🔍 Is upgrading cheaper than the cost of new transmission?
🛻 Warranty & Usage
Deciding whether to upgrade your GM 10-speed Allison transmission comes down to your warranty. As AutoMotive Inquiries puts it, if you're under 100,000 miles and your truck's been going good, AutoMotive Inquiries would ride it out. Modifying the transmission gives dealers an excuse to void your coverage.
Your usage also matters. If you lift your truck, tow all the time, or use bigger tires, you put more stress on your drivetrain than a stock version.
💰 Aftermarket vs OEM Costs
Once you are paying out of pocket, compare the preventative cost of an aftermarket kit against a catastrophic failure. As AutoMotive Inquiries explains, a new transmission is probably $8,000 to $9,000 for a used or rebuilt one from GM.
In contrast, aftermarket upgrade kits run around $1,500 plus labor. They sell kits with those cores, which might look like $2,000, but you get that back upon returning your old parts.
