Having trouble with your Lexus GS300 ECU?

We commonly see these Lexus GS300 ECUs for shifting issues.

The Lexus GS300 is a very nice luxury vehicle,
and we see the GS300 ECU fairly often.
The 2004 - '06 range GS300 is the most popular,
usually coming in for repair of hard shifting issues,
but other problems as well.
We replace the parts that are responsible for these
symptoms, which will restore full function of the ECU.
We also go a little further, and replace some of the
components that have not failed yet,
as a preventive measure to ensure a long life. 

GS300 ECU Repair and Return Service is $250.
includes return shipping - 5 year warranty.

We do not normally keep repairs more than a day or so.
