My Bonneville Lost It's Cruise Control About A Month Ago. Then Over Time My Speed Sensor On My Cluster Started Fluctuating Wildly And Abruptly. Then My Car Began To Shift Wildly As Well. It Clunks In Every Gear. And When It Reaches A Gear And The Speed Sensor On the Cluster Starts Dancing...It Starts Shifting All Over The Place. Jumping From Third To First The Over Correcting Back To Fifth And Ugh! I Said Fine, Speed Sensor. I Had The Output One Replaced. Problem Remained. I Was Told That It Was The Input Sensor. Since Then I Have Taken My Car To Various Transmission Shops And They All Tell Me The Same Thing. "It's Not Something They Can Fix, It's An Electrical Problem." Okay...So Who Can Fix It? I'm So Frustrated...I Have Even Gotten A Ticket For Speeding Behind It. I'm Guessing That It's Is Some Electrical Wires That Have Gone Bad, And Basically The Computer Can't Tell At What Speed The Car Is Going, So The Transmission Shifts Thinking It Needs To When It Doesn't. Idk Has ANYONE Had This Problem Before?
