Is there any way to determine the Build Date or Serial Number for an Allison LCT1000 6 speed in a 2010 GMC Sierra? The VIN # is 1GT4K1B62AF107097 (This is the title number, but the tag on the truck is missing the last 7 --worn off or didn't print). I'm asking because the cheap stick on tag is missing from the transmission (great going GM, saved a nickel by eliminating the metal tags)
10 days and no replies? That's unusual.
Maybe one of the admins will jump in here.
Robyn or MorePower?
Info can be found on your RPO/Build sheet (glove box sticker), but it won't reference actual serial numbers for any component. A full printout can be had from a dealer, but they may not show it, either. You'll need to have a dealer contact a regional service representative to obtain factory build details. Probably not a "free" service, but it's free to ask.
