GM Gen. 2 6T70, 6T75 and 6T80 transmissions may exhibit multiple line pressure and converter-related problems due to excess wear in the main pressure regulator bore. Wear at the balance spool end allows critical fluid loss, resulting in excess line pressure, harsh shifts and overheating due to reduced cooler/converter flow. Wear at the outboard spool robs converter feed pressure and lowers line pressure, resulting in soft shifts and burnt clutches.
Reconditioning the bore and installing Sonnax oversized pressure regulator valve kit 124740-60K will restore hydraulic integrity for proper line pressure control in all ranges.

Oversized pressure regulator valve and matched spring restore OE function
Extended valve land for better sealing
Hardcoat anodized aluminum valve combats premature wear
