Restoring hydraulic integrity in a 6L80E or 6L90E starts with the sealing rings, and this set is sourced specifically for those units built from 2006 onward. What sets this article apart from a generic ring assortment is that it is listed and verified against the 6L80E application record, so the rings you receive correspond to what that transmission actually requires rather than a catch-all ring pack.The 6L80E and 6L90E are six-speed automatic transmission units found across a wide range of rear-wheel and four-wheel-drive platforms produced from 2006 through current production. Over time, the sealing rings that regulate fluid between shafts, clutch drums, and hydraulic circuits develop flat spots, cracks, or dimensional wear. When that happens, pressure drops behind the ring and the transmission exhibits soft engagements, delayed shifts, or full slippage in one or more ranges. Replacing the rings is a fundamental step in any rebuild of these units.This is a single article, not a master overhaul kit. It does not include friction clutches, steel reaction plates, an Automatic Transmission Filter, a gasket set, or a band. Technicians who need those parts should source them under their respective listings. This set is the right choice when the diagnosis points specifically to ring wear or when completing a repair where the rings were not included in a previously purchased kit.At REMCO, parts are assembled into each order individually at the facility rather than shipped from a prepackaged box. The box includes a parts record so the technician can verify contents on arrival. REMCO has worked in automatic transmission parts since 1991.Weight is 0.65 lb. Confirm the unit identification code and build year before ordering. This sealing ring set addresses internal fluid bypass in 6L80E and 6L90E units, helping restore hydraulic pressure and prevent slipping caused by worn or cracked rings. This listing does NOT include friction discs, steel plates, Automatic Transmission Filter, gaskets, or bands. If your repair requires those components, check fitment and purchase them separately before ordering. Sealing rings are the component most often overlooked in a transmission overhaul, yet a failed ring drops line pressure across multiple circuits simultaneously, making this a high-impact part for its size. Contents: one sealing ring set for 6L80E and 6L90E applications, 0.65 lb total weight. Packed at the REMCO facility and verified against the part record before shipping. Before ordering, confirm the transmission code stamped on the unit matches 6L80E, 6L90E, or 6L80 and that the build date falls within the 2006-and-later range this part covers.
