When the front case bore on a 4R100, C6 or E4OD unit shows wear, shaft movement increases and fluid control at that point breaks down; replacing the front case bushing is the direct fix for that condition. This is a single hardened bushing with three machined grooves, built specifically for that front bore position on these three transmission families.
The 3-groove design is not cosmetic. Those grooves allow transmission fluid to spread across the bushing surface and reach the shaft journal continuously during operation, which matters in a location that sees sustained rotational load. A smooth-bore replacement in this position does not serve the same function, so matching the groove count to the stock spec is part of getting the repair right.
Hardened construction means the material has been processed to resist the surface wear that causes these bushings to fail in the first place. Softer material in this location wears faster, which shortens the interval before the same problem returns.
This listing covers a single piece. There are no seals, gaskets, clutch components, or other parts included. If your rebuild requires additional bushings or a broader overhaul set, those would need to be sourced separately.
REMCO has worked in automatic transmission parts since 1991. Each piece is pulled individually and checked against the part record before it goes out. A part list is included in the box.
Before placing the order, check the transmission identification tag on the unit and confirm it reads 4R100, C6 or E4OD. Also verify the vehicle model year falls within the [66-UP] range this bushing is listed for. Application fit depends on the unit code, not on the vehicle make or model.
- Front case bore wear on 4R100, C6 and E4OD units leads to shaft instability and fluid loss; this hardened 3-groove bushing addresses that specific failure point.
- This listing is for a single bushing only. It does not include any seals, gaskets, clutch packs, steels, bands, or any other components. Verify what your job requires before ordering.
- Three lubrication grooves machined into the bushing surface help distribute fluid around the shaft journal, reducing dry contact between moving surfaces during operation.
- One hardened front case bushing with 3-groove design. Unit weight: 1 lb. Pulled individually from stock and verified against the part record before shipping.
- Before ordering, confirm the transmission code on the unit tag matches 4R100, C6 or E4OD and verify the model year falls within the [66-UP] range this bushing covers.
