• Purchase a new or rebuilt transmission from the dealer. It is usually available with a 3-year or 36K miles warranty on parts and labor.
• Purchase a rebuilt transmission from independent company. It is usually available with a 1-year or 12K miles warranty on parts and labor.
• Rebuild your original transmission. It is available with a 1-year or 12K miles warranty on parts and labor.
• Purchase a used transmission. It is available with a 6-months and unlimited mileage warranty on parts only.

For manual transmission repair, please see Clutches section.

Transmission is the gearbox that multiplies engine torque via gear reduction and/or torque conversion. A typical manual transmission has four or five speeds, with the final or highest gear being either a direct 1:1 drive ratio or an "overdrive" ratio (less than 1:1). An automatic transmission first multiplies engine torque as it passes through the fluid coupling known as the "torque converter" and then through three or four separate gear ratios. A manual transmission usually gives slightly better fuel economy than an automatic because there is a certain amount of slippage that occurs in the automatic's torque converter. A manual transmission is normally trouble-free-except for the clutch, which can be very troublesome if adjusted incorrectly or abused. With automatics, the leading problem is fluid breakdown from overheating. Fluid and filter changes every 30,000 miles can avoid premature transmission failure but few people heed such advice. Consequently, automatics often call it quits long before they realize their potential design life. Automatic transmission is a type of transmission that shifts itself. A fluid coupling or torque converter is used instead of a manually operated clutch to connect the transmission to the engine. Newer automatics use electronic controls to regulate shifting and torque converter lockup.
