If you're driving a GM truck with a 10-speed Allison transmission, this calculator helps you decide whether to invest in an aftermarket preventative fix or lean on your factory warranty. It uses your current mileage and modification status to recommend an action plan and estimates your upfront out-of-pocket costs, including refundable core charges. Just keep in mind that the "Total Saved" figure represents a worst-case scenario—it assumes a guaranteed catastrophic transmission failure if you skip the upgrade while out of warranty, so your actual savings will depend on your truck's real-world reliability.
