About this product

This is a used OEM GM 1-2-3-4 and 3-5-Reverse clutch drum for the 6L50, removed from a good transmission in a 2012 Chevrolet Camaro with the 3.6L V6 at 54,000 miles. It comes loaded, as pictured. If your 6L50 slips in first through fifth, has a soft or missing reverse, or you found a scored or cracked drum during a rebuild, this is the housing that holds the two clutch packs doing most of the work in that range.

What the 1-2-3-4 and 3-5-R drum does in a 6L50

The 6L50 is GM's 6-speed rear-wheel-drive automatic, the heavier-duty version of the 6L45. Its gear changes come from five clutches and a low sprag. Per the Sonnax application chart for the 6L45-6L90 family, the 1-2-3-4 clutch is on in first, second, third and fourth. The 3-5-Reverse clutch is on in reverse, third and fifth. That makes this drum busy in every forward gear except sixth, and in reverse too. In third gear both of its packs are applied together. A leaking piston seal, worn sealing ring lands or a cracked drum shows up as slip in exactly those ranges.

Symptoms of a failing 1-2-3-4 / 3-5-R drum

How to confirm it before you buy

Several cheaper faults cause the same "no forward, slips moving forward" complaint. Gears Magazine documents the number 1 check ball in the upper valve body wearing down from .250 in. to .180 in. or smaller. It sits in the 1-2-3-4 clutch feed circuit, and once it shrinks it can stick in or blow through the spacer plate. A failed low one-way clutch, or a solenoid or TEHCM fault, can also look like a drum failure. Pull the valve body and check that ball first. Then do a pressure test, and follow our 6L45/6L50 limp mode guide for the codes. If the pressure is right and the clutches still slip, air-check the 1-2-3-4 and 3-5-R pistons with the drum in the case. Our 3-5-R clutch failure write-up covers how that circuit fails in the bigger 6L80 family, and the same logic applies here.

Fitment

This drum came out of a 2012 Camaro 3.6L V6 with the 6L50. GM also used the 6L50 in other Camaro V6 model years and in Cadillac applications, and internal parts changed over the production run. Before ordering, compare the drum's casting numbers, spline count, overall height and the number of plates in each pack with your old drum. If you are not sure, send your year and VIN and we will check it. Other 6L50 parts are on the 6L50 parts page.

6L50 Clutch Drum 2012: common questions

Which clutches does this drum hold?

The 1-2-3-4 clutch and the 3-5-Reverse clutch. Together they are used in first through fifth gear and in reverse, so a bad drum often shows up as slip in several gears at once.

What vehicle did this drum come from?

A 2012 Chevrolet Camaro with the 3.6L V6 and 6L50 automatic, at 54,000 miles. Match the castings and spline count to your drum if your vehicle is different.

Is it complete with clutches?

Yes, it comes loaded as shown. For a proper rebuild we still recommend fresh frictions, steels and seals, because the installed plates are used.

My 6L50 has no forward. Is it this drum?

Possibly, but check the number 1 check ball in the upper valve body and the low one-way clutch first. Both cause the same no forward complaint and cost less to fix.

What fluid and relearn does it need?

Dexron VI. After any internal repair, clear the adaptive values and run the GM fast learn with a capable scan tool.
