Hi guys im new to this forum and would kindly appreciate any help with this matter. I own a 2007 3mps and its developed this rather annoying squeaking wong wong sound. I have read the definitive gearbox post and i have changed my gear box oil to the penrite 75w90 full synthetic, but the noise is still there. It occurs after driving for a few mins. It doesn't matter if its cold or warm weather. Mostly recognizable on low speeds <25 kmph applying some clutch and throttle. Its also very noise upon driving over a speed hump. The noise isnt to loud when cruising in 3rd - 4th gear. I dont know where to start looking and the noise is a real pain. Any help would be appreciated. Thanks
