700r4 lockup converter question....

Page 1 of 2  
I deleted/bypassed the computer on my '83 Z-28...... What do I need to do about the 700R4tranny? I think I need some kind of lockup converter wiring harness that runs 12v to the tranny?????? Is the converter not locking up?
Or does this just effect the overdrive? It shifts funny, its like it just glides into gear and it smells like something is burning, like a burning clutch or band smell...... it is supposed to have a shift kit and small stall converter in it (2600 or 2800), but you coudn't tell that by the way it shifts into gears, no "bang" or hard shift.... You have to pull it down in first or it takes off in 2nd or 3rd gear. and when you do pull it down in 1st it feels like it glides into 3rd gear or overdrive, skipping 2nd gear.... Anyone been down this road?

You did no benefit by bypassing the computer on your vehicle. Now you see why :).
The torque converter goes through (at least as far as inputs) go through the computer. Even in 1983, an issue with the TCC will send a code into the ECM's memory.
Put the computer back into the mix as it should be and things should go back to normal.
Why did you bypass the computer? You gain zero benefit by doing so.

For drag racing going away from computer controlled distributor and carburetors are the way to go. Heck even something like my 84 C-10, where the timing retards so much under load, you almost think you were running a 4.3 V6 not a 305 V8.
As for the OP: First of all, with no ECM, you need a after market stand alone PCM for the transmission. Not to expensive. A even lower buck set up is to use the vacuum switch and wiring from a 1986 G-10 or G-20 Full Size Van. While very low cost, it will only give you lock up in OD. Where as an aftermarket PCM will give you lock up in 3rd/D while at cruise speed.
Also you need to retain your Throttle Value Cable. With no or improper T.V. input the transmission will not shift properly.
As for a shift kit, if it has one, it's screwed up. Many a conn artist has sold a used car claiming it has a shift kit. Charles

You must not do any real drag racing. Not only is my Hemi FI, but its got computer controlled distributors on it.... Every serious drag car today has at least one computer on it.

I have to strongly disagree with you there Joe. The CCC used in the early 80's was very primitive and economy minded. Installing a standard 70's carb and vacuum advance distributor will make the car considerable more responsive.
The Canadian market '82 Trans Am LG4 was still vacuum controlled and is much more fun to drive that the US-market computer controlled LG4.

That's ignorance (not blaming you, per se, Dennis).
A CCC Q-jet can run with the best of them. In fact, it will run BETTER than a non-feedback carburetor due to better fuel control and feedback (which is why it was done in the first place). Sure, a M4MC/E is simpler than an E4MC/E but it's just because the latter is misunderstood. That's ignorance, nothing more than that.
An '82 T/A has a THM200 (3 speed in it) which is a mis-sized dog of a transmission for the car. That is the root cause of why it's a pig out of the box. In '83, the 700R4 came around and with some tweaking, even the early ones can shine pretty nicely.
A good performance guy can make an emission legal C3 vehicle dog a non-feedback one. Not only will it outperform a non-feedback one, it will get better fuel mileage and it will be lower in the emission department.
You just have to know what you're dealing with :).
The original poster already ruined the vehicle by going to a 750 Holley (from his post) and removing the computer. It's already a bastardized wreck based on those two events :(.

Its "old school" motor (no emissions) in a later model body...

Correct, which means it's illegal and you ruined it. LOL.

There's no reason to remove the emission controls to "gain power". That's a

This page says your tranny will overheat if you don't have the TCC connected.. As others have said, if the TV cable isn't there you'll need to get one hooked up.

Thanks Bruce..... My TV cable was unhooked, I will be hooking it up thanks to your post. Nice info, thanks again.

Definitely hook up the TV cable...and find a late 80's GM factory service manual that had a 700R4(like a 1500 truck) and reference the TCC wire circuits. The 700R4's were wired about 10 different ways under the pan. There are shift switches and pressure switches to either enable or inhibit the TCC solenoid even after the ECM would send power to that circuit. Wire it as you see fit for the application...according to the factory schematics... Doug

I think Joe lost something in translation.
Basically you took a erly 80's Camaro. Pulled the smog motor out, to replace it with a purpous built, high perfromance engine. Your Intention is a Drag Car, not a Street Car, or even a Street/Strip car. Correct?

Joe didn't lose anything in the translation, the original poster didn't state what he had and didn't state it clearly..
ANYTHING where the OEM equipment was a C3 system IS a smog motor. C3 equipment IS DESIGNED AS smog equipment and all motors IT is used on ARE smog motors.
If you say, "I have a C3 system on the car now", that vehicle was originally equipped with a smog motor.
Period. :) And you DID ruin it by bolting on a 750 Holley. A Q-jet outperforms it in all ways. Most folks don't understand them and replace them with Holley carburetors.
And, in theory, some pre converter 350's are still "smog" because they are made to run on unleaded gas and had hardened valve seats. Pontiac is one of those engines.
Tell us, John, what year did the Clean Air Standards start to take shape and manufacturers following suit ? :).

Now I disagree with you on Q-Jets vs. Holley's. Especially when it comes to Race Only vehicles.
When it comes to Carburetors at all the average Mechanic does not understand them. Which is why there used to be Carburetor shops all over the place. There are still a few around for that reason.
If my memory serves me correctly, GM started using hardened Valve Seats for unleaded fuels in 1971-1972. Also from memory I believe 1967 for Federal cars, and 1964? for California emissions.
In 1969 Some GM Engines came with 'Smog' Pumps aka A.I.R. Pumps. Including the Iron Block C.O.P.O 427 CID Camaro's. Which technically makes them a Smog Motor.
I'm also willing to bet most owners removed the Smog Pumps on those as their first modification.

I've always been a fan of Rochester Quads..... But I had a decent Holley around the garage. The 750 will be coming off shortly.

I'm sure most peoples guess would be somewhere between 1971 and 1973? But honestly that is trivia I have no use for..... Got anything more interesting? Like what year the band Motley Crue formed?

No, it shows your understanding (or lack of) on the matter. 1968 was the first year for many of the emisison type standards, many cars were "compliant" before that.
So in essence, many of your late 60's motors (including the one you run) are essentially "smog" motors :).
