gs300220

Hi all, just for reference have any of you had to replace the transmission of your gs300 (gen 3) due to the car not shifting beyond 3rd gear? Also is there a fuse for the audio system that (if it blows) would make the radio dead...

Hi all First of all thanks very much for contributing to a forum like this. Its an invaluable read on many issues. I love my lexus cars, Mrs has an IS220D and I have had IS200's all with excellent reliability. Then I bought this GS300 which needs an auto gearbox change. The problem was there when I bought the car, i think it does not shift beyond 3rd gear, so will rev at 4000 RPM/60Mph. Had the P codes for shift soleniods, till I took it to a transmission specialist who found the tranny oil burnt with metal shavings in it. Anyway cut a long story short, I have luckily found another transmission with warranty. My question is how easy it is to change the transmission on the car, can an ordinary garage do it with ease or does it need specialist (transmission specialist) tools? Has anyone done this and did it need any programming after the tranny transplant? Many Thanks Sean
