FS501970XA Automatic Transmission Oil Pump Remanufactured 5F27E FN5R Pump for Mazda 3 Mazda 5 Replacement Parts

This is remanufactured 5F27E FN5R automatic transmission oil pump assembly, OE reference number FS501970XA, specially matched for Mazda 3 and Mazda 5 models equipped with 5F27E FN5R 5-speed automatic transmission.

Transmission oil pump is the core hydraulic power source of the automatic gearbox. It continuously provides stable ATF pressure for clutches, valve body and internal lubrication. Worn pump gears, loose clearances or aging sealing rings will cause insufficient oil pressure, shifting slip, delayed gear engagement, gearbox overheat and fault light alert. Our remanufactured pump undergoes full disassembly, vulnerable parts replacement and hydraulic bench testing to restore original hydraulic output performance.

Warm Reminder: Confirm your vehicle model and original gearbox type 5F27E FN5R before placing orders to avoid mismatching.

Standard Remanufacturing Process
Fully disassemble old oil pump, ultrasonic clean pump housing and gear group; replace worn gears, sealing rings, bearings and spring accessories with brand-new standard parts, recover OEM internal gap parameters.

100% Hydraulic Bench Test
Every finished pump is loaded on professional test bench to simulate real vehicle rotation speed, test output flow and oil pressure stability, eliminate insufficient pressure and internal leakage risks.

1:1 OEM Direct Installation
Manufactured strictly per original drawing, consistent mounting hole, oil inlet/outlet interface and outline with original pump, no cutting or modification needed for on-board replacement.

Fix Typical Transmission Faults
Effectively repair shifting slip, slow gear engagement, gearbox abnormal noise, overheat protection and fault codes triggered by failed original oil pump.
