Hey guys I just bought an 01 is300 last week and have noticed a weird noise under acceleration.
It in an e-shift with 130k miles
It only makes the noise under quick acceleration.
Its not there if i accelerate slowly or if I go WOT.
The noise is a faint GERRRRRR type sound.
It comes on at around 3k rpm up until right before the car shifts then the same thing.
The only mod is a K&N intake but this noise isnt the intake sound.

Any ideas or insight will be apperciated. :confused:
