Hi Mates, Please advise me if anyone come across: Uphill while step on gas pedal,there was a whining sounds! On & Off lag & come back Max respond With A Crunk Sounds(the crunk sounds usually appear while Light throttle.......up..down...then the crunk sounds appear,can feel like it hitting the gear to go) On & Off full throttle,stall speed on 1st at 2000rpm,hesitation across 2500rpm & false to upshift to 2rd gear & lag again. On flat road,on & off loss response at 2000rpm while on slow drive! Can't really estimate to overtake cause when need to heavy load on gas pedal,it totally lag for 2 seconds! every time turn switch to 1(before engine start),there was a crunk sound(like something stuck&force to move)Seem the crunk sounds coming from behind! BUT THE GEAR BOX TOTALLY DIDNT SHOW ANY FAILURE CODE ON DIAGNOSTIC,NO GEARBOX WARNING SIGN APPEAR OR NO CAUSE ANY LIMP MODE. Slipping Clutch? Torque Converter Issue? Engine issue? Please advise.
