Gen 1 production covers roughly the 2008-2011 model years, which in the US market means: 2008-2011 Chevrolet Malibu 2.4L I4; 2009 Saturn Aura 2.4L I4; 2009-2010 Pontiac G6 2.4L I4; 2010-2011 Chevrolet Equinox 2.4L I4 and 2010-2011 GMC Terrain 2.4L I4 (both 6T45); 2011 Chevrolet Cruze 1.4L turbo (LUJ) and 1.8L (LUW); 2011 Buick Regal 2.4L I4; and 2011 Buick LaCrosse 2.4L I4.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e There are two separate traps, and the second one catches even experienced rebuilders. TRAP 1 — Gen 1 vs Gen 2, the ring count. Before ordering, count the sealing rings on the hub (the \"ring tower\") of the drum you pulled out. This drum has FOUR rings. The Gen 2 drum has only THREE — GM's own bulletin PI0604C describes the change as \"Removal of one 3-5-Reverse and 4-5-6 Clutch Fluid Seal Ring.\" Cross-check two more ways: count your 4-5-6 friction plates (Gen 1 uses 4 frictions plus a wave plate; Gen 2 uses 5 frictions and no wave plate), and count the holes in the hub area where the support rides (this Gen 1 drum has 10 smaller holes; the Gen 2 version has 9 larger ones). If you put a 3-ring Gen 2 drum into a Gen 1 unit, the missing fourth ring and the missing fluid-dam inner seal mean the compensator regulator circuit no longer regulates and sits wide open — you get a low-pressure complaint, typically falling out of gear at a stop.\u003c\/p\u003e\n\u003cp\u003eBefore you order: confirm your transmission code and casting\/part numbers.
