Fluid condition, test drives, and warranty options explained.
Fluid tells a story
Dark, burnt-smelling fluid or metal flakes in the pan are red flags. Ask when the transmission was last serviced on the donor vehicle.
Verify type and fitment
Automatic, CVT, and manual units are not interchangeable. Hybrid and tow-package transmissions may have different gearing or coolers.
Test when possible
Some recyclers can verify shift points on a stand or document that the donor drove onto the yard. Request that information before shipping.
Warranty and core policies
Transmission warranties often require professional installation and may exclude seals and external components. Read core return deadlines carefully.
