hi everyone, mey name is luis and i am from portugal and i have one question: does anyone knows how to change the valvoline of the gear box of the civic 1.3 ex 1994
thanks

 

It's a manual transmission I assume. Check the DIY section of this site. But it's real simple in any case. Find the drain plug on the bottom of the transmission, it unscrews by putting the 3/8 square drive of a socket wrench in it with no socket. Drain it and screw the plug back in. Then open the fill plug, it's on the right side of the transmission near the back and unscrews with a 17mm wrench. Using a funnel and hose, pour new fluid in until it overflows (slightly more than 2 quarts) then put the fill plug back in.

 

hi mk378
just one more thing
were is the drain plug?
i can´t find it, and yes it´s a manual transmission
thank you for all your help

 

It's on the very bottom on the outside, toward the right wheel of the car. It looks at first like it might be one of the bolts that holds the case together, but it has a plain round head with a square hole in it instead of a hex.

 

one more thing, what car doyou have?
thank u again
