Your car's manual transmission fluid is more important than you think. Though it doesn't have to be changed as often as motor oil, fresh gearbox fluid keeps your stick-shift transmission from overheating and tearing itself apart. That's why Jason Fenske from is here to show you how to change your car's transmission fluid right in your garage.Since manual transmissions do their jobs through a lot of metal-to-metal contact, they need lubricant to soften touch points and keep everything running smoothly. Over time, that fluid gets dirty and worn out, and needs to be changed.The first step is getting your car in the air and sitting level. This lets you access the transmission and insures you'll fill it to the correct level.Next, find the fill plug on the upper portion of the transmission housing and unscrew it.

Then, find the drain plug, and undo that to drain the gearbox. Make sure to have a catch pan ready.After everything's drained, reinstall the drain plug with a new washer, and refill the transmission, using a transfer pump to get the fluid up into the filler hole.Replace the fill plug with a new washer, clean up any excess fluid, and boom, you're done. Pretty easy right?Fenske put together a thourough video walking us through how to change the transmission fluid on his personal Honda S2000. It goes into great detail, so if you're getting ready to swap out your own car's fluid, it's a must-watch.

Could produce excessive pressure on seals. Normally there is a drain bolt just loosen it, but do not remove it all the way. Till it starts to trickle measure it in a clean painters cup at 1/4 quart tighten the plug back up. Recheck level after waiting 20 mins.I dunno about that being hard to access the plug. You could aim for 1/2 a quart but, that might be a lil too much though if its a clean container u can use what you had trickle out to refill to proper level.Just be careful and slowly spin the plug stopping every 1/8 turn for 20 Mississippi. Its how all techs fix overfill problems.Cause it is easy to make a mistake or not account for a torque converter etc.

Once u see any fluid turn in much smaller increments. Done, I removed a bit less than 1/2 quart. Thanks again for the helpful information.I am suprise to see that the fluid is quite dark (I did one flush 6 monts ago, I know it took me a lot of time to fix the overfilled situation). Is it normal or the overfilled situation could have ruine the fluid?One last thing, I noticed that the housing assembly joint of the transmission is a bit wet all peremeter.

It is like the fluid under pressure started to leak slowly. I hope it will stop now that I got the correct level.Any input would be highly appreciated.

Best regards,Please or to join the conversation. Unless you drained the torque converter you did not drain all the fluid out of your transmission. Torque converters hold a lot of fluid so this is more then likely why it is incredibly dark. Other things like towing items can be really hard on transmissions. Having the automatic shift then jamming on the gas is another thing that can cause excessive wear. Also does it smell burnt?

Do you have a transmission cooler how clean are the fins for it etc Since you are draining at the bottom you might just be getting all the junk. There are a lot of factors at play it isn't just oh its dark or black it is this.Also some trans fluids change color once they have been exposed to heat.

Servicing the fluid in a Honda transmission by opening the drain plug only nets you about 1/4 of the total fluid capacity. Once the fluid gets dark it will take several changes to get the fluid to a clean condition again.

You're basically going to have to change it 4 or 5 more times doing the drain and fill method to get a 'complete' fluid change.Transmission fluid leaks are actually relatively easy to find as the source of the leak is usually clean. Basically you have to find the highest point of the leak and start there. Given the age I would be suspect of the seals around the valve cover and cylinder head area. 50/50 shot on it slowing or stopping. Normally though once its started it isn't going to stop.What he means is where the fluid runs from a leak it normally cleans the dirt off because of the number of detergents in ATF fluid. So there will be a cleaner line where the ATF is coming out.

As with all leaks find the highest point and that is normally where the leak is at. AKA if it was a coolant leak it could be dripping at the bottom of the radiator but, leaking at a heater core line running to the radiator and running down and dripping off the bottom. So follow the clean spot/fluid to where it originates aka the highest spot because until we get anti gravity on cars all fluids obey gravity.
