Master rebuild kit for the GM 6L80 and 6L90 six-speed: clutch plates, pan gaskets, valve body gaskets, seals and sealing rings. Replaces 195903XLS.
This kit is for the 6L80 or 6L90 that has already told you it needs to come apart: a 2-3 shift that flares, reverse that engages late or not at all, a converter that shudders, or a pan with friction material on the magnet. It replaces kit number 195903XLS and is listed for the 2008-2016 Corvette 6.2L and the 2009-2010 GMC Savana 3500 6.0L, and it fits the same 6L80E/6L90E unit used behind the V8 in GM full-size trucks and SUVs. What is in the box, going by the kit photo: several sets of friction plates, the cork pan gasket and case gasket, three valve body spacer plate gaskets, the pump gasket, the front and rear lip seals, bonded seals, a bag of O-rings and the sealing rings. There are no steel plates, pistons or filter in this kit, so plan for those separately.
The 6L80 makes six forward speeds from five clutches: 1-2-3-4, 3-5-R, 4-5-6, 2-6 and low/reverse. Each gear is two of those applied at once, which means one burned pack ruins more than one gear. A slipping 3-5-R clutch, for example, hurts third, fifth and reverse together. The frictions in this kit replace the lining in every pack, and the sealing rings and lip seals restore the oil circuits that feed the clutch pistons through the turbine shaft and the stator support. The three spacer plate gaskets matter because they seal the passages between the valve body, the spacer plate and the case; a torn or compressed one lets solenoid-controlled pressure bleed off before it reaches the clutch it is supposed to apply.
Not every 6L80 complaint is a clutch pack. A cold 2-3 flare can be the air-in-the-3-5-R condition GM addressed with a Reverse-before-Drive purge, and a worn actuator feed limit valve bore in the valve body can starve every solenoid and mimic clutch failure. Start with codes and a pressure test at the line pressure port, then check the adapts and the fluid. If the fluid is burnt and the pan has clutch debris, the unit needs a teardown. Our guide 6L80 common problems and fixes walks through the seven failures in order, and 6L80 pump failure symptoms covers the pump side, which should be inspected while the case is apart.
The listing names the 2008-2016 Corvette 6.2L (6L80) and the 2009-2010 Savana 3500 6.0L (6L90). The 6L90 uses a longer case, a different output shaft and heavier internals than the 6L80, so before you order, read the transmission ID tag on the case and confirm whether you have an MYC (6L80) or MYD (6L90), and count the plates in each pack on teardown against the kit. If you are unsure, send us your year and VIN before ordering. You can browse every part we carry for this unit on the 6L80 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The kit carries friction plates, gaskets, three valve body spacer gaskets, the pump gasket, seals, O-rings and sealing rings. Steel plates, pistons and the filter are not in the box, so buy a steel kit if yours are blued or warped and a new filter with its neck seal.
It is listed for both the 6L80 and the 6L90, including the 2009-2010 Savana 3500 6.0L. The 6L90 has a longer case and heavier internals, so check the case tag (MYC or MYD) and compare plate counts per pack on teardown before assembly.
DEXRON VI only. Soak the frictions in it before assembly, and fill to the check plug at operating temperature, since the 6L80 has no dipstick.
It is the kit number this master kit cross-references. Use it to compare against a parts book or the kit you are replacing, but confirm fitment by transmission tag, not by kit number alone.
Yes. Reset the transmission adapts and run the fast learn with a capable scan tool. New frictions change clutch fill times, and stored adapts from the worn unit will make shifts harsh or flared until it relearns.
