I want to drain the transmission fluid and clean it and put new in, what is the step by step procedure?

My engine comes on when I start the car and maintemance required, do I use a scan tool to see what's wrong and where do I connect it?

1. Warm engine to normal operating temperature.

2. Remove transmission dip stick and, using a 3/8" ratchet, remove transmission drain plug. Approximately 2.9 quarts will drain out (initial fill). Total fill is 6.4 quarts; therefore, you will remove less than half of the fluid.

3. Reinstall drain plug and add approximately 2.9 quarts of fluid--I recommend Mobil 1 Synthetic ATF.

4. Start engine and move the gear shift lever through each gear, pausing 5 seconds each time.

5. Drive the car and allow it to reach normal operating temperature. Make final fluid adjustment with the engine hot and idling in Park. Don't overfill.

First of all if your car has at least 60k on the mileage then you should do a drain and refill of the auto transmission fluid. After that repeat this every 60l miles. A drain and refill is only done by locating the drain plug which is an internal wrenching or ( recessed 3/8" square shape) plug. Use a 3/8" ratchet wrench by is self. After lifting the vehicle with a jack in the proper location and support it with safety stands remove the plug and drain the fluid into a suitable pan that will hold at least 3 quarts of fluid. The automatic transmission actually holds double that but when it is drained it only drains the case fluid and not the torque converter. Depending on the condition of the fluid ( coffee black ) in color or mileage you would then want to do a complete fluid flush. A complete flush is a case of fluid Honda ATF-Z1 (12 qts ) which is a drain and refill 4 times. Warm you car up by driving it about ten minutes, then raise it up and drain it.t Afer it has drained be sure you replace the aluminum drain plug gasket with a new one and re-install the plug securely. Refill it with 3 qts. ATF then while supported start the engine and cycle through all the gears allowing wheels to spin while clear of the ground at idle rpm allowing fluid to circulate for 3 minutes then drain. Refill repeat 3 times until you have use your case of fluid up, then leave in the last 3 qts. You are done. If you only want to freshen up the fluid and get the ebri settled at the bottom out just do one drain and refill. After you have done either type drain and refill to check the ATF fluid level you want the vehicle to be on level ground and NOT RUNNING! Pull the ATF fluid level dip stick on the passenger side rear of transmission with yellow pull loop. Should be between the two dots more towards the top dot is best. Fairly easy work really but the genuine Honda ATF fluid is not cheap, but will save you a load of cash in the long run. Good luck.

It depends on if you mean maintenance required or check engine light. Depending on the make and model year vehicle it is maintenance means you may need service such routine maintenance such as an engine oil and filter change or a scheduled service.

1. Take it to a mechanic shop

2. wait until he finishes

3. pay the bill

4 drive off

5.sleep well, because you know without a doubt it was done right

"...done right..."

Yeah, right, except I just discovered that last time my honda shop did the atf service they left the atf dipstick out of the hole and instead stuck it down beside it, outside the block, so I've driven all winter with a 3/4" hole open to salt, sand and water. Nice.

Will any atf fluid work?

No, it needs to meet Honda's specs.
