The car was invented to get commuters directly from point A to point B, which made life easier but destroyed the once-thriving tourism industry of Point C. Visit all points on the map with today's Groupon: for $55, you get a transmission service at Conejo Transmission in Thousand Oaks (a $120 value).

Conejo's expert crew of auto mechanics carefully opens each gearbox as if it were an exquisite Fabergé egg, flushing out its grimy funk and restoring it to elegance with fresh transmission fluid and a full tune-up. Mechanics subject each vehicle to a seven-step diagnostic process, first correcting fluid levels and checking all motor adjustments related to the transmission. After more tests for leaks and malfunctions, technicians review their findings with customers and begin the comprehensive service, which includes a pan removal, filter change, and up to four quarts of revivifying transmission tonic. The service also includes a screen cleaning and external adjustments. Though not included with this Groupon, late-model vehicles will also benefit from a transmission flush, in which a cleaner clears away gum, varnish, and lottery tickets. A transmission flush requires 12-15 quarts of fluid.

The full transmission service takes roughly one to 2.5 hours and can be adapted to all car models.

Should your transmission already be in tiptop shape, this Groupon may be applied toward a slew of other automotive services or one hour of repair labor.
