Hi Scotty, love what you do. Thanks for helping us all out with our car questions.

I've had a 1998 Lexus LS400 with almost 300,000 miles on it. I noticed it's been shifting poorly lately and I want to do a transmission fluid change. I purchased the car about a year ago and the previous owner said he doesn't remember ever doing a transmission fluid change. Will changing the transmission fluid on my LS400 this late ruin my transmission?
