Not sure, numbers check out to OG from 1985 Olds B/D was behind 304 Y with 2.73 rear end gear. Could be delta 88 or 98, cutlass Cruiser wagon, etc.

Even without S hook connected it was very very difficult to move the manual valve link into the valve body, I removed it to make sure there wasn’t an obstruction but didn’t see anything in the bore. Hoped it was just needing atf, or pressure from pump, but no luck.

Frustration! I got it all back together, but now it won’t get out of park. The Manual valve link, is frozen in the valve body, any guesses? And pressure in park was lower now than before, I’m about ready to give up.

Broken accumulator spring on left, replacement on right. I have to believe this wasn’t helping my 1-2 shifting.

I’m running stock internals as far as I know except for TransGo Hi-Performance Booster Valve kit .500. And light blue spring from Shift Technology Products 200-4R kit, I’m guessing it’s time to install the other springs from this kit.

Ok folks here are my pressures 1000 RPM engine temp 190 degree + Connected. Then Pulled fully Park. 100. 170 Rev. 210-240. 210 Neutral. 100...

Steve, thanks for your input, I feel I have the TV properly set up. I’m using the BTO plate and cable for my set up. Might be much deeper than I feel comfortable with transmission surgery. TexasT I am running a stock opening on top filter, and 1quart over, my shudder is at such a slow speed...

Drum glazed and band burnt equals rebuild time I’m guessing?

https://streettechmag.com/2015/04/01/2004r-swap/#prettyPhoto In doing more research I came across an article talking about replacing the TV spring with a Longer TV pressure spring to be used with their BTO system (I didn’t get this) but do have a Shift HP kit that probably does. Says that helps...

Steve V, I’m getting a substantial full car shake shudder at low speed maybe 10-15mph? It’s always When auto shifting between 1-2 gear and seems to slightly flair at end while finishing making that shift, all this while driving with low/normal throttle pressure speeds in my neighborhood. I’ve...

Speedometer is connected, I’m not running a computer with the 200-4R so don’t think that’s it. Does anyone know is a shudder typically caused by too high line pressure OT too low pressure? Am I crazy thinking the torque converter could be bad?

Thank you I did replace the TCC solenoid thinking along those lines too. If line pressure is too high, or too low wound that cause the shudder? Or is that also a symptom of burnt clutches/ bands?

I will retest and get the pressure measures, I know that proper TV set up is important, but in theory would loosening (adjusting toward carb) decrease tension on cable and as a result reduce pressure?

I will have to go back and look at my notes, initially they were lower than the “standard ranges” I have researched, but with larger .500 booster valve they were better. I can recheck them and see, are you working on a theory Jim?

No computer controlling transmission or diagnostic code reader, I’m totally old school

Good morning guys/gals, I’m new to the 200-4R world and looking for help. I purchased a 2004R that was originally in a 1985 Olds OG 307. It had been sitting for 2+ years in guys garage and has unknown mileage. Dropped the pan and was not concerned with any smell or any large build up of...
