FIOD 4R70 4R75 [80-UP] Automatic Transmission Bushing Forward Sun Gear E

For FIOD automatic transmissions. When the bushing at the forward sun gear wears down inside an FIOD or 4R70 automatic transmission, shaft support at that location degrades and end play open up, putting stress on surrounding components that were not designed to absorb it. This listing is for the single forward sun gear bushing that addresses that specific wear point, nothing more and nothing less.

The part covers FIOD and 4R70 applications from 1980 forward. If your unit falls in that range and the forward sun gear bushing is the piece you need, this is a straightforward replacement. Because it is a single component and not a kit, there are no clutch discs, seals, gaskets, or Automatic Transmission Filters in the box. Technicians building a full overhaul will need to source those separately.

At REMCO, parts like this one are pulled and packed individually, not shipped out of a pre-assembled multipiece bag. The part is verified against the item record at the time of packing, and the part number reference ships inside the box so there is no guessing when it arrives on the bench.

Before placing the order, confirm the unit code is FIOD or 4R70 and that the vehicle year is 1980 or later. A single bushing ordered for the wrong unit is a delay no rebuild needs. Matching the unit designation first is the fastest way to keep the job on schedule.

• FIOD automatic transmission: this forward sun gear bushing addresses wear at a critical load-bearing point inside the unit, helping restore proper gear support and reduce play that leads to further internal damage.
• This listing is for a single bushing only. It does not include clutch discs, steels, seals, gaskets, Automatic Transmission Filters, or any other components. Review your rebuild parts list carefully before ordering to avoid a wasted trip.
• The forward sun gear position takes constant rotational stress in FIOD and 4R70 units. Replacing the bushing at this specific location is a targeted fix that supports shaft alignment and keeps clearances within spec.
• One forward sun gear bushing, weighing 1 lb as packaged. The part is pulled individually and checked against the item record before the box is sealed, and the part number is included inside.
• Before ordering, confirm your unit is an FIOD or 4R70 and verify the application year falls within the 80-UP range. Matching the unit code first helps avoid fitment errors on a single-piece order.
