V5 GUO

For my experience, IS250 auto gearbox is one of the quickest single-clutch gearbox in the market. It always changes gear in a very short time and normally i cant feel that when i was driving. This is one of the best parts for Lexus i thought which is still famous for and popular. If you press the gas gently and look the speedometer, the gear is changing approximately between 1500rpm and 1800rpm. e.g. doing 20mph with 4th gear and 30mph with 5th gear. However, the car not loss any power you want even its doing 30mph with 5th gear. I just push the gas a bit and see the rpm straight goes up without changing to a lower gear. 2.5 litre v6 engine comes with 205bhp is really nice OTR.- - Im not quite familiar with car technology. This is just some of my experience and understanding. If these can help you that would be great.- - Thanks

I think WALD can help. just google wald. I really like what they've done on the IS250's body kit and exhausts. Thanks
