Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits

Required tool kit F-102741-TL8 is no longer in production. Check with your distributor for availability.
Hyundai/Kia A6GF1, A6LF1/2/3 and A6MF1/2 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 high 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 102741-08K restore hydraulic integrity for proper line pressure control and improved shifting in all ranges.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.

Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
