If the crankshaft (Fig. 21) needs to be replaced on 2014-2015 Corvette, Silverado, Sierra; 2015 Tahoe, Suburban, Yukon/XL and Escalade models equipped with the 4.3L, 5.3L or 6.2L engine (RPOs L83, L86, LT1, LV3), be sure to follow these guidelines before completing a crankshaft replacement:

Complete all appropriate Service Information diagnostics to determine that the crankshaft requires replacement.
If the engine has bearing and crankshaft damage, the engine should be replaced along with the oil cooler.
On dry sump engines, the oil tank and lines should also be replaced with the engine.
Follow the latest version of Bulletin #09-06-04-026G to verify that the ECM calibration is not an aftermarket calibration.
If a Corvette owner prefers to keep the original numbers matching with the engine, call TAC for repair directions.
