I changed my cv axel and lost quite a bit of gear oil in the process. Ive read all over the net that the check plug in on the front of the tranny but all i see are 2 lttle bolts i cant find which bolt i fill thru. It is a klze swap with 5 speed manual from the original 1.8 gs someone please help as i am driving the car and dont want to cause damage from low oil.
