Ok when I try to downshift into 3rd it won't go in but if I go to second then up to third it goes in is this the shifting fork?
It is my understanding that even the Non WC dont use gear oil that it causes seperation of the rings, but that they aren't as picky as the WC models.WC T5s use ATF fluid. Non WC T5s use 50w gear oil
I ran gear oil in my last non wc trans.I got this straight from modern driveline, the non wc t5s were originally recommended to use dextron II atf but tremec engineers now recommend 50w gear oil. Dextron III may be used but it may effect shifting and wear. So i imagine there are plenty of people running atf in non wcs with no issues
