Pressure Regulator Valve Kit - 104520-14KRecover hydraulic control and renew line pressure performance by installing Sonnax pressure regulator valve kit 104520-14K. Fits GM 6L45, 6L50, 6L80, 6L90www.sonnax.com
The Sonnax imidized checkballs are part number 10000-08. I saw them in various places on the internet for around $15 for a bag of 8-10.
I purchased a GM 24236934 Plate Kit, Control Solenoid Valve Filter to get the various seals and such for the valve body, and the filter plate for the TECHM. As well, there was a bag of OEM check balls in it. This kit is around $38 on the internet.
