• Read that warranty closely, especially concerning what the warranty defines as "powertrain"and the various parts of it, how long the warranty is and what costs will be paid as time goes on. After a given time or mileage parts but not labor may be covered, later own only a part of the costs are covered.The warranty may define words differently than general usage. "Powertrain" is usually defined as the engine and transmission as a unit, including the clutch or converter between them. The warranty usually doesn't include the clutch disc inside the housing , it is designed to wear out sacrificially instead of other more expensive parts. The word "engine" usually means what is called a "long block" or every thing except what can be taken off the engine without removing the valve cover or oil pan. Basically the 'innards',pistons,rings,head, valve train, oil pump,rods, and shafts etc. sometimes,but not usually, including the intake and exhaust manifolds, which may be covered under another warranty.. But the oil pan and cover themselves may not be covered. Sometimes the "engine" is a "shortblock", technically just the stuff below the cylinder head less the oil pump, this is common on engines with an aluminum head on an iron block, sometimes the head is covered but the camshaft and valve train may not be, they may be covered under another warranty. Some really good warranties may also include the 'drivetrain', adding the driveshaft(s),axles, trans-axles, possibly even differential or constant velocity joints. Most warranties usually specifically exclude certain parts like differentials, CVJ and 'wear parts' like clutch plates. So, "Powertrain"- the engine and transmission unit. But read that warranty carefully, a few years back a guy I know bought a car and paid extra for what seemed like a super powertrain warranty, based on months and mileage and especially for the time. Then he had to use it. After digging out all the receipts to prove he'd changed the oil as required ( actually better than required) he discovered the warranty covered labor for inspection, disassembly, ( it was after this point that the discovery of coverage was made) and parts, but not labor for installation and reassembly. That's the most expensive part. The shop-monkey ( broom pusher) can take it apart and look at it, but the highest paid guy in the shop is required to put it all back together. At least after it was all put back together, the highly paid, highly factory trained "techician" said, "Here, we had these left over," and handed a big handful of free nuts, bolts, and odd little gizmos to guy I knew.
  • After you’ve considered the model, bells and whistles and the price of a car, one of the most important features to compare when purchasing one is the warranty offered by the manufacturer. A powertrain warrantywarrantywarranty covers all or part of the powertrainpowertrainpowertrain of a vehicle, which is made up of the engine, transmission and drivetrain. Essentially, the powertrainpowertrainpowertrain is the system that powers the car, and then transfers that power to the transmission, then finally to the wheels of the car. When a mechanical problem occurs with a covered part of a powertrainpowertrainpowertrain, the manufacturer or auto dealership will pay to have it repaired. What exactly is covered, and to what extent varies enormously
