I have an '02 accent 4dr with the 1.6L, and for the last 2 weeks have had OD problems. One morning on the way to work the car started bucking, and the tach shot up and the OD stopped working. I replaced the input/output speed/shift censors, but no luck. No I have to run the car with the OD turned off because if the OD is on, when the car gets up to speed, the OD engages, the tach drops to idle speed, and the car freewheels until it jerks back into third gear and the tach shoots up. While it is in a freewheel mode, if you give it throttle, the tranny acts like it is slipping, and the car will not go any faster. I know this is a lot, but does anyone have any ideas? I would greatly appreciate any help!!
