OE end plugs are designed to prevent critical pressure loss by capping the bore while also functioning as a spring or valve stop. Repetitive spring motion, valve impact and fluid pressure variations cause wear between the end plug and bore mating surface, allowing vital pressure to escape the circuit.
GM 9T45/50/60/65 valve body and pump have end plugs at various bores that are susceptible to the wear conditions described above. When pressure drops due to plug deterioration, assorted shift concerns can arise and burnt clutches often result in the affected circuit. Put an end to leaks, restore hydraulic integrity and renew shift operation by installing Sonnax O-ringed end plug kit 184740-03K.

Minimal end-plug-to-bore clearance with added O-ring for positive seal
Prevents loss of critical pressure
Reduces or eliminates leakage in eroded OE bores
