Most all of the 1993 Honda Civic model vehicles came equipped with automatic transmissions. The transmission fluid protects all of the moving parts inside of the transmission, such as the gears and the bearings. The fluid also protects the seals inside of the transmission. The protection process works by the fluid bonding to all of these components to protect the moving parts and bearings from heat friction and to protect the seals from cracking and hardening. Honda recommends replacing the transmission fluid between 70,000 and 100,000 miles for maximum transmission protection.
Drive the 1993 Honda Civic around for ten to fifteen minutes to heat up the transmission fluid. This will enable more fluid to drain out of the transmission.
Park the Civic on a level area and turn the engine off. Open the hood and apply the parking brake. Jack up all four corners of the Civic and place the safety stands under each designated jacking point. Lower the jack so that the Civic is sitting securely on top of the stands. The car has to be level for all of the fluid to drain out of the transmission.
Slide under the car near the passenger side door and locate the pan on the bottom of the transmission near the front passenger side wheel. Place the catch pan underneath the transmission pan. Loosen and remove the magnetic drain bolt from the bottom of the transmission with a ratchet and a metric socket. Wait for all of the fluid to drain out of the pan and then screw the drain bolt back into the bottom of the transmission with your hand until it is tight. Tighten the plug with the ratchet and socket until the plug is tight. Give the plug another one-quarter of a turn with the ratchet and socket to seat the plug to the transmission pan. Remove the ratchet and socket from the plug.
Pull the catch pan out from under the Civic. Move to the front passenger side of the vehicle and locate the red transmission dipstick on the passenger side rear of the transmission. Pull the dipstick out of the tube and place it on a clean surface. Insert the long neck funnel into the tube and pour in 3.5 quarts of the Honda Genuine Automatic Transmission fluid. Pull the funnel out and reinsert the dipstick.
Crank the engine and let it warm up to operating temperature. Hold the brake down and shift the gear lever through all of the gears and then back to the park position. Keep the engine running and check the transmission fluid level on the dipstick. The fluid level should be on the full mark because the 1993 Honda Civic transmission only holds 3.5 quarts of transmission fluid. Put the dipstick back into the tube and close the hood. Turn the engine off.
Jack the Civic back up and remove all of the jack stands. Lower the vehicle to the ground and remove the jack.
