i just purchased a daily driver,its a 88 volvo 740.my problem is that its stuck in winter mode,which means the car will only shift to third gear as its job is torque for the snow.does anyone know about this problem and any advice on how to disengage it? theres a button on the shifter to disengage it but its not working.i thought about resetting the ecu but im not sure if its gonna work...
