1991 Other Oldsmobile Models V8 Two Wheel Drive Automatic 144000 miles
91 old custom cruiser (B body station wagon like caprice or roadmaster 5.0 V8 rear wheel drive AT)
Speedometer started acting erratically now tops out @ 20mph no matter how fast you go. Cruise control quit working too. So far it has not turned on the check engine light. I have a 91 chevy wagon just like it but no options(no cruise ect). I can swap the sensor on the tranny, but if that doesnt solve it, what next?
