Hey Scotty I have a 2004 Impala SS Indianapolis Limited Edition with the L67 GM 3800 supercharged. I don't mod it, just maintain it.
My question is, should I change the transmission fluid? I know these transmissions are generally weak and I want to change the fluid but the old guy I bought it from never changed it and it has 230k km / 143k miles on her so I'm debating on if I should just change the filter and not touch the fluid. I plan on driving this car forever. It shift normal.
Thanks in advance!
