Q: problem with transmission pan seal on 2002 Lexus ES300

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My check engine light just went on. I was told several months ago that I would be needing a transmission pan seal...could this be why the light went on?

Probably not, unless you've lost so much fluid that the transmission is not functioning properly setting diagnostic codes and turned the light on. More likely, you have an engine/emissions system control fault and the computer has detected it, turning on the light, storing diagnostic codes and data which could be accessed by a technician with a scanner.
If you want to find a specialist, here's a directory link for you:

PS: Be sure that the transmission fluid is up to level in order to avoid transmission damage due to low fluid.

No. The light came on because of an internal problem. It could be a solenoid or clutch plate problem. You need ot read the code first and then go from there
