I have a 2001 Acura CL with 44K miles. I recently visited the dealership to address the recall on the automatic transmission and was subsequently informed that the transmission is fine. However, the transmission fluid does need to be changed (has never been changed). I opted not to allow the dealership to do the work since their price appeared to be a bit gouching. Can anyone provide me with the details to change the transmission fluid and if necessary the filter. Additionally, can anyone provide me with the details to change the cabin filters. These are the filters that filter the air inside the car. Thanks.
