Replacing worn or cut sealing rings at the input shaft and pump bores is one of the first steps when diagnosing pressure loss in an automatic transmission, and having the correct Teflon rings on hand makes the difference between a repair that holds and one that comes back. These rings are selected specifically for the 4L60E, 4L65E, 4L70E, and 4L65 family, covering units produced from 1994 through 2016, so they match the bore dimensions and groove profiles found in those units.
Teflon is the material of choice for this application because it resists the heat that builds up during normal automatic transmission operation without swelling, shrinking, or taking a permanent set the way softer materials can. A ring that keeps its shape holds a repeatable seal in the bore, which matters for circuits where pressure is critical to clutch apply and release timing.
This is a single-line item covering the input shaft and pump sealing rings. It does not include friction plates, steels, an Automatic Transmission Filter, a gasket set, a band, or any other rebuild component. If your job calls for a complete overhaul, check separately for those parts before placing this order. Mixing up what a listing includes is one of the most common reasons for returns on transmission parts, so read the contents carefully.
The item weighs 0.2 lb. At REMCO, parts like these are pulled and packed individually against a piece list, not shipped out of a pre-made bulk bag, which is how the count stays accurate order to order. The piece list travels with the shipment so you can verify contents on arrival.
Confirm your transmission identification code before ordering. The 4L60E, 4L65E, 4L70E, and 4L65 share a family but have enough variation across model years that using the wrong parts creates problems at assembly. If you are unsure of your code, check the unit tag or the vehicle build sheet before purchasing.
