Hey Scotty I'm a first-time Lexus owner and I have a 2002 Lexus RX300 with an unusual problem. When I drive my car on cold mornings 30°f-40°f the car struggles to accelerate at first even if I turn the overdrive off. It's only after the temperature needle gets halfway to its normal operating temperature that the car accelerates normal. Never had this happen on a GM car but then again I've never had reliability on a GM car either. Is this normal for a Lexus?

Can you determine if the transmission torque converter is locked up? If it's inappropriately locked (when cold), it will kill acceleration. Troubleshooting a U140 atm with similar issue.
Get/connect ODB2 scanner, record values and let's go from there.
