can someone tell me how to drain and change the oil on my tranny???

 

its on a 1990 honda civic dx. 5 speed

 

There is a drain plug on the underside of the trans, it's a 17mm bolt. Remove this, it will drain out. Replace the plug. Refilling the trans you can do one of 2 things, you can use the filler hole right next to where the clutch cable is. this is sometimes capped off, it's a tube that sticks up about 2 inches or so off the trans. Or on the side of the trans, iv seen people use the fluid check hole to fill their trans. You can refill the trans with 30w oil or synchromesh or you can buy honda MTF from any dealership.

 

You want to make sure you can get the filler plug
loose before you drain it..

There are some pics posted here of the
drain,filler hole,and alternate locations to add fluid:
