Why Buy a 1999 Chevy Transmission from Auto Power Source
Every 1999 Chevy transmission we ship has been pulled from a low-mileage donor vehicle, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Our ASE-certified technicians fully evaluate every unit before any sale is approved.
Each unit went through our six-step inspection — VIN-matching, ASE testing, noise & smoke verification, full visual inspection, multi-angle photography, and palletized shipping. We have shipped over 46,000 engines and transmissions with a 0% fitment-related return rate.
You pay a fraction of dealer-new pricing for identical OEM Chevy engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and have 30 days from delivery to return for any reason — no restocking fees. Up to a 3-year warranty covers you if anything goes wrong after install.

1999 Chevy Transmission Buying Guide
Five things to verify before buying a 1999 Chevy transmission:
- Match the transmission code by VIN. The 1999 Chevy platform offered multiple transmissions — automatic, manual, CVT, DCT — across trims.
- Confirm 2WD vs 4WD / FWD vs AWD. Case, tailshaft length, and transfer-case mounting differ between drivetrain layouts.
- Verify gear count and torque rating. Many 1999 Chevy models share a family code but differ in gear count and capacity.
- Inspect known weak points for this generation. Our ASE-certified technicians bench-check every unit before listing.
- Always run the donor vehicle VIN if available. We provide donor VIN on request for any 1999 Chevy transmission in inventory.
Our ASE-certified technicians verify every one of these points against your VIN before any unit ships.
