My VSC and Engine Light started going on every time I filled up the gas tank of my Lexus IS300. Since my battery is bad I thought it may be due to that. I was on the highway and car stopped accelerating. I drove it home slowly when I put in park to open the gate to the driveway the car wouldn't drive or reverse.
My husband changed the battery thinking that was the case. While changing the battery the codes got wiped out and the mechanic said it was the transmission and couldn't retrieve the codes.
How do they know it's transmission and not a sensor or ECU that is causing the transmission not to work? Should I get a 3rd opinion?
Hi Sandi, By checking the fluid level, condition (if it smells burnt) the transmission filter may be clogging up from debris. A transmission shop will be able to diagnosis this for you even though there are no codes. Good luck.

The VSC will come on anytime the check engine light is illuminated on this vehicle. Disconnecting or replacing the battery will clear the codes and adaptive memory stored in the vehicles computer. You may have to drive it for a while before the system resets. If there is an issue shifting that is currently present without any codes stored, a good tranny shop should be able to diagnose if the transmission is bad or if there is an outside cause that is just causing a hard shift.
