While Buick’s Grand National rode on the same 1960s-design underpinnings as the 442 and Monte Carlo SS (perimeter frame, coil springs, A-arms and ball joints, and solid rear axle), under the hood it packed some advanced technology. Turbocharging was nothing new when Buick applied it to its V-6 engines in the 1970s, but it came of age under the hood...

Transmission and Differential
All Grand Nationals changed gears via GM’s TH-200-4R four-speed automatic transmission. The valve bodies on these 200-4Rs were calibrated for firm shifts and shift points tuned to the turbo V-6’s power delivery. The GN’s transmission also used a stronger intermediate servo assembly and more. The 200-4R is generally a reliable transmission and it predates computer transmission controls, which is a plus in terms of simplicity. These transmissions used a throttle-valve cable rather than a vacuum...

The rear was a four-link design with upper and lower control arms. Grand National-specific, chrome-steel wheels measuring 15 x 7 inches were part of the package and they were shod with 215/65SR15 Goodyear Eagle GT tires. Cha...
