FIOD 4R70 4R75 [80-UP] Automatic Transmission Bushing Planet (Rear)

For FIOD automatic transmissions. When the rear planet bushing in an FIOD or 4R70 automatic transmission wears out, shaft movement at that position throws off the whole rotating assembly and sets up conditions for accelerated damage further into the unit. This is a single replacement bushing for that exact location, sized at 1.380 in outside diameter, and it fits the rear planet position on FIOD and 4R70 units covering applications from 1980 forward.

This listing covers one piece. It does not come with seals, gaskets, clutch packs, steels, an Automatic Transmission Filter, or any other rebuild components. If your overhaul calls for additional parts, those need to be sourced separately. Knowing exactly what is and is not included before ordering avoids delays on the bench.

The rear planet bushing on these units carries rotational load continuously during operation. When it wears, you get measurable shaft float that affects clutch apply and can lead to noise, slippage, or internal damage that a fluid service alone will not fix. Swapping the bushing during a rebuild, rather than leaving a worn one in place, keeps the assembly within the tolerances the unit was designed around.

The outside diameter on this bushing is 1.380 in. Before ordering, verify that your unit is an FIOD or 4R70, that the year of the application falls in the 80-UP range, and that the worn bushing you are replacing measures 1.380 in on the outside diameter. A quick check against those three points is the fastest way to confirm fitment. The part number on file is.

• FIOD automatic transmission: restores proper shaft alignment at the rear planet position in FIOD and 4R70 units, preventing premature wear and play that leads to repeat failures.
• This listing is for one bushing only. It does not include any seals, gaskets, clutch discs, steels, Automatic Transmission Filters, or other components. Verify what else your job needs before ordering.
• The rear planet bushing on these units takes direct rotational load. Replacing it as part of any overhaul keeps tolerances within spec and avoids comebacks tied to sloppy planet support.
• One rear planet bushing, 1.380 in outside diameter, weighing 1 lb. Pulled individually from stock and verified against the part number before it ships.
• Confirm your unit is an FIOD or 4R70, that the application year falls within the 80-UP range, and that the rear planet bushing measures 1.380 in OD before placing your order.
