A: Yes this bundle saves you money vs. purchasing the TP3018 fuel filter and 29539579 transmission filter individually. Q: Can I use this on a 2006 LBZ? A: Yes both filters are correct for all 2001-2016 Duramax engines (LB7, LLY, LBZ, LMM, LML). The LBZ uses the same M36 x 1.5 fuel filter thread and the same transmission filter mount as later generations. Q: Should I change both filters at the same time? A: Not necessarily the fuel filter interval (15,000 miles) is roughly double the transmission service interval (5,000-7,500 miles). Many owners buy this combo to have both filters on the shelf, then change the transmission filter at every transmission service and the fuel filter every other transmission service. Q: What oil do you recommend for Duramax? A: This transmission filter is compatible with all diesel oils conventional 15W-40, synthetic 5W-40, and synthetic blends. For most Duramax engines, 15W-40 conventional (summer) or 5W-40 synthetic (winter) is recommended. The LML and L5P generations specifically call for 15W-40 CK-4 or FA-4 specification oil. Q: Will this fit trucks with the 1R-0750 filter head conversion? A: The transmission filter fits regardless. The TP3018 fuel filter fits the standard 12642623 filter housing . If you've converted to the 1R-0750 CAT filter head, you'll need a CAT 1R-0750 filter element instead. See our 12642623 + 1R-0750 conversion kit . Q: Is this combo cheaper than buying filters separately? A: Yes bundling the TP3018 fuel filte
