2006 Honda Civic Q&A
2006 Honda Civic Question: how do I change my automatic transmission fluid?
Drive the car get the transmission oil hot.The automatic transmission fluid is changed by removing a drain plug at the bottom of the transmission. The drain plug has a square 3/8 tool to remove it. Allow the oil to drain ,replace the drain plug seal, and refill the fluid trough the dip stick hole (yellow dip stick is located just under the battery area of the engine compartment. Refill with Honda ATF Z1 fluid and check with the engine switched OFF. Drive the car, and switch off the engine recheck the oil level and add oil if required. The trans fluid maintainence light needs to be reset with a scan tool. - patrick mannion
With regard to Answer #2. All good step-by-step advice, but the author doesn't mention the substantial amount of used oil left in the torque converter...which is undrainable unless removed by special equipment that some service places have. So, I feel it would be like changing your oil and not replacing the filter--leaving a quart of dirty oil in the system. So I go ahead and pay the $75 or so to have that done professionally. - DanK5
why not drain the trans fluid once a year when the car is bought new? If you have a drain plug it"s easy. This will mix with the "old" trans fluid around the torque converter and minimize debris. - kaz121
