Speedmaster PCE693.1004 GM Powerglide Billet Front Oil Pump Ringless Design

The Speedmaster PCE693.1004 is a high-performance billet front oil pump engineered specifically for GM Powerglide automatic transmissions. This advanced pump delivers superior transbrake operation at low RPM, making it ideal for high-performance and racing applications where consistent hydraulic pressure is critical.

Key Features:

• Billet aluminum pump body and stator back for maximum strength and durability
• 20% lighter than stock pump at 11.5 lbs versus 14.4 lbs, reducing rotating mass
• Billet 4140 HTSR steel stator shaft will never spin-out
• Positive stop bushing area with provisions for staking bushing to prevent bushing spin
• Snap ring design to prevent seal blow-out under high pressure conditions
• Lube reliefs machined into outer gear pockets for improved oil flow
• Ringless design requires ringless input shaft (not included)
• Includes oil pump gasket

Speedmaster has developed a process to improve pressure and flow over stock pump assemblies, providing the reliability needed for demanding performance applications. This bolt-in design features precision-machined components that deliver consistent hydraulic pressure for improved shift quality and transbrake performance.
