1992 RS VIN E. Swapped in carbed 350, removed smog junk, disconnected ECM. Installed S-10 stall converter and the vacuum-controlled lockup switch.

Tranny already had a B&M shift kit previously installed. Before the carbed 350 install, you could feel the shift kit compared to my 1990 RS which is stock. And the tranny shifted fine before.

Now after the swap, tranny slips when your foot is in it, especially on 2-3 shift, and you cannot feel the shift kit at all, even on gentle accelerations you could feel it before.

I've adjusted TV cable til I'm blue - no change. Fluid level good.

Could the TV cable be stretched or something? I should have put in a new cable probably anyways.

Could the TC lockup switch not be right somehow? Not sure that would affect shifts - but I'm no expert - you tell me.

What else to look for? (a new tranny? LOL)

Any input greatly appreciated!

 

I bet the TC lockup worked before you ripped everthing out. Really a bad move to ripped everthing out. Go to www.700r4.com and read up on the TV cable stuff!

 

Why yes, the TC did lock before - however, there was also a computer locking it before - now there is not - I went carb and removed ECM, remember? I also installed the TC lockup switch necessary to lock the TC with the ECM removed. But, this should have nothing to do with shifts as I understand.

I've been to 700r4.com, and read it all many times. I've been adjusting the TV cable on my 1990 RS for 2 years with no problems. I also adjusted the TV cable on this 1992 RS before the engine swap with no problems.

And, I did not "rip" anything - I'm not some dumb 16 year old! 25 years ago when I was 16 and dumb, I still never "ripped" anything on a car. In fact, at present, every component necessary to return to the stock 305 TBI computer-controlled 170hp slow dog she was, is still in tact under the hood.

 

If what you say is true then the problem must with the S-10 converter. TCC should not be a factor until it is in 4th gear if the vacuum-controlled lockup switch was installed correctly. It sounds like you may have changed carbs during the swap also. If the TV cable is hooked to a different carb the trans will shift totally different due to the angle of the cable to the carb. Let us know.

 

I have a solution for you. put the TBI back on, hook the ECM back up. There are other ways to build power in a motor then just going to a carb. Get Headers, high flow cat, change cam, change the TBI intake, retune the chip etc. Get your self a new torque convertor.

Learn to accept newer technogy and work with it.

Every single new car sold today comes with some form of fuel injection, hum must be a reason!

GM eliminated the use of carbs somewhere around 1987, hum musst be a reason!

I converted my 1982 Pontiac Firebird to Tune Port Fuel Injection in 1998, hum must be a reason!

Now I going with a 4L60e computer controlled tranmissin, and hell there are lot of reasons, tuneable shift points, paddel shifter,
adjustable shift firmness, etc.. better MPG, faster acceleration.

Was you driving around today in a green camaro without the hood. I say you turning onto Cary Parkway.

I made a left hand turn onto Cary Parkway at the same time that you were makeing a left hand turn.

Was those three police cars after you!

 

Nothing wrong with carb's its just another method to reach a similar goal.

I'd guess its something with the TV cable being mounted to the carb now instead of the TBI unit. Its similar locations but there might be a difference we are not aware of. I would look if there is a specific TV cable or bracket other people with the same carb and a 700R4 have used. Or even look into the adjustable ones like Lokar. It could be something simple like a different bracket. I believe the TV cable affects the line pressure which can definately affect how the tranny performs.

 

Thanks, but no thanks. My 1990 still has TBI, and ECM, and I've spent months and months, not being able to drive her, since no one can do chips for a TBI. I refuse to do them myself, I spent years in computers, and I'm done with anything other than email, and these forums - even if I had the time to learn, which I don't. And after all these months, I can't realize the hp increases I made mechanically due to yet another damned microchip screwing with my life! I finally got 1 person to get me a chip that will allow her to run, very rich, very restricted, and very slow, but it runs, and gives me transportation. As soon as 01/06 gets here, the 1990 will get a brand new pretty carb as well! I have spent too much hard-earned cash to have my life restricted by another chip!

And yes, GM did install this junk for a reason, but it wasn't efficiency. For any carb tuned for performance will burn all the gas possible anyways. None of us, whether performance minded, or simply getting from home to work, want to be tuned rich. And if it had anything to do with oil economy, there'd be no Escalades, Hummers, or soccer-moms with 1 child in a Suburban (and you and I both know how many soccer-moms Cary has!).

And yes, that was me on Cary Parkway. But no, the cops were looking for someone else - I'm just too damned old - they know it wasn't me!

Anyway - I still can't explain why it worked fine before the 350 swap, when all that was changed was the TC lockup mechanism - guess that's why I'm not making big money building tranny's. I feel that I have just as good geometry on the cable as I did before - maybe the travel of the cable is different given a different linkage? I'll see if there's any way I can reduce or extend the amount of travel the cable undergoes.

Today I found a tranny guy in Fuquay - he's supposed to be good, maybe he can shed some light. I'll keep ya posted.

And good luck with the 4l60e swap - too much cash outlay for me - hell I could have another entire RS for what you're spending on a tranny controller! But, given that I have a freebie 4l60e sitting in storage, let me know the end results (and total cash outlay) when you're done.

 

As for your transmission, it may be working OK. I'm guessing maybe you S10 convertor has a higher stall then the one that you had with the old 305. If it does have a higher stall then you may not be getting the feeback from the power trand like you did before. There are special brackets available for carbs to to correct the TV operation.

As for NC state emissions beginning Jan 1, they will still be doing visiual inspections. They will be checking for presense of the check engine light, all emissions controls etc. They are just stoping the tailpipe test. Don't feel bad about the emissions. When I move to Wake county, I was forced into putting the Air injection stuff back on.

So just incase you find out that I'm correct about the emissions, then you may have a couple of options for you.
1) There are 350 TBI systems in chavy trucks, you might try to obtain a chip and ecm from one of them.
2) Convert to TPI.

Oh, have you hook up a scan tool etc to see what she doing!
I have such a tool, and might be able to help you. So if you're interested please drop me PM.

When I did my TPI conversion back in 98, I purchased the TPI system, along with the ECM and custom chip from a company in Texas. The TPI system was set up for my 350 Goodwrench engine, 2.73 rear end, etc

My engine converson cost me $7000 back in 98 using all new parts. I think it was well worth it. I still remeber the days with the old LG4 and I know I would not go back. I brought the car new in 1982, and I plan on keeping it.

As for computers controlling your engine, these are not PC's they are embedded systems. They do not run Windows, so there should be no frear of Bill Gates. Embedded systems are 100% dependable. I should know, I'm a Computer Engineer.

So I take it you did not see my bird. Here a picture from the side that you should have seen.

 

On the 1992 I've got a nice bracket, fully adjustable and very rigid, so bracket should be good. Like I said, The geometry should be all there, only thing different may be the actual travel of the cable, but I don't know if that matters.

On the other car (1990), I went with a carb intake and TBI adapter, and I actually fashioned a cheesy bracket on my own for the cables - it's definitely NOT pretty, and it works with geometry way less than perfect.

I'm not sure how the stall converter would change the actual shift, I see where it's going to change the shift point (kinda the reason for it), but not the shift itself.

Bruce check email - I talked more, but didn't want to abuse the boards.
