Hello. I am thinking about draining and flushing my transmission on my S13. I need to know where the drain plug is on the transmission. Also, how would I flush the transmission? I was thinking of using some good ol' SeaFoam with current fluid in there... then draining and adding some Royal Purple. If i did add SeaFoam, how long should I drive with the SeaFoam/old gear oil in it before draining and changing? Is this something that anyone has done before?
I feel that i should do this as the previous owner(s) weren't exactly good at keeping this thing in its BEST shape... spun rod bearings, theres some rust where the factory wing was taken off (and covered with Muffler tape). theres some minor rust under the car, but not as much as one would expect for a 20 year old car, guess they [prev. owners] managed to do something right...
All aside, any help would be greatly appreciated... Thanks NICO!
