Oil Pumps

Remanufactured and new oil pump assemblies — vane, gear and gerotor types, flow-checked before packing.

Quick answer: Every oil pump from TRANSMESUN is flow-checked before packing. Weak pumps mimic valve body faults — before you buy either, a line pressure test tells you which part actually solves your symptoms.

Buyer FAQ

Common questions on oil pumps.

Pump or valve body — which is failing?

No movement in any gear or consistently low line pressure points to the pump or filter starvation; shift-quality faults that change with temperature point to the valve body. A line pressure test before ordering parts is always cheaper than guessing.

Are pumps tested before shipping?

Yes — flow-checked on the bench, like every hydraulic component we sell. The test result ships with the unit.
