This is not a rebuild or just a partial replacement – it’s 100% brand new and complete! The PGP1 has been designed from scratch to strengthen and update the Powerglide pump for your racing applications.
Larger pump gears for more volume and pressure at low RPM.
Extra volume to prevent rocking or backing up when transbrake is applied
Stiffer castings with ribs to prevent flexing and pressure loss at high line pressure
High strength cast iron for maximum rigidity and minimum distortion at high temperatures
Custom, high strength stator support shaft to handle high horse power
Extra clamping bolts (7 total) to hold pump halves together at high pressure
Redesigned oil pathways to increase flow to converter and cooler
High clutch drum bushing pressure feed
Factory machined for roller thrust bearing
