6T30 Clutch Module 2016-2019, new and ready to install. Fits the 6T30. Ships fast from the USA.
Late-model 6T30 transaxles are small, light units, and once their clutch linings wear thin they let you know with a slip on the way up a ramp, a flare into 3rd or 5th, or a pan full of dark, burnt-smelling fluid. This listing is a Gen 3 friction clutch module for 6T30 transmissions built from 2016 through 2019, also listed for the closely related 6T35. It is the set of friction plates you install once the unit is apart and the old linings are glazed, flaking or worn down to the core.
GM's 6T30 is the lightest member of the family that includes the 6T40, 6T45 and 6T50. It uses the same five-clutch layout: low and reverse, 1-2-3-4, 2-6, 3-5-reverse and 4-5-6, with two clutches applied in every gear and one released and another applied on each shift. Each clutch is a stack of lined friction plates between steel plates, squeezed by a hydraulic piston. The friction lining is what grips. When it wears, the stack takes longer to lock, the control module adds pressure to compensate, and when it has no more room you feel the slip. On a small-displacement car the engine flare can be subtle at first, so many owners first notice it as poor acceleration or rising rpm on the highway.
The 6T30 is sensitive to fluid level, and a low unit will slip on frictions that are still good. Set the level hot through the check plug, following the procedure ATRA published for the 6T35, 6T40 and 6T50, then read stored codes. If the slip is mostly at engagement, work through our delayed engagement guide; if shifts are harsh or erratic as well as slipping, the valve body symptoms guide covers the control-side faults to rule out first. GM's PI0670A also warns against air checking the 3-5-reverse clutch through the case, so final confirmation comes on the bench.
This module is listed for Gen 3 6T30 and 6T35 transmissions from 2016 to 2019. It is not the right set for an earlier unit: 2009-2013 Gen 1 builds use the 2009-2013 6T30 clutch module, and Gen 2 builds have their own 2013-2018 module. Because the model years overlap between designs, check the transmission RPO on the glovebox or door sticker and compare each removed plate's count, thickness and tooth profile with the new ones. Send us your year and VIN if anything does not match. If the drum splines are notched or the housing is scored, the 6T30 clutch drum is the matching hard part.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for Gen 3 units from 2016 to 2019, so a 2014 or 2015 is more likely a Gen 2 transmission that takes the 2013-2018 module. Send us your VIN and we will confirm.
Yes, the module is listed for both the Gen 3 6T30 and the 6T35. Match the plates you remove against the new set before installing.
It is a friction clutch module for the transmission rather than a single clutch pack. Count and compare the plates as you unpack them so each clutch gets the right ones.
An overhaul kit with seals and gaskets, a new filter, and any steels, drums or wave plates that show heat damage or cracks.
DEXRON VI, with the level set hot at the check plug. Clear the adaptive values after the rebuild and complete a relearn so the module learns the new clutch packs.
