1995-1999 OLDSMOBILE AURORA Change Trans Fluid Message Reset



After much research and development, the Aurora went into production on January 24, 1994, and was released for the 1995 model year. It hosted a number of luxury and technologically advanced standard features including dual-zone climate control, driver and front passenger airbags, leather seating surfaces, genuine burl walnut interior accents, six-speaker sound system with in-dash cd-cassette, and eight-way power adjustable front seats with two-position memory. An onboard computer displaying the date, current gas consumption, and other information was also standard, and was mounted in the center of the dashboard, above the factory radio and climate controls. Only a few options were available on the Aurora including power sunroof, Bose Acoustimass premium amplified sound system, heated front seats, and Autobahn package.

The Aurora also came standard with Oldsmobile’s 4.0 L (244 cu in) L47 V8 engine, a DOHC engine based on Cadillac’s 4.6 L Northstar V8. The Northstar engine and 4T80-E had been exclusive to Cadillac prior to the Aurora. The L47 put out 250 hp (186 kW) at 5600 rpm and 260 lb⋅ft (353 N⋅m) torque at 4400 rpm.[7] The Aurora used a four-speed automatic transmission with driver selectable “normal” and “power” shift modes. A highly modified 650 hp (485 kW) version of this engine was used by General Motors racing division initially for Indy Racing League and IMSA competition starting in 1995 with the GM-supported Aurora GTS-1 racing program, then was later used in the Cadillac Northstar LMP program in 2000. Both engines retained the 4.0 L capacity, but the Northstar LMP version was twin-turbocharged. The Aurora had a drag coefficient of 0.32.

The Aurora was highly regarded at the time for its refined engine, excellent build quality, well-balanced ride, and structural integrity. During normal crush-to-failure tests done by automakers to evaluate body torsional rigidity, the Aurora’s unibody construction broke GM’s testing machine. A frame-crusher otherwise used to test stronger truck frames had to be used instead, with the car exceeding federal standards for passenger cars by two times.

All first-generation Auroras were built in Lake Orion, Michigan, along with the Buick LeSabre, Buick Park Avenue, Buick Riviera, Oldsmobile 88, Oldsmobile 98 and Pontiac Bonneville. Production for this generation ended on June 25, 1999.
