Dump truck totaled my 97 LS400 so I moved to a 2003 LS430. I've noticed a very fast shift pattern in normal traffic. Starting out with selector in "D", transmission shifts to 2nd by 10mph, 3rd by 15mph, 4th by 18mph or so then maybe into overdrive our maybe downshift again in response to more throttle. Is this normal for the 430? I didn't know if some electric control regulates or what. It's a "certified" car and has the warranty. Should I press the dealer?
Thanks for any help anyone can provide!
