Worn or cracked sealing rings inside a 4R70W, 4R75W or 4R70 automatic transmission allow fluid to bypass circuits that depend on sealed pressure, producing soft shifts, delayed engagement or pressure-related codes. These sealing rings are sized specifically for those three transmission models as built from 1994 through 2003, so they address that failure point directly without requiring you to buy components you do not need for this part of the job.
What separates this listing from a generic ring assortment is the application focus. The rings here are selected for 4R70W, 4R75W and 4R70 geometry. REMCO has been working with automatic transmission parts since 1991, and each order is assembled piece by piece at the facility rather than arriving as a prepackaged unit from a third party. A printed parts list is included in the box so the technician receiving the order can verify contents before the transmission is opened.
This listing covers sealing rings only. It does not include clutch friction discs, steel reaction plates, an Automatic Transmission Filter, a band, gaskets or any other rebuild components. If your rebuild requires those parts, they need to be sourced separately. Confirm that before placing this order so your teardown is not waiting on a second shipment.
The assembled weight is 0.2 lb. Before ordering, check the identification tag or case casting on the unit and confirm the code reads 4R70W, 4R75W or 4R70, and that the build year falls between 1994 and 2003. Units outside that range may use different ring dimensions and are not covered by this listing.
- Sealing rings sized for 4R70W, 4R75W and 4R70 automatic transmission units built between 1994 and 2003, addressing internal fluid bypass caused by worn or cracked rings.
- This listing covers sealing rings only. It does not include clutch discs, steel plates, Automatic Transmission Filter, band, gaskets or any other rebuild components. Review your parts list before purchasing.
- Each ring is pulled individually and checked against the packing list before the box is sealed. A printed parts list ships inside every box, so you can verify contents on arrival.
- Sealing rings for 4R70W, 4R75W and 4R70 applications. Total shipping weight is 0.2 lb, reflecting the exact ring count for this application. No filler parts included.
- Before ordering, confirm the transmission code stamped on your unit matches 4R70W, 4R75W or 4R70, and verify the build year falls within the 1994 to 2003 range covered here.
