Full set of steel separator plates for a GM 6L80, 6L80E, 6L90 or 6L90E rebuild so new frictions seat flat instead of on burnt, dished steels.
When a 6L80 comes apart after slipping, flaring on the 2-3 or losing reverse, the frictions get all the attention, but the steels are usually just as cooked. This is a complete steel separator plate module for the GM 6L80, 6L80E, 6L90 and 6L90E six-speed, 2006 and up, superseding GM 195753A, 195753B and 195753BX. It gives a rebuilder of a Silverado, Sierra, Tahoe, Yukon, Escalade, Camaro, CTS or Express van a full set of flat, true steels instead of reusing heat-damaged plates.
Each clutch pack in the 6L80 alternates friction plates with steel plates. The 1-2-3-4, 3-5-R, 4-5-6, 2-6 and low/reverse clutches are all applied by hydraulic pistons and released by springs, and every shift is one clutch letting go while another clamps. The steels are the hard surface the friction material grips. If a steel is warped, dished or glazed, the pack only contacts in a ring at the edge, so it slips, makes heat in a small area, and burns new frictions quickly. Because the 6L80 has no one-way clutch to smooth out most shifts, a pack that grabs unevenly shows up as harsh or flared shifts and codes for gear ratio errors.
Steels are bought during a teardown, not before. Lay each steel on a flat surface plate or a piece of glass and check for rocking, then look for heat discoloration and scoring you can catch with a fingernail. Measure thickness against the plate you are replacing. Also make sure the failure was not caused by something upstream, such as low mainline pressure or a leaking drum seal, or new plates will burn the same way. Our 6L80 common problems guide covers the clutch failures that show up most, and the Camaro shift problems guide goes deep on the 2-3 flare and pressure testing.
The listing covers the 6L80, 6L80E, 6L90 and 6L90E from 2006 on, including Silverado 1500 2008-2022, Silverado 2500HD 2007-2022, Tahoe 2008-2020, Escalade and Escalade ESV 2006-2018, Camaro 2009-2015, CTS 2007-2015, CTS-V 2008-2015, Express 1500-4500 vans 2009-2021, Hummer H3 and H3T, and XLR and XLR-V 2006-2009. Six-speed units only. The 6L90 uses a longer case and heavier internals than the 6L80, so do not assume every pack matches between the two; count the steels you remove from each drum and match them before final assembly.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is a complete steel separator plate module meant to cover the clutch stacks in the 6L80 family. Count the steels you remove from each drum and match the kit before final assembly, especially on a 6L90.
The listing covers the 6L80, 6L80E, 6L90 and 6L90E from 2006 on. The 6L90 has heavier internals, so verify the plate count per pack against what you removed.
Only if they are flat, the right thickness, and free of heat discoloration and scoring. Steels that rock on a flat surface or show blue spots will glaze new frictions quickly.
GM 195753A, 195753B and 195753BX.
Fill with Dexron VI, set the level at operating temperature, and run the transmission fast learn so the control module relearns clutch fill times.
