6L50 Clutch Drum 2014

Looking for the rear clutch support housing for a 6L50? This listing is the 2-6 and low/reverse support clutch drum from a 2014 Chevrolet Camaro with the 3.6L V6. It is an aluminum assembly about 5.555 in. tall. It comes loaded with the five-plate low/reverse pack, the 2-6 clutch, and the low sprag assembly. It is the part to look at when a Camaro, CTS or other 6L50 car loses second and sixth gear, has no reverse, or will not hold in first.

What the 2-6 and low/reverse support does in a 6L50

Unlike the rotating drums at the front of the 6L50, this support houses the holding clutches. These clutches stop part of the gear train so the planetary sets can make a ratio. According to the Sonnax 6L45-6L90 application chart, the 2-6 clutch is applied in second and sixth gear. The low/reverse clutch is applied in Park, Reverse and manual first, where it gives engine braking. In Drive first, the low sprag does the holding instead. One assembly therefore controls second, sixth, reverse and the launch from a stop. A cracked support, a leaking piston or a worn sprag race takes several of those ranges out at once.

Symptoms of a failing 2-6 / low-reverse support

• Flare or slip on the 1-2 shift, or a 5-6 shift that slips or never happens
• Delayed, soft or no reverse while the forward gears still pull
• No movement or a slip off the line in Drive, from a sprag that freewheels both ways
• No engine braking in manual first
• Burnt low/reverse frictions or broken sprag elements found in the pan or at teardown

How to confirm before buying

Use the gear pattern. Second and sixth fail together on a bad 2-6 circuit, while reverse plus manual low points to the low/reverse side. A Drive-only launch problem with good reverse leans toward the sprag. Do not condemn the support without checking the hydraulics first. The 2-6 and low/reverse regulator valves in the valve body wear, and the Sonnax vacuum test guide lists burnt 2-6 clutches and shift concerns in 2nd and 6th among the symptoms of a worn 2-6 regulator bore. Run a line pressure check and the codes covered in our 6L45/6L50 limp mode guide. Our flare vs. slip guide explains how to tell a timing problem from a worn clutch.

Fitment

This support came out of a 2014 Camaro 3.6L V6 with the 6L50. Other 6L50 applications and model years can differ in the support casting, the sprag and the plate count. Measure the height, count the plates, and compare the casting numbers with your original before ordering. If in doubt, send your year and VIN. See every 6L50 part on our 6L50 parts page.

Install notes

• Check that the sprag freewheels in one direction and locks in the other before installation, and inspect the races for brinelling.
• The installed frictions and steels are used. On a full overhaul, replace them and the piston seals, then set the 2-6 and low/reverse clearances to spec.
• Air-check both pistons through their feed holes once the support is in the case.
• If the front drums are also worn, the 6L50 1-2-3-4 and 3-5-R drum and the 6L50 4-5-6 input drum are listed separately.
• Refill with Dexron VI, check the level hot per the GM procedure, then perform the fast learn before road testing.

Which clutches are in this drum?

The 2-6 clutch and the low/reverse clutch, with five low/reverse frictions installed, plus the low sprag assembly.

What does it fit?

It came from a 2014 Chevrolet Camaro with the 3.6L V6 and 6L50. For other vehicles, match the casting numbers, height (about 5.555 in.) and plate count to your original, or send us your VIN.

Why do I have no 2nd and no 6th?

Both gears use the 2-6 clutch, so a slipping 2-6 pack, a leaking piston in this support, or a worn 2-6 regulator valve in the valve body will take out both gears together.

Does it come with the low sprag?

Yes. The low sprag assembly is included, which holds first gear in Drive. Spin-check it before installing.

What fluid and relearn are needed?

Dexron VI ATF. After installation, reset the adaptive values and run the GM fast learn with a scan tool.
