Key Features of Rebuilt 66RFE Pumps

- Seal Type: Often comes as a “Seal on Front Cover Plate” style, which fits both 66RFE and many 45/545RFE housings.
- Remanufacturing: Typically includes fully disassembled, cleaned, and inspected units with new pump bushings and updated parts.
- Common Issues Addressed: Rebuilt units often replace the stock TCC limit valve to prevent premature converter failure.
Note: Some listings specifically exclude the front seal in the pump assembly, requiring it to be purchased separately or transferred from the old unit.
