The 1969 Trans-American Championship was the fourth running of the Sports Car Club of America's Trans-Am Series. The championship was open to SCCA Sedan category cars competing in Over 2 liter and Under 2 liter classes.[1] 1969 marked the end of the use of co-drivers in the Trans-Am Championship, as most of the races were between 2.5 and 3 hours. The Over 2 liter and Under 2 liter Manufacturers' titles were won by Chevrolet (Due in large part to Mark Donohue's 6 wins, and a major crash at the St. Jovite, Canada race that nearly destroyed all the Ford and Shelby team cars.) and Porsche (Due in large part to Peter Gregg's 7 wins) respectively.[1]
