Anybody know when the Civics got lockup torque converters?
I'm sure they've had them since at least the '88 model year. The '88-91 models have a single stage (on/off) lockup mechanisim. The '92-95 years have two solenoid valves which allow for more precise control of the lockup mechanisim... It allows for partial lockup, whatever that means. '96+ years have additional computer control which also tinkers with shift points and such.
