2004R Pressure Regulator Valve

[turbo6randy]

Looking for a stock pressure regulator valve to fit a 2004R transmission. Someone has replaced my stocker with an aftermarket and I've got to much pressure.

Be more specific. What has been replaced? What is your pressure

After doing a search I found this thread. My pressure valve is the one on the pictured on the right and I have a purple pressure spring that I believe is from TCI. Don't remember my pressure readings but have had a problem with second gear starts.
