“Vehicle would remain in lower gears while in normal operation, running rpms up higher than it should have been. Consumer took vehicle to a dealership, who replaced transmission from another vehicle. Vehicle operated normally until september 2000, when transmission would rev up to excessive rpms at speed being traveled. Please provide any additional information/attachments.”

NHTSA complaint #886774, filed 2001-04

“Vehicle stalled out under heavy braking conditions and also at idle. Throttle body cleaned as repaired. Auto continued poor idle. Later, battery became fully drained. With headlights on at highway speeds, engaging brakes or turning on any cabin electrical device would flicker and dim the headlights. Replaced battery and belts for repair. Alternator tested out okay. Poor idling attributed to low voltage to idle speed motor. Continuing issue: engaging brakes flicker and dim dashboard lights. …”
