98 civic ex with b18b1 swap how can i check to make sure my tranny fluid is full or do you basically drain and start over with another 2.5 ct

 

Open the fill plug and fill it intill it overflows. If you open the fill cap and stuff comes out then your good.

 

Put the car on level ground, remove the 17mm fill bolt on the pass. side of the tranny (near the axle). If nothing comes out, fill it until it starts to dribble out. Doesn't need to be an exact amount in there, a little more is better than a lot less.
