good question anybody know?!?! i have a 97 jetta... i hear there is a fill and drain plug but how do you know if it needs it or not there is not dip stick! so what if it is a solid casing mine isnt running right and i cant check the fluid and that is REDICULOUS!!! I probably need a tranny service that can add up to $300 if i want the lifetime fluid! JUST GIVE ME A DIP STICK TO FILL IT IN AT AND I"LL KEEP FILLING IT!!! but no now i have to spend moneys i dont have for something that should cost a fifth of the actual cost. THANK YOU VOLKSWAGEN!
