge and tar looking crap was in there,and rust from the filter can--cant understand how those big pieces of gunk made it past the sock filter on the sending unit..
I also wonder how much of it made it all the way to the injector pump..:doah:..but it ran fine after a new filter was installed,until recently..thought the electric fuel pump I added that had failed was causing the fuel starving,but it still does it after by-passing it..
I may have got some dirty or watery diesel fuel..:(
 
If you have burned up 3- 700R4 transmissions, and the tv cable setting is correct, then you probably need to find another builder. I don't know what gear and tire combo you have but I have seen some instances where a 37-40 inch tire was paired with a 3.08 gear with predictable and similar results. These could also explain a low power or stuggling feeling that you have mentioned. Whatcha got?
 
His profile says 33's with 4.10, which is pretty good.
