BCM
Body Control Module (BCM) It's separate from the engine processor. And I bought a posi for 3.73s. Chevys used to be this way(maybe still are?), if you want 3 something gears (example 3.73) you needed a 3 series carrier/posi if you wanted a 4 something (example 4.10) you needed a 4 series carrier/posi.Also... what is this BCM issue thing? Curious what I need to watch out for.
