Should I use some lucas stop leak transmission fluid?
I have a 2007 Chevy Impala LTZ with a 3.9L engine and it shifts alright for the milage but can be a little jerky I know Scotty said it was great on old american cars but was wondering if I should try it out. I don't know much of the history of my car off the top of my head since my car had multiple owners and it's my first car. I have 177k miles on it. If i should use some Lucas stop slip transmission fluid how much should i add?
When was the last time the transmission fluid and filter were changed? What is the condition of the fluid now?
