My trans has an intermittent leak. If its been sitting a few weeks and I go to fire the car up it will piss trans fluid a good amount. Maybe a cup full, Then after it does that it does not leak. Outfront said many 091 leak unless recently built but this car is old so it will leak and I am fine just topping off.
My dilemma is that the previous owner "thinks he was using" Valvoline 90w but not 100%sure since it sat a few years then got it running and duning. Spoke to guys at Car Craft and they said it should be synthetic and thats all they put in their VW trannys. But also said since previous owner used Valvoline then continue to use it.
WHAT IF it was not valvoline say its synthetic and I top off with Valvoline am I gonna do major harm? What would you guys do if you were in my shoes, drain and fill with syn or stick to Valvoline 90?
