About this product

If your 6T30-equipped Chevrolet or Buick slips coming into 3rd or 5th, flares between gears, or smells burnt on the dipstick plug, the clutch frictions are usually where the teardown ends up. This is a new friction clutch module for the Gen 2 6T30, the 2013-2018 version of GM's smallest six-speed front-drive transaxle. It is the plate set a rebuilder installs once the unit is apart and the old frictions are glazed, flaking or worn thin, so the clutches can hold torque again without slipping.

What the clutch module does in a 6T30

The 6T30 makes all six forward gears and reverse with five clutches: low and reverse, 1-2-3-4, 2-6, 3-5-reverse and 4-5-6. Two of them hold in every gear, and the valve body swaps one for another on each shift. Every one of those clutches is a stack of lined friction plates interleaved with steel plates. When the lining wears or burns, the stack can no longer clamp hard enough for the pressure the control module commands, and the transmission slips, flares or sets a ratio code. Replacing the frictions as a matched set restores the clamping surface across all of the clutches instead of fixing one pack and leaving the rest tired.

Symptoms of worn clutch frictions

How to confirm it before you buy

Clutch wear is the last answer, not the first. Set the fluid level hot through the check plug, because low fluid alone causes slips on these units, and read stored codes. A pressure control or solenoid fault can produce the same slips, so read our 6T40 family solenoid symptoms guide and the common problems and fixes guide before pulling the unit. GM's PI0670A is blunt about the 3-5-reverse clutch: do not trust an air check through the case, and inspect the housing and piston on the bench. If the unit is coming apart anyway and the pan shows lining debris, a full friction set is the right purchase.

Fitment: 2013-2018 Gen 2 6T30

This module is listed for 6T30 transmissions built for 2013-2018, which GM calls Gen 2 (2nd design in the parts catalog). GM's PI0604C states every 2013 vehicle it covers uses the Gen 2 transmission, and it lists revised identification markings on the friction plate assemblies for the low and reverse, 1-2-3-4, 2-6 and 3-5-reverse clutches. In practice that means you should lay the old frictions next to the new ones and match count, diameter and tooth pattern before anything goes in the case. Earlier units have their own 2009-2013 6T30 clutch module, and later builds can compare the 2016-2019 version. Not sure which one you have? Send us your year and VIN and we will match it. If the teardown shows the seals are also finished, the 6T30 overhaul kit covers gaskets and seals; match its years to your build.

6T30 Clutch Module 2013-2018: common questions

Does this fit a 2012 Sonic or Cruze with the 1.8L?

Probably not. GM's PI0604C lists the 2012 Cruze and Sonic with the 1.8L as staying on the Gen 1 design, and this module is listed for 2013-2018 Gen 2 units. Look at the 2009-2013 module, or send us your VIN and we will check.

Is this a single clutch or a full set of frictions?

It is sold as a friction clutch module for the 6T30, a set of friction plates rather than one clutch. Before installing, match the plate count, size and teeth against the plates you remove.

What else should I replace with the frictions?

Plan on piston seals or bonded pistons, a filter and a full gasket and seal set, plus any steels or drums that show heat damage or worn splines.

My 6T30 slips into 3rd and 5th with P0776. Is it the clutches?

It can be, but GM's PI0670A says to inspect the valve body, pump, 3-5-reverse housing and piston on the bench before blaming the control module. Burnt frictions are confirmed during that teardown.

What fluid does the 6T30 use, and do I need to relearn?

DEXRON VI, with the level set hot at the check plug. After new frictions go in, clear the adaptive values and complete a relearn so the shift timing matches the new clutch packs.
