Trying to locate a transmission control module for this truck. Tried Google search and checked every source listed. GMC dealership says it is not available. HELP!

Allison TCMs are backordered pretty much everywhere. Been fairly hard to get lately.
Best bet is either used or searching the forums and groups on Facebook for someone that has a new one they'll sell

Yeah, I'd be hitting up local junkyards, used-parts places, local guys parting out their trucks.
