Editing Traction control system (section)

==History==
The predecessor of modern [[Electronics|electronic]] traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a [[limited slip differential]]. A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.

In 1971, [[Buick]] introduced ''MaxTrac'', which used an early computer system to detect rear wheel spin and modulate engine power to those wheels to provide the most traction.<ref>{{cite web|url=http://www.buick-riviera.com/maxtrac.html |title=Max Trac |publisher=www.buick-riviera.com |access-date=2013-11-26}}</ref> A Buick exclusive item at the time, it was an option on all full-size models, including the [[Buick Riviera|Riviera]], [[Buick Estate|Estate Wagon]], [[Buick Electra|Electra 225]], [[Buick Centurion|Centurion]], and [[Buick LeSabre|LeSabre]].

Cadillac introduced the ''Traction Monitoring System'' (TMS) in 1979 on the redesigned Eldorado.
