I hate to say this, but you seem to like to learn lessons the hard, expensive way..........And considering you only get payed 7.25 an hour, you do not have much to throw away to begin with...........
How many times have people told you to get a B15 gearbox in the first place? Also how times have people (including myself) told you to use 85W140 in the gearbox??
When you blow the B15 gearbox (and watch all that money go up in smoke with it), contact me. I will buy your car for $1500 on the spot................
You have seemingly asked the same question(s) hundreds of times, even after searching and getting your answers from the higher ups. Either way, its not my hard earned money at waste here...........
Goodluck.......
