* Automatic Transmission: Approximately 3.0 to 3.5 liters. It's best to check your owner's manual for the exact specification.
* Manual Transmission: This usually requires less oil, typically around 1.8 to 2.2 liters. Again, consult your owner's manual for the precise amount.
Crucially: Always refer to your owner's manual for the exact transmission oil capacity for *your specific* 1993 Honda Civic. The above figures are estimates and may not be accurate for all models.
