Parts & Accessories Spare parts For sale: Lexus 350/GS300 gearbox. Model 2006, Saudi, rear-wheel drive. Its oil is clean. The gearbox was removed and replaced with an imported one. I expected the problem to be from it because everyone agreed it was the gearbox. After installing the imported gearbox, the problem still existed. I changed the car's computer and it was fixed. So, the first gearbox is, God willing, sound. Price: 750 SAR. Negotiable within reason.
