I was curious about the transmission fluid level in a 2002

Customer Question

I was curious about the transmission fluid level in a 2002 VW Golf. Every now and then, when applying the gas, it jerks into gear.
JA: Thanks. Can you give me any more details about your issue?
Customer: Not really, it is my son's car and I am not in it that much, but I was the last couple of days and he told me it shifts hard on occasion
JA: OK got it. Last thing — VW Mechanics generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
