the TCC should not engage at all if there is no computer to control it. Unless you have a _REALLY_ early 700r4 that wasn't electronicly controlled..

but what I was saying if he unplugs the carb, the computer _MIGHT_ still operate the TCC system correctly as long as it still gets a VSS signal... but I can't say for sure that it will or won't. (never tried it) i've never played with a CCC/700r4 combo.. just the TH350c

It won't! The torque converter clutch solenoid will 'wander', and not engage the 'clutch' fully.

The TCI kit, installed correctly' enables a 2004R/7004R to engage the torque converter clutch in a non-computerized application.

Okay so what is this "kit" how much and where are they? "I'm not going to pay a lot for this muffler" I just had to say that, I remembered the old tv ad. Sorryhttp://www.hotrodders.com/forum/ I might just weld in a bung and forget I ever thought of removing the 02. If I do I'll have to keep fighting for better performance.

What do you mean the tcc clutch will "wander"

it's either ON.. or it's OFF.. there is no inbetween on a 700r4.

if the computer can't/won't control the solonoid w/o the carb, it will be off and stay off. but I was just thinking about it.. and you are right it won't be able to control the solonoid properly.. w/o a TPS the computer won't be able to appropriately time the unlock.. and if you loose the MAP too.. then it has no idea at all what to do except based on VSS.


find a wiring diagram.. you don't need to spend the $$$ on the kit (unless you want to, there's nothing wrong it it.. just $$$)

all you need is a toggle switch on 12v to the solonoid.. just gotta remember to turn it on and off yourself!

but then you also need a NON CCC qjet (those are easy to find) if you want more power, I'd reccomend holley.. I say again that I LOVE qjet's, but they don't take well to modified engines w/o finding a good carb shop who knows what they are doing. their biggest short coming being the incredibly restrictive fuel inlet design.... I miss my QJet for driving on the street.. but the holley performs soo much better on the track.

I need to tell you, I'm only doing thig as a learning experance, I will sell this truck if anyone wants it. I wanted to learn more about modern autos, and with your help I have. I think a toggle switch would work if I was keeping the truck. Since I plan to sell it I need to do a little better. 80 for the kit is the way to go. my next question is when I replace the CCC Qjunk and use a non CCC carb how will it connect to the trans?

At this point the check engine light, or service engine soon light will be on. The computer can no longer control the torque converter clutch accurately.

In installing this kit you take the computer command out of the loop. You get a new (2 pole)4th gear pressure switch to install. When wired 'up' it will only lock up the converter in 4th gear. The kit also comes with a vacuum switch, when hooked to a ported vacuum source, will only activate the clutch when vacuum is applied in 4th gear.

I use the power wire from the factory connector, and the replacement connector has a green wire also, that you can hook up to a brake switch to disengage the clutch also.

As a side note: The splice connectors in the kit are a pain to install. They are a screw together type, and they will push the wire out. I just use 'crimp' connections instead.

Are the distruction with the kit? I am fairly mechanically inclined (meaning I screw up a lot of things) and should be able to handle this with a little guideance. Now what is a good or should I say the better carb to use that is not a CCC and will I be able to remove the EGR and plug the hole? You have been a great help, Thanks.

The instructions are included!

As far as a good carb to use, the last one (I just did last Saturday) had a 1405 Edlebrock, manual choke I converted to electronic, on it. It was a LS1 5.7L in a 1989 Camaro RS. It got towed in from 70 miles away, and ran just fine driving away. It had no sensors at all on it, plain long tube headers, and a cleaned out catalytic converter.

Any carb of your choice will work just fine.

as far as your trans linkage goes.. as long as the non CCC carb has the same throttle arm on it.. they will interchange just fine.

if you switch to a holley, you need to get the correct brackets from holley to make sure that 700 works correctly.

I'm going to look for an Edlebrock 650 cfm I think I can find one that needs a rebuild for a good price. Is that the only items controlled by the ecm?

That diagram shows the 2 pole 4th gear pressure switch I mentioned that comes in the kit. Most, not all, came with a single pole switch which will need to be replaced.

I've heard lots of folks say this is the route to take, and get rid of the 02, EGR, and CCC carb. I'm game if I can get the wifey to loan me the dough.

yeah.. that CCC carb was just horrible from the beginning.. I wouldn't ditch the EGR if you can avoid it.. it helps with highway mpg's just a bit..
but I'm not sure how much trouble egr would be with a carb...
