First, the obvious. How's your cable? I mean is it correctly adjusted? How about fluid? Correct amount? Color OK? any burnt smell? When was the last time you change the fluid?

Let us know what you find, or found already. We go from there.

When I had my cable out-of-adjustment, before stock rebuild on my KZF trans, showed similar symptoms. I had Eddy carb with corrector bracket. Only different thing was mine stack shift from 1-2-3 real quick.

Check out Extreme Automatics web site. There is a lot of info there on how the system works.

Shift performance / function is directly related to line pressure in the 2004r. Most important is setting the TV cable.

Here is a good write-up on the TV cable. https://www.cpttransmission.com/tech_tvcable.htm

You can watch some YouTube videos to actually see how they're set. It helps to have 2 people - one working the gas pedal and the other unlocking / locking the adjustment clip. I say this because sometimes the range of "full throttle" at the pedal may be different from rotating the throttle at the carb all the way open.

Also, since you deleted the computer, you're going to need something to lock/unlock 4th gear on the converter. I went with a Bowler system.

Hi I'm back, dropped pan,fluid looks good and no major peices etc. Dropped gov, everthing looks normal, verified CZ tranny and SS govenor. also had friend push gas pedal down, verified 100% TV valve actuation. OK so, part throttle driving is lil late but OK, what the car does in drive full throttle takeoff ,it immediately short shifts early, then 30 to 40 mph, it will downshift to 2nd wind out to at least 6000 rpm and continue! people say adj gov weight idk... i'll figure it out eventually, oh yeah installed holley adp correcter also not much diff either

I would pay particular attention to the TV cable connection at the carb. It's critical that the GM location of that point on the carbs linkage is duplicated on the Holley. Middle of the PDF page below. If you still have the old Qjet take measurements and visuals from it.

We had a Bowtie Overdrive 200R in a 67 Camaro, he insisted on a Edel Performer carb. The TV adapter kit for the carb was all wrong, angles and radius, always adjusting to no avail. I built him a Qjet with factory TV and all is good. Set it like the factory says and go.

BTW, I forgot to ask in my first post. Was it doing from before or did it just started?

If just started to do this, did you do anything to the car? If it was doing it from before, you may want to look at (in) valve body. Maybe broken spring? When I did my CZF (still under the house, waiting for that last step of the rebuild), I think I had two broken spring. It did drive fine with broken spring, but acted somewhat strange once in a while. It has been rebuilted using evilbay rebuild kit with CK trans parts with their shift kit. Just need to complete the rebuild and slap back into my SS.

Anyway, most of the time, symptom of stack shift is TV cable not adjusted correctly. Most of the time, that is.....................

OK, got a gauge on it. its only going to 100 psi all throttle positions, @200 psi in reverse,so not the pump or filter.i bought this car, didnt try it all out, was in sad shape! Deleted computer , replaced complete top end cylinders still had hone marks installed L98 heads and holley correcter plate for proper TV cable operation mild summit cam shorty headers flowmasters etc etc... SO the problems in the valvebody

Probably asleep, since you posted in the middle of the night...
I'm not a 200r expert, I just know the TV cable is critical and the non-factory brackets usually have trouble. But if you are sure that its adjusted and functioning perfect, then you probably need to get in touch with a good transmission guy and get the valvebody looked at.

It took me a little while to get used to the speed of the forum. I was used to Facebook where I could ask a question on a group and get 25 answers in 5 minutes but usually 24 of those were wrong and people just flabbing to look like they knew something. Ive ask questions here before and it take a week or more before someone answered but when they did answer it was the correct answer. On here I have found that if people don't know they don't answer, which in my mind is a good thing. Im sure someone will come by at some point and have the answer you are looking for. If not, might be headed to transmission shop.

When we installed the Bowtie Overdrive 200r in a 67 Camaro one of the things they were adamant about was checking pressures to insure the TV was functioning correctly. They have a big install instruction page on their website that tells how to check pressure on the 200 and 700 trans but don't tell what those numbers should be. It was more than 10 years ago we installed that trans. I think back then we checked the pressure and then had to call Bowtie with the numbers.

Here's there instructions: page 15 is pressure checking.
http://bowtieoverdrives.com/Instructions/BOW%20TIE%20OVERDRIVES%20INSTALLATION%20GUIDELINES.pdf

We did initially install an Edel Performer carb on the that engine with a kit to adapt the TV to it. It was problematic. I then built a Qjet with the correct TV linkage on the carb and the trans functioned much better with factory linkage designed for the 200r TV.

This info here is critical to having the 200R TV set up correctly.
http://www.cpttransmission.com/tech_tvcable.htm

Now with a third pedal, clutch, in my SS for almost 20 years I'm a little out of touch with the 200R.

Also you will find it hard to get someone today that is very familiar with the 200, it's almost 35 years ago they were common. But today i still feel they are the ideal trans for a lot of street cars, especially street rods.

Be patient and work through the problem. And don't destroy the trans, rebuilds are very expensive and hard to find locally someone who can do a high performance upgrade/rebuild.

Going non computer generally opens a can of worms rather than resolve problems. Aftermarket quality is mostly worse than OEM. Its one of the many reasons it is advised here to stay with the computer. The TV cable is designed for a factory Qjet and it is not easy to get aftermarket carbs and brackets to operate correctly with the TV cable. Most aftermarket carbs do not perform better than Qjets anyway.

With it not having ccc hooked up would the lock up torque converter be affecting the shift?

First, I hope Chris don't mind me putting up this info. I got this from his book and it's my trans bible. I got this almost 10 years ago, and planning to buy another to see if he found anything else for me to learn.

Anyway, here are some info you should look at. Most, if not all, have TV cable adjustment as possible cause.

Again, start by TV cable. I know you have the corrector, but AFAIK, Holley and corrector don't mix well. I have Eddy carb myself and somewhat satisfied, but not completely. Just changed my valve spring, which was waaaaaaaaaaaay overdue, so maybe I'll tackle that cable adjustment next.
